21879480 ÷ 722 
Let's see how many times 722 fits into 21879480.

Step 1:
722 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 722

Let's proceed to step 2:
When dividing 21 by 722, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 722

Step 3:
218 divided by 722 is 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Bring next digit (7) of the dividend behind the 218 and repeat the process: 2187 / 722

Moving on to step 4:
When dividing 2187 by 722, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2166 from 2187 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 722

Let's proceed to step 5:
When dividing 219 by 722, we get 0 with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 219 and we're left with 219.
Include the next digit (4) from the dividend after 219, then repeat: 2194 / 722

Step 6:
If we divide 2194 by 722, we get 3 and a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we subtract 2166 from 2194, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 722

Let's proceed to step 7:
The number 722 fits into 288 0 times, leaving a remainder of 288.
The next digit of our result is 0. 
Result so far: 3030.0
Subtracting 0 from 288 leaves us with 288.
Fetch the next digit (0) from the dividend, attach it to 288 and continue: 2880 / 722

Step 8:
When dividing 2880 by 722, we get 3 with a remainder of 714.
Record the quotient 3 as the next digit in the result. 
Result so far: 30303.0
If we take 2166 away from 2880, we end up with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 9:
7140 divided by 722 is 9 with a remainder of 642.
The number 9 becomes the next digit in our result. 
Result so far: 30303.9
If we take 6498 away from 7140, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Moving on to step 10:
If we divide 6420 by 722, we get 8 and a remainder of 644.
Put 8 as the next digit of the answer. 
Result so far: 30303.98
Deduct 5776 from 6420 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 11:
When dividing 6440 by 722, we get 8 with a remainder of 664.
Put 8 as the next digit of the answer. 
Result so far: 30303.988
If we subtract 5776 from 6440, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

The final outcome is 30303.988, with a leftover of 0.0664.
