21297048 divided by 855 
We're looking to find how many times 855 goes into 21297048.

Let's proceed to step 1:
The number 855 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 855

Step 2:
The number 855 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 855

Let's proceed to step 3:
855 goes into 212 0 times with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Include the next digit (9) from the dividend after 212, then repeat: 2129 / 855

Going ahead to step 4:
855 can be fit into 2129 2 times, resulting in a remainder of 419.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1710 from 2129, we get 419.
Append the next digit (7) from the dividend to 419 and continue with: 4197 / 855

Advancing to step 5:
4197 divided by 855 is 4 with a remainder of 777.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 3420 from 4197 to get 777.
Append the next digit (0) from the dividend to 777 and continue with: 7770 / 855

Going ahead to step 6:
855 can be fit into 7770 9 times, resulting in a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
The remainder is 75 after subtracting 7695 from 7770.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 855

On to step 7:
When dividing 754 by 855, we get 0 with a remainder of 754.
The number 0 becomes the next digit in our result. 
Result so far: 2490.0
Deduct 0 from 754 and we're left with 754.
Append the next digit (8) from the dividend to 754 and continue with: 7548 / 855

Going ahead to step 8:
When dividing 7548 by 855, we get 8 with a remainder of 708.
Put 8 as the next digit of the answer. 
Result so far: 24908.0
If we take 6840 away from 7548, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 9:
855 can be fit into 7080 8 times, resulting in a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 24908.8
If we subtract 6840 from 7080, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
855 goes into 2400 2 times with a remainder of 690.
Record the quotient 2 as the next digit in the result. 
Result so far: 24908.82
If we take 1710 away from 2400, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 11:
The number 855 fits into 6900 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 24908.828
Subtracting 6840 from 6900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 855 fits into 600 0 times, leaving a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 24908.828
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
The number 855 fits into 6000 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 24908.82807
If we subtract 5985 from 6000, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
The number 855 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 24908.82807
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
1500 divided by 855 is 1 with a remainder of 645.
Record the quotient 1 as the next digit in the result. 
Result so far: 24908.8280701
Deduct 855 from 1500 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 16:
If we divide 6450 by 855, we get 7 and a remainder of 465.
Write down 7 as next digit of the result. 
Result so far: 24908.82807017
If we take 5985 away from 6450, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Our division results in 24908.82807017 with a remaining 4.65e-07.
