We look at the division of 877721 by 85 
Let's see how many times 85 fits into 877721.

Moving on to step 1:
85 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 85

On to step 2:
The number 85 fits into 87 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 85 from 87 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 85

On to step 3:
85 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 27 after subtracting 0 from 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 85

Step 4:
85 goes into 277 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 255 from 277 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 85

Moving on to step 5:
222 divided by 85 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 1032.0
Subtracting 170 from 222 leaves us with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 85

Moving on to step 6:
When dividing 521 by 85, we get 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 10326.0
Subtracting 510 from 521 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
85 goes into 110 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 10326.1
The remainder is 25 after subtracting 85 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
When dividing 250 by 85, we get 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 10326.12
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
85 goes into 800 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 10326.129
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 10326.1294
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 85, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 10326.12941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10326.129411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 10326.129411 and a remainder of 6.5e-06.
