We're dividing 85520657 by 231 
We're looking to find how many times 231 goes into 85520657.

Going ahead to step 1:
231 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 231

Let's proceed to step 2:
If we divide 85 by 231, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (5) from the dividend, attach it to 85 and continue: 855 / 231

Moving on to step 3:
When dividing 855 by 231, we get 3 with a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 693 from 855, we get 162.
Grab the next digit (2) from the dividend, add it to 162, then carry on: 1622 / 231

Advancing to step 4:
If we divide 1622 by 231, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtracting 1617 from 1622 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 231

Step 5:
When dividing 50 by 231, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 370.0
Subtract 0 from 50 to get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 231

On to step 6:
The number 231 fits into 506 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 3702.0
If we take 462 away from 506, we end up with 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 231

Moving on to step 7:
231 can be fit into 445 1 times, resulting in a remainder of 214.
The number 1 becomes the next digit in our result. 
Result so far: 37021.0
Subtract 231 from 445 to get 214.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 231

On to step 8:
231 goes into 2147 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 370219.0
Subtracting 2079 from 2147 leaves us 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.

Going ahead to step 9:
If we divide 680 by 231, we get 2 and a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 370219.2
If we take 462 away from 680, we end up 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.

Step 10:
The number 231 fits into 2180 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 370219.29
Subtract 2079 from 2180 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 11:
1010 divided by 231 is 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 370219.294
Subtracting 924 from 1010 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 12:
When dividing 860 by 231, we get 3 with a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 370219.2943
Subtracting 693 from 860 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 13:
If we divide 1670 by 231, we get 7 and a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 370219.29437
If we subtract 1617 from 1670, we 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.

Advancing to step 14:
231 goes into 530 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 370219.294372
Subtract 462 from 530 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
The number 231 fits into 680 2 times, leaving a remainder of 218.
The next digit of our result is 2. 
Result so far: 370219.2943722
Subtracting 462 from 680 leaves us 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.

The final result is 370219.2943722 with a remainder of 2.18e-06.
