We look at the division of 314853 by 21 
Our goal is to divide 314853 by 21.

On to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 21

Step 2:
The number 21 fits into 31 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 21 away from 31, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 21

Going ahead to step 3:
When dividing 104 by 21, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 84 from 104 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 21

Going ahead to step 4:
21 goes into 208 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 149.0
If we subtract 189 from 208, we get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 21

Moving on to step 5:
21 goes into 195 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1499.0
If we take 189 away from 195, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 21

On to step 6:
If we divide 63 by 21, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 14993.0
Deduct 63 from 63 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14993.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 21, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14993.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 14993.0 with a remainder of 0.0.
