Let's divide 77397946 by 830
We want to divide 77397946 by 830.

Let's proceed to step 1:
When dividing 7 by 830, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 830

Advancing to step 2:
830 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 830

Advancing to step 3:
773 divided by 830 is 0 with a remainder of 773.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 773, we end up with 773.
Grab the next digit (9) from the dividend, add it to 773, then carry on: 7739 / 830

Step 4:
When dividing 7739 by 830, we get 9 with a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7470 away from 7739, we end up with 269.
Include the next digit (7) from the dividend after 269, then repeat: 2697 / 830

Step 5:
830 can be fit into 2697 3 times, resulting in a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 2490 from 2697, we get 207.
Fetch the next digit (9) from the dividend, attach it to 207 and continue: 2079 / 830

Going ahead to step 6:
830 can be fit into 2079 2 times, resulting in a remainder of 419.
The number 2 becomes the next digit in our result. 
Result so far: 932.0
Subtracting 1660 from 2079 leaves us with 419.
Take the next digit (4) from the dividend and append it to 419, then repeat: 4194 / 830

Let's proceed to step 7:
830 can be fit into 4194 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 9325.0
Subtracting 4150 from 4194 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 830

On to step 8:
If we divide 446 by 830, we get 0 and a remainder of 446.
The number 0 becomes the next digit in our result. 
Result so far: 93250.0
Deduct 0 from 446 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
The number 830 fits into 4460 5 times, leaving a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 93250.5
If we take 4150 away from 4460, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
3100 divided by 830 is 3 with a remainder of 610.
The number 3 becomes the next digit in our result. 
Result so far: 93250.53
Deduct 2490 from 3100 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
When dividing 6100 by 830, we get 7 with a remainder of 290.
Put 7 as the next digit of the answer. 
Result so far: 93250.537
Deduct 5810 from 6100 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 12:
2900 divided by 830 is 3 with a remainder of 410.
The next digit of our result is 3. 
Result so far: 93250.5373
Deduct 2490 from 2900 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 13:
If we divide 4100 by 830, we get 4 and a remainder of 780.
Write down 4 as next digit of the result. 
Result so far: 93250.53734
If we subtract 3320 from 4100, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 14:
830 goes into 7800 9 times with a remainder of 330.
Use 9 as the next digit of our solution. 
Result so far: 93250.537349
Deduct 7470 from 7800 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 15:
3300 divided by 830 is 3 with a remainder of 810.
The next digit of our result is 3. 
Result so far: 93250.5373493
If we subtract 2490 from 3300, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 16:
When dividing 8100 by 830, we get 9 with a remainder of 630.
Use 9 as the next digit of our solution. 
Result so far: 93250.53734939
Subtracting 7470 from 8100 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The quotient of the division is 93250.53734939, and the remainder is 6.3e-07.
