857806 ÷ 87 
Our goal is to divide 857806 by 87.

On to step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 87

Moving on to step 2:
If we divide 85 by 87, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 87

Step 3:
87 goes into 857 9 times with a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 783 from 857 and we're left with 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 87

Going ahead to step 4:
The number 87 fits into 748 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 696 from 748 to get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 87

Let's proceed to step 5:
If we divide 520 by 87, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 985.0
If we subtract 435 from 520, we get 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 87

Let's proceed to step 6:
87 goes into 856 9 times with a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 9859.0
The remainder is 73 after subtracting 783 from 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
If we divide 730 by 87, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 9859.8
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
If we divide 340 by 87, we get 3 and a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 9859.83
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
If we divide 790 by 87, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9859.839
If we subtract 783 from 790, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
70 divided by 87 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 9859.839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
If we divide 700 by 87, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 9859.83908
If we take 696 away from 700, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9859.83908
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
87 can be fit into 400 4 times, resulting in a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 9859.8390804
The remainder is 52 after subtracting 348 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
87 can be fit into 520 5 times, resulting in a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 9859.83908045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 9859.83908045, with a leftover of 8.5e-08.
