We divide 21722081 by 396
We want to divide 21722081 by 396.

Moving on to step 1:
396 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 396

Going ahead to step 2:
21 divided by 396 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 396

Step 3:
396 goes into 217 0 times with a remainder of 217.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Grab the next digit (2) from the dividend, add it to 217, then carry on: 2172 / 396

Let's proceed to step 4:
If we divide 2172 by 396, we get 5 and a remainder of 192.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1980 from 2172 to get 192.
Include the next digit (2) from the dividend after 192, then repeat: 1922 / 396

Going ahead to step 5:
396 can be fit into 1922 4 times, resulting in a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 338 after subtracting 1584 from 1922.
Include the next digit (0) from the dividend after 338, then repeat: 3380 / 396

Going ahead to step 6:
The number 396 fits into 3380 8 times, leaving a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 548.0
The remainder is 212 after subtracting 3168 from 3380.
Grab the next digit (8) from the dividend, add it to 212, then carry on: 2128 / 396

Let's proceed to step 7:
2128 divided by 396 is 5 with a remainder of 148.
Use 5 as the next digit of our solution. 
Result so far: 5485.0
Deduct 1980 from 2128 and we're left with 148.
Append the next digit (1) from the dividend to 148 and continue with: 1481 / 396

Step 8:
396 goes into 1481 3 times with a remainder of 293.
Use 3 as the next digit of our solution. 
Result so far: 54853.0
Deduct 1188 from 1481 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 9:
396 goes into 2930 7 times with a remainder of 158.
The next digit of our result is 7. 
Result so far: 54853.7
If we subtract 2772 from 2930, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
The number 396 fits into 1580 3 times, leaving a remainder of 392.
Record the quotient 3 as the next digit in the result. 
Result so far: 54853.73
If we take 1188 away from 1580, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 11:
When dividing 3920 by 396, we get 9 with a remainder of 356.
Record the quotient 9 as the next digit in the result. 
Result so far: 54853.739
If we take 3564 away from 3920, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 12:
If we divide 3560 by 396, we get 8 and a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 54853.7398
Subtracting 3168 from 3560 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 13:
396 goes into 3920 9 times with a remainder of 356.
Record the quotient 9 as the next digit in the result. 
Result so far: 54853.73989
Subtract 3564 from 3920 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 14:
396 goes into 3560 8 times with a remainder of 392.
The next digit of our result is 8. 
Result so far: 54853.739898
Subtracting 3168 from 3560 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 15:
The number 396 fits into 3920 9 times, leaving a remainder of 356.
Write down 9 as next digit of the result. 
Result so far: 54853.7398989
If we subtract 3564 from 3920, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 16:
The number 396 fits into 3560 8 times, leaving a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 54853.73989898
Subtract 3168 from 3560 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 54853.73989898, with a leftover of 3.92e-07.
