We divide 113391 by 87
We want to divide 113391 by 87.

Step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 87

Going ahead to step 2:
If we divide 11 by 87, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 87

Step 3:
87 goes into 113 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 87 from 113 leaves us with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 87

Step 4:
87 can be fit into 263 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 261 from 263 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 87

Moving on to step 5:
87 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
If we take 0 away from 29, we end up with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 87

Moving on to step 6:
The number 87 fits into 291 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 1303.0
Deduct 261 from 291 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
The number 87 fits into 300 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1303.3
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
When dividing 390 by 87, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 1303.34
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 87, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1303.344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 1303.344 with a balance of 0.0072.
