Let's divide 425922 by 21
We want to divide 425922 by 21.

Step 1:
4 divided by 21 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 21

Let's proceed to step 2:
When dividing 42 by 21, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 42 from 42, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 21

Step 3:
5 divided by 21 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 5, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 21

Step 4:
The number 21 fits into 59 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 202.0
If we subtract 42 from 59, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 21

Let's proceed to step 5:
21 goes into 172 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2028.0
If we subtract 168 from 172, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 21

Going ahead to step 6:
The number 21 fits into 42 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 20282.0
Subtracting 42 from 42 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.

Step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20282.0
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.

On to step 8:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20282.0
If we subtract 0 from 0, we get 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 quotient of the division is 20282.0, and the remainder is 0.0.
