Let's divide 922538 by 21
We want to figure out the number of times 922538 can be divided by 21.

Step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 21

Let's proceed to step 2:
92 divided by 21 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 84 away from 92, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 21

Moving on to step 3:
When dividing 82 by 21, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 63 from 82 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 21

Moving on to step 4:
21 can be fit into 195 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 439.0
The remainder is 6 after subtracting 189 from 195.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 21

Moving on to step 5:
The number 21 fits into 63 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 4393.0
Subtract 63 from 63 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 21

Step 6:
If we divide 8 by 21, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 43930.0
Subtracting 0 from 8 leaves us 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.

Going ahead to step 7:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 43930.3
The remainder is 17 after subtracting 63 from 80.
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 8:
21 goes into 170 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 43930.38
Subtracting 168 from 170 leaves us 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 9:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 43930.38
If we subtract 0 from 20, we 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.

Let's proceed to step 10:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 43930.3809
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.

Step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 43930.38095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 21, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 43930.380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 43930.3809523
Subtracting 63 from 80 leaves us 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.

Moving on to step 14:
21 goes into 170 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 43930.38095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 43930.38095238, with a leftover of 2e-09.
