We look at the division of 21521642 by 922 
We want to divide 21521642 by 922.

Moving on to step 1:
2 divided by 922 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 922

Step 2:
922 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 922

Advancing to step 3:
If we divide 215 by 922, we get 0 and a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Take the next digit (2) from the dividend and append it to 215, then repeat: 2152 / 922

Advancing to step 4:
The number 922 fits into 2152 2 times, leaving a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1844 away from 2152, we end up with 308.
Append the next digit (1) from the dividend to 308 and continue with: 3081 / 922

Going ahead to step 5:
3081 divided by 922 is 3 with a remainder of 315.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 2766 from 3081 to get 315.
Fetch the next digit (6) from the dividend, attach it to 315 and continue: 3156 / 922

On to step 6:
922 can be fit into 3156 3 times, resulting in a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we subtract 2766 from 3156, we get 390.
Fetch the next digit (4) from the dividend, attach it to 390 and continue: 3904 / 922

Let's proceed to step 7:
When dividing 3904 by 922, we get 4 with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 2334.0
Subtract 3688 from 3904 to get 216.
Include the next digit (2) from the dividend after 216, then repeat: 2162 / 922

Step 8:
922 goes into 2162 2 times with a remainder of 318.
The next digit of our result is 2. 
Result so far: 23342.0
The remainder is 318 after subtracting 1844 from 2162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
922 goes into 3180 3 times with a remainder of 414.
Write down 3 as next digit of the result. 
Result so far: 23342.3
Deduct 2766 from 3180 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
If we divide 4140 by 922, we get 4 and a remainder of 452.
Use 4 as the next digit of our solution. 
Result so far: 23342.34
The remainder is 452 after subtracting 3688 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 11:
The number 922 fits into 4520 4 times, leaving a remainder of 832.
Put 4 as the next digit of the answer. 
Result so far: 23342.344
If we take 3688 away from 4520, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

After the division, we end up with 23342.344 and a remainder of 0.0832.
