We look at the division of 867978 by 87 
We want to divide 867978 by 87.

On to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 87

Let's proceed to step 2:
87 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 87

Let's proceed to step 3:
If we divide 867 by 87, we get 9 and a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 783 from 867, we get 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 87

On to step 4:
When dividing 849 by 87, we get 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 66 after subtracting 783 from 849.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 87

Moving on to step 5:
If we divide 667 by 87, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 997.0
Subtract 609 from 667 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 87

Advancing to step 6:
If we divide 588 by 87, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 9976.0
If we subtract 522 from 588, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
If we divide 660 by 87, we get 7 and a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 9976.7
Deduct 609 from 660 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 8:
If we divide 510 by 87, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9976.75
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
The number 87 fits into 750 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 9976.758
If we take 696 away from 750, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
87 goes into 540 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 9976.7586
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
87 can be fit into 180 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 9976.75862
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
If we divide 60 by 87, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9976.75862
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
87 goes into 600 6 times with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 9976.7586206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
780 divided by 87 is 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 9976.75862068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 9976.75862068, with a leftover of 8.4e-08.
