Let's divide 90305699 by 215
We're looking to find how many times 215 goes into 90305699.

On to step 1:
If we divide 9 by 215, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 215

Advancing to step 2:
215 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 215

Step 3:
The number 215 fits into 903 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 860 from 903 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 215

On to step 4:
When dividing 430 by 215, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 430 from 430 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 215

Let's proceed to step 5:
If we divide 5 by 215, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 215

Advancing to step 6:
When dividing 56 by 215, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 4200.0
Subtract 0 from 56 to get 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 215

Advancing to step 7:
569 divided by 215 is 2 with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 42002.0
If we subtract 430 from 569, we get 139.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 215

Moving on to step 8:
215 goes into 1399 6 times with a remainder of 109.
The next digit of our result is 6. 
Result so far: 420026.0
If we take 1290 away from 1399, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
When dividing 1090 by 215, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 420026.5
If we subtract 1075 from 1090, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
When dividing 150 by 215, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 420026.5
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
When dividing 1500 by 215, we get 6 with a remainder of 210.
The next digit of our result is 6. 
Result so far: 420026.506
Subtracting 1290 from 1500 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 215, we get 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 420026.5069
The remainder is 165 after subtracting 1935 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 13:
If we divide 1650 by 215, we get 7 and a remainder of 145.
Record the quotient 7 as the next digit in the result. 
Result so far: 420026.50697
Subtract 1505 from 1650 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 14:
215 goes into 1450 6 times with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 420026.506976
Subtracting 1290 from 1450 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
The number 215 fits into 1600 7 times, leaving a remainder of 95.
The next digit of our result is 7. 
Result so far: 420026.5069767
Subtract 1505 from 1600 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 16:
If we divide 950 by 215, we get 4 and a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 420026.50697674
Deduct 860 from 950 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 420026.50697674, with a leftover of 9e-08.
