We divide 90899708 by 231
Our goal is to divide 90899708 by 231.

Step 1:
The number 231 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 231

Going ahead to step 2:
When dividing 90 by 231, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 231

On to step 3:
When dividing 908 by 231, we get 3 with a remainder of 215.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 693 from 908 and we're left with 215.
Take the next digit (9) from the dividend and append it to 215, then repeat: 2159 / 231

Going ahead to step 4:
When dividing 2159 by 231, we get 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 2079 away from 2159, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 231

Step 5:
When dividing 809 by 231, we get 3 with a remainder of 116.
Write down 3 as next digit of the result. 
Result so far: 393.0
Deduct 693 from 809 and we're left with 116.
Append the next digit (7) from the dividend to 116 and continue with: 1167 / 231

Step 6:
1167 divided by 231 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 3935.0
The remainder is 12 after subtracting 1155 from 1167.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 231

Advancing to step 7:
The number 231 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 39350.0
Subtract 0 from 120 to get 120.
Take the next digit (8) from the dividend and append it to 120, then repeat: 1208 / 231

Going ahead to step 8:
231 can be fit into 1208 5 times, resulting in a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 393505.0
Subtract 1155 from 1208 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
231 can be fit into 530 2 times, resulting in a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 393505.2
Deduct 462 from 530 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
When dividing 680 by 231, we get 2 with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 393505.22
Deduct 462 from 680 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 393505.22 with a remaining 0.218.
