672752 divided by 21 
We're looking to find how many times 21 goes into 672752.

On to step 1:
21 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Going ahead to step 2:
21 goes into 67 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 63 from 67, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 21

Moving on to step 3:
21 goes into 42 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 42 from 42 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 21

Going ahead to step 4:
21 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 320.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

Going ahead to step 5:
If we divide 75 by 21, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 3203.0
Deduct 63 from 75 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 21

Moving on to step 6:
The number 21 fits into 122 5 times, leaving a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 32035.0
If we take 105 away from 122, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 32035.8
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.

Step 8:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 32035.8
Subtracting 0 from 20 leaves us with 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 9:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 32035.809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 32035.8095
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.

Let's proceed to step 11:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 32035.80952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 32035.809523
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.

Let's proceed to step 13:
170 divided by 21 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 32035.8095238
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.

On to step 14:
21 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 32035.8095238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 32035.8095238 with a remainder of 2e-08.
