83401331 ÷ 231 
We want to divide 83401331 by 231.

Advancing to step 1:
If we divide 8 by 231, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 231

Going ahead to step 2:
When dividing 83 by 231, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 231

Let's proceed to step 3:
231 can be fit into 834 3 times, resulting in a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 141 after subtracting 693 from 834.
Grab the next digit (0) from the dividend, add it to 141, then carry on: 1410 / 231

On to step 4:
1410 divided by 231 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 1386 from 1410, we get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 231

Moving on to step 5:
When dividing 241 by 231, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we subtract 231 from 241, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 231

On to step 6:
The number 231 fits into 103 0 times, leaving a remainder of 103.
Record the quotient 0 as the next digit in the result. 
Result so far: 3610.0
If we take 0 away from 103, we end up with 103.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 231

Moving on to step 7:
If we divide 1033 by 231, we get 4 and a remainder of 109.
Use 4 as the next digit of our solution. 
Result so far: 36104.0
Subtract 924 from 1033 to get 109.
Take the next digit (1) from the dividend and append it to 109, then repeat: 1091 / 231

Advancing to step 8:
1091 divided by 231 is 4 with a remainder of 167.
The next digit of our result is 4. 
Result so far: 361044.0
The remainder is 167 after subtracting 924 from 1091.
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:
231 goes into 1670 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 361044.7
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.

On to step 10:
530 divided by 231 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 361044.72
Subtracting 462 from 530 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.

Let's proceed to step 11:
231 can be fit into 680 2 times, resulting in a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 361044.722
If we subtract 462 from 680, we 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.

The final result is 361044.722 with a remainder of 0.0218.
