72216629 ÷ 826 
We want to divide 72216629 by 826.

Advancing to step 1:
826 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 826

Going ahead to step 2:
826 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 826

On to step 3:
If we divide 722 by 826, we get 0 and a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 722, we end up with 722.
Fetch the next digit (1) from the dividend, attach it to 722 and continue: 7221 / 826

Moving on to step 4:
7221 divided by 826 is 8 with a remainder of 613.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6608 from 7221, we get 613.
Fetch the next digit (6) from the dividend, attach it to 613 and continue: 6136 / 826

Moving on to step 5:
6136 divided by 826 is 7 with a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtracting 5782 from 6136 leaves us with 354.
Take the next digit (6) from the dividend and append it to 354, then repeat: 3546 / 826

Going ahead to step 6:
3546 divided by 826 is 4 with a remainder of 242.
The next digit of our result is 4. 
Result so far: 874.0
Deduct 3304 from 3546 and we're left with 242.
Take the next digit (2) from the dividend and append it to 242, then repeat: 2422 / 826

On to step 7:
2422 divided by 826 is 2 with a remainder of 770.
The next digit of our result is 2. 
Result so far: 8742.0
If we subtract 1652 from 2422, we get 770.
Include the next digit (9) from the dividend after 770, then repeat: 7709 / 826

Step 8:
When dividing 7709 by 826, we get 9 with a remainder of 275.
Put 9 as the next digit of the answer. 
Result so far: 87429.0
Subtract 7434 from 7709 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
826 can be fit into 2750 3 times, resulting in a remainder of 272.
The number 3 becomes the next digit in our result. 
Result so far: 87429.3
Deduct 2478 from 2750 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
826 can be fit into 2720 3 times, resulting in a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 87429.33
Subtract 2478 from 2720 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 87429.33, with a leftover of 0.242.
