We look at the division of 39710222 by 231 
We're looking to find how many times 231 goes into 39710222.

Going ahead to step 1:
3 divided by 231 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 231

On to step 2:
39 divided by 231 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 231

On to step 3:
231 goes into 397 1 times with a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 166 after subtracting 231 from 397.
Bring next digit (1) of the dividend behind the 166 and repeat the process: 1661 / 231

Let's proceed to step 4:
The number 231 fits into 1661 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 44 after subtracting 1617 from 1661.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 231

Let's proceed to step 5:
The number 231 fits into 440 1 times, leaving a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
If we take 231 away from 440, we end up with 209.
Append the next digit (2) from the dividend to 209 and continue with: 2092 / 231

On to step 6:
2092 divided by 231 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 1719.0
The remainder is 13 after subtracting 2079 from 2092.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 231

On to step 7:
231 can be fit into 132 0 times, resulting in a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 17190.0
Subtract 0 from 132 to get 132.
Bring next digit (2) of the dividend behind the 132 and repeat the process: 1322 / 231

Moving on to step 8:
1322 divided by 231 is 5 with a remainder of 167.
Write down 5 as next digit of the result. 
Result so far: 171905.0
Deduct 1155 from 1322 and we're left 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 9:
When dividing 1670 by 231, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 171905.7
If we take 1617 away from 1670, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
231 can be fit into 530 2 times, resulting in a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 171905.72
The remainder is 68 after subtracting 462 from 530.
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 11:
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: 171905.722
Subtract 462 from 680 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

After the division, we end up with 171905.722 and a remainder of 0.0218.
