We look at the division of 90915970 by 830 
We want to figure out the number of times 90915970 can be divided by 830.

Going ahead to step 1:
The number 830 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 830

Step 2:
When dividing 90 by 830, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 830

Advancing to step 3:
830 can be fit into 909 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 79 after subtracting 830 from 909.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 830

Let's proceed to step 4:
When dividing 791 by 830, we get 0 with a remainder of 791.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 791 leaves us with 791.
Take the next digit (5) from the dividend and append it to 791, then repeat: 7915 / 830

Advancing to step 5:
830 goes into 7915 9 times with a remainder of 445.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we take 7470 away from 7915, we end up with 445.
Include the next digit (9) from the dividend after 445, then repeat: 4459 / 830

Moving on to step 6:
830 goes into 4459 5 times with a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
If we take 4150 away from 4459, we end up with 309.
Fetch the next digit (7) from the dividend, attach it to 309 and continue: 3097 / 830

On to step 7:
When dividing 3097 by 830, we get 3 with a remainder of 607.
Record the quotient 3 as the next digit in the result. 
Result so far: 10953.0
Subtract 2490 from 3097 to get 607.
Take the next digit (0) from the dividend and append it to 607, then repeat: 6070 / 830

On to step 8:
If we divide 6070 by 830, we get 7 and a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 109537.0
Deduct 5810 from 6070 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
If we divide 2600 by 830, we get 3 and a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 109537.3
If we subtract 2490 from 2600, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
If we divide 1100 by 830, we get 1 and a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 109537.31
The remainder is 270 after subtracting 830 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
The number 830 fits into 2700 3 times, leaving a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 109537.313
Subtracting 2490 from 2700 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
When dividing 2100 by 830, we get 2 with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 109537.3132
Deduct 1660 from 2100 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
If we divide 4400 by 830, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 109537.31325
Subtract 4150 from 4400 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
When dividing 2500 by 830, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 109537.313253
Subtract 2490 from 2500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
If we divide 100 by 830, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 109537.313253
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
When dividing 1000 by 830, we get 1 with a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 109537.31325301
The remainder is 170 after subtracting 830 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 109537.31325301 with a remainder of 1.7e-07.
