We look at the division of 120747 by 87 
We want to divide 120747 by 87.

Moving on to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 87

Going ahead to step 2:
12 divided by 87 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 87

Going ahead to step 3:
If we divide 120 by 87, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 87 from 120 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 87

Let's proceed to step 4:
When dividing 337 by 87, we get 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 261 from 337, we get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 87

On to step 5:
If we divide 764 by 87, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 138.0
The remainder is 68 after subtracting 696 from 764.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 87

Step 6:
If we divide 687 by 87, we get 7 and a remainder of 78.
The next digit of our result is 7. 
Result so far: 1387.0
The remainder is 78 after subtracting 609 from 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 7:
When dividing 780 by 87, we get 8 with a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 1387.8
The remainder is 84 after subtracting 696 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 8:
87 goes into 840 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 1387.89
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
570 divided by 87 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1387.896
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 87 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1387.8965
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
87 can be fit into 450 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1387.89655
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 1387.89655 with a remainder of 1.5e-05.
