We divide 667214 by 21
We're looking to find how many times 21 goes into 667214.

Moving on to step 1:
6 divided by 21 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 21

On to step 2:
21 can be fit into 66 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 66, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 21

Advancing to step 3:
21 can be fit into 37 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 21 from 37 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 21

Advancing to step 4:
If we divide 162 by 21, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 317.0
If we take 147 away from 162, we end up with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 21

On to step 5:
21 can be fit into 151 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3177.0
If we take 147 away from 151, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 21

Let's proceed to step 6:
If we divide 44 by 21, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 31772.0
The remainder is 2 after subtracting 42 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 31772.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 31772.09
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 31772.095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 31772.0952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 31772.09523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 31772.095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 31772.095238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 31772.09523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 31772.09523809 and a remainder of 1.1e-08.
