552926 ÷ 855 
We want to figure out the number of times 552926 can be divided by 855.

On to step 1:
5 divided by 855 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 855

Going ahead to step 2:
855 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 855

Advancing to step 3:
If we divide 552 by 855, we get 0 and a remainder of 552.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 552, we get 552.
Grab the next digit (9) from the dividend, add it to 552, then carry on: 5529 / 855

On to step 4:
5529 divided by 855 is 6 with a remainder of 399.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5130 from 5529 to get 399.
Bring next digit (2) of the dividend behind the 399 and repeat the process: 3992 / 855

Advancing to step 5:
855 goes into 3992 4 times with a remainder of 572.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 572 after subtracting 3420 from 3992.
Fetch the next digit (6) from the dividend, attach it to 572 and continue: 5726 / 855

Advancing to step 6:
If we divide 5726 by 855, we get 6 and a remainder of 596.
Put 6 as the next digit of the answer. 
Result so far: 646.0
If we take 5130 away from 5726, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 7:
855 goes into 5960 6 times with a remainder of 830.
The number 6 becomes the next digit in our result. 
Result so far: 646.6
Subtracting 5130 from 5960 leaves us with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 8:
855 goes into 8300 9 times with a remainder of 605.
The number 9 becomes the next digit in our result. 
Result so far: 646.69
The remainder is 605 after subtracting 7695 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 9:
855 can be fit into 6050 7 times, resulting in a remainder of 65.
The next digit of our result is 7. 
Result so far: 646.697
If we take 5985 away from 6050, we end up 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.

On to step 10:
650 divided by 855 is 0 with a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 646.697
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 11:
855 goes into 6500 7 times with a remainder of 515.
Use 7 as the next digit of our solution. 
Result so far: 646.69707
If we subtract 5985 from 6500, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 12:
The number 855 fits into 5150 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.697076
If we subtract 5130 from 5150, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
If we divide 200 by 855, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 646.697076
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
2000 divided by 855 is 2 with a remainder of 290.
Put 2 as the next digit of the answer. 
Result so far: 646.69707602
If we take 1710 away from 2000, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 646.69707602 and a remainder of 2.9e-07.
