21983372 ÷ 983 
Our goal is to divide 21983372 by 983.

Moving on to step 1:
2 divided by 983 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 983

On to step 2:
983 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 983

Going ahead to step 3:
When dividing 219 by 983, we get 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Take the next digit (8) from the dividend and append it to 219, then repeat: 2198 / 983

Going ahead to step 4:
983 goes into 2198 2 times with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1966 from 2198 to get 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 983

On to step 5:
983 goes into 2323 2 times with a remainder of 357.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 1966 from 2323 and we're left with 357.
Fetch the next digit (3) from the dividend, attach it to 357 and continue: 3573 / 983

Step 6:
983 goes into 3573 3 times with a remainder of 624.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Subtract 2949 from 3573 to get 624.
Include the next digit (7) from the dividend after 624, then repeat: 6247 / 983

Let's proceed to step 7:
If we divide 6247 by 983, we get 6 and a remainder of 349.
The next digit of our result is 6. 
Result so far: 2236.0
If we subtract 5898 from 6247, we get 349.
Fetch the next digit (2) from the dividend, attach it to 349 and continue: 3492 / 983

Step 8:
If we divide 3492 by 983, we get 3 and a remainder of 543.
The next digit of our result is 3. 
Result so far: 22363.0
Subtracting 2949 from 3492 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 9:
When dividing 5430 by 983, we get 5 with a remainder of 515.
The next digit of our result is 5. 
Result so far: 22363.5
The remainder is 515 after subtracting 4915 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 10:
5150 divided by 983 is 5 with a remainder of 235.
The next digit of our result is 5. 
Result so far: 22363.55
Deduct 4915 from 5150 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final outcome is 22363.55, with a leftover of 0.235.
