We divide 20700840 by 855
We want to figure out the number of times 20700840 can be divided by 855.

Advancing to step 1:
855 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 855

On to step 2:
20 divided by 855 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 855

Going ahead to step 3:
207 divided by 855 is 0 with a remainder of 207.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Take the next digit (0) from the dividend and append it to 207, then repeat: 2070 / 855

Let's proceed to step 4:
855 goes into 2070 2 times with a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1710 from 2070 to get 360.
Append the next digit (0) from the dividend to 360 and continue with: 3600 / 855

Step 5:
The number 855 fits into 3600 4 times, leaving a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 3420 from 3600 to get 180.
Bring next digit (8) of the dividend behind the 180 and repeat the process: 1808 / 855

Step 6:
When dividing 1808 by 855, we get 2 with a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Subtracting 1710 from 1808 leaves us with 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 855

Advancing to step 7:
855 can be fit into 984 1 times, resulting in a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 2421.0
Subtracting 855 from 984 leaves us with 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 855

Advancing to step 8:
If we divide 1290 by 855, we get 1 and a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 24211.0
Subtract 855 from 1290 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 9:
If we divide 4350 by 855, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 24211.5
If we take 4275 away from 4350, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
The number 855 fits into 750 0 times, leaving a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 24211.5
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
When dividing 7500 by 855, we get 8 with a remainder of 660.
The number 8 becomes the next digit in our result. 
Result so far: 24211.508
If we subtract 6840 from 7500, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 12:
The number 855 fits into 6600 7 times, leaving a remainder of 615.
The number 7 becomes the next digit in our result. 
Result so far: 24211.5087
Subtracting 5985 from 6600 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 13:
855 can be fit into 6150 7 times, resulting in a remainder of 165.
Write down 7 as next digit of the result. 
Result so far: 24211.50877
Deduct 5985 from 6150 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Our division results in 24211.50877 with a remaining 0.000165.
