We look at the division of 52649866 by 855 
We're looking to find how many times 855 goes into 52649866.

On to step 1:
5 divided by 855 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 855

Going ahead to step 2:
The number 855 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 855

On to step 3:
855 goes into 526 0 times with a remainder of 526.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 526 to get 526.
Fetch the next digit (4) from the dividend, attach it to 526 and continue: 5264 / 855

On to step 4:
When dividing 5264 by 855, we get 6 with a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5130 away from 5264, we end up with 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 855

Let's proceed to step 5:
1349 divided by 855 is 1 with a remainder of 494.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we subtract 855 from 1349, we get 494.
Fetch the next digit (8) from the dividend, attach it to 494 and continue: 4948 / 855

On to step 6:
4948 divided by 855 is 5 with a remainder of 673.
The number 5 becomes the next digit in our result. 
Result so far: 615.0
The remainder is 673 after subtracting 4275 from 4948.
Append the next digit (6) from the dividend to 673 and continue with: 6736 / 855

On to step 7:
855 goes into 6736 7 times with a remainder of 751.
The number 7 becomes the next digit in our result. 
Result so far: 6157.0
If we take 5985 away from 6736, we end up with 751.
Grab the next digit (6) from the dividend, add it to 751, then carry on: 7516 / 855

Advancing to step 8:
855 can be fit into 7516 8 times, resulting in a remainder of 676.
The next digit of our result is 8. 
Result so far: 61578.0
Subtracting 6840 from 7516 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 9:
6760 divided by 855 is 7 with a remainder of 775.
Put 7 as the next digit of the answer. 
Result so far: 61578.7
Deduct 5985 from 6760 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Advancing to step 10:
If we divide 7750 by 855, we get 9 and a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 61578.79
If we subtract 7695 from 7750, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
If we divide 550 by 855, we get 0 and a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 61578.79
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 12:
The number 855 fits into 5500 6 times, leaving a remainder of 370.
The next digit of our result is 6. 
Result so far: 61578.7906
If we subtract 5130 from 5500, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 13:
The number 855 fits into 3700 4 times, leaving a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 61578.79064
Subtract 3420 from 3700 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
When dividing 2800 by 855, we get 3 with a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 61578.790643
Subtracting 2565 from 2800 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 15:
The number 855 fits into 2350 2 times, leaving a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 61578.7906432
Deduct 1710 from 2350 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 16:
The number 855 fits into 6400 7 times, leaving a remainder of 415.
Use 7 as the next digit of our solution. 
Result so far: 61578.79064327
Subtract 5985 from 6400 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

The final result is 61578.79064327 with a remainder of 4.15e-07.
