We're dividing 840629 by 87 
Our goal is to divide 840629 by 87.

Going ahead to step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 87

Moving on to step 2:
84 divided by 87 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 87

Moving on to step 3:
When dividing 840 by 87, we get 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 783 away from 840, we end up with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 87

On to step 4:
If we divide 576 by 87, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 54 after subtracting 522 from 576.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 87

Moving on to step 5:
542 divided by 87 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 966.0
The remainder is 20 after subtracting 522 from 542.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 87

On to step 6:
209 divided by 87 is 2 with a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 9662.0
Deduct 174 from 209 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
If we divide 350 by 87, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9662.4
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
87 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9662.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
87 goes into 200 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 9662.402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
87 goes into 260 2 times with a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 9662.4022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 9662.4022, and the remainder is 0.00086.
