Let's divide 21728876 by 722
We're looking to find how many times 722 goes into 21728876.

Going ahead to step 1:
722 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 722

Step 2:
722 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 722

Moving on to step 3:
The number 722 fits into 217 0 times, leaving a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 722

Moving on to step 4:
2172 divided by 722 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2166 from 2172 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 722

Let's proceed to step 5:
722 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 722

Advancing to step 6:
722 goes into 688 0 times with a remainder of 688.
The next digit of our result is 0. 
Result so far: 300.0
If we take 0 away from 688, we end up with 688.
Append the next digit (7) from the dividend to 688 and continue with: 6887 / 722

Going ahead to step 7:
6887 divided by 722 is 9 with a remainder of 389.
Record the quotient 9 as the next digit in the result. 
Result so far: 3009.0
Deduct 6498 from 6887 and we're left with 389.
Grab the next digit (6) from the dividend, add it to 389, then carry on: 3896 / 722

Moving on to step 8:
722 goes into 3896 5 times with a remainder of 286.
The next digit of our result is 5. 
Result so far: 30095.0
The remainder is 286 after subtracting 3610 from 3896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 9:
When dividing 2860 by 722, we get 3 with a remainder of 694.
The next digit of our result is 3. 
Result so far: 30095.3
The remainder is 694 after subtracting 2166 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Going ahead to step 10:
If we divide 6940 by 722, we get 9 and a remainder of 442.
Put 9 as the next digit of the answer. 
Result so far: 30095.39
Subtract 6498 from 6940 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 11:
4420 divided by 722 is 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 30095.396
Deduct 4332 from 4420 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
880 divided by 722 is 1 with a remainder of 158.
The next digit of our result is 1. 
Result so far: 30095.3961
If we subtract 722 from 880, 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.

Let's proceed to step 13:
The number 722 fits into 1580 2 times, leaving a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 30095.39612
If we subtract 1444 from 1580, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 14:
722 can be fit into 1360 1 times, resulting in a remainder of 638.
Put 1 as the next digit of the answer. 
Result so far: 30095.396121
The remainder is 638 after subtracting 722 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Moving on to step 15:
722 goes into 6380 8 times with a remainder of 604.
Put 8 as the next digit of the answer. 
Result so far: 30095.3961218
Subtract 5776 from 6380 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 16:
When dividing 6040 by 722, we get 8 with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 30095.39612188
Subtract 5776 from 6040 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final result is 30095.39612188 with a remainder of 2.64e-07.
