We look at the division of 314547 by 21 
We want to divide 314547 by 21.

Step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 21

Going ahead to step 2:
When dividing 31 by 21, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 31 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 21

Advancing to step 3:
If we divide 104 by 21, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 20 after subtracting 84 from 104.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 21

Moving on to step 4:
If we divide 205 by 21, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we subtract 189 from 205, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 21

Let's proceed to step 5:
When dividing 164 by 21, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 1497.0
If we subtract 147 from 164, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 21

Going ahead to step 6:
The number 21 fits into 177 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 14978.0
Subtract 168 from 177 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
21 goes into 90 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14978.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 21, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14978.42
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
180 divided by 21 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 14978.428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 21 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 14978.4285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 14978.42857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 14978.428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 14978.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 14978.42857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 14978.42857142, with a leftover of 1.8e-08.
