We're dividing 14976964 by 21 
We're looking to find how many times 21 goes into 14976964.

Going ahead to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Moving on to step 2:
14 divided by 21 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 21

Moving on to step 3:
21 goes into 149 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 147 from 149 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

On to step 4:
21 goes into 27 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we take 21 away from 27, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 21

Advancing to step 5:
The number 21 fits into 66 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 713.0
If we take 63 away from 66, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 21

Going ahead to step 6:
The number 21 fits into 39 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 7131.0
Subtract 21 from 39 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 21

On to step 7:
21 goes into 186 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 71318.0
If we subtract 168 from 186, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 21

Going ahead to step 8:
184 divided by 21 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 713188.0
The remainder is 16 after subtracting 168 from 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 21, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 713188.7
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 713188.76
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 713188.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 713188.7619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 713188.7619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 713188.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 713188.7619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 16:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 713188.76190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 713188.76190476 with a remaining 4e-09.
