Let's divide 781143 by 87
We want to divide 781143 by 87.

Let's proceed to step 1:
When dividing 7 by 87, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 87

Moving on to step 2:
If we divide 78 by 87, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 87

Going ahead to step 3:
781 divided by 87 is 8 with a remainder of 85.
The next digit of our result is 8. 
Result so far: 8.0
If we take 696 away from 781, we end up with 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 87

Advancing to step 4:
851 divided by 87 is 9 with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 783 from 851 to get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 87

Advancing to step 5:
87 goes into 684 7 times with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 897.0
The remainder is 75 after subtracting 609 from 684.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 87

Advancing to step 6:
When dividing 753 by 87, we get 8 with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 8978.0
If we subtract 696 from 753, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 8978.6
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
87 goes into 480 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8978.65
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
450 divided by 87 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8978.655
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.

Our division results in 8978.655 with a remaining 0.0015.
