72920181 ÷ 820 
Let's see how many times 820 fits into 72920181.

Step 1:
If we divide 7 by 820, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 820

Moving on to step 2:
The number 820 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 820

Going ahead to step 3:
820 goes into 729 0 times with a remainder of 729.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 729 and we're left with 729.
Include the next digit (2) from the dividend after 729, then repeat: 7292 / 820

Going ahead to step 4:
7292 divided by 820 is 8 with a remainder of 732.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6560 from 7292 to get 732.
Take the next digit (0) from the dividend and append it to 732, then repeat: 7320 / 820

Going ahead to step 5:
820 can be fit into 7320 8 times, resulting in a remainder of 760.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 760 after subtracting 6560 from 7320.
Fetch the next digit (1) from the dividend, attach it to 760 and continue: 7601 / 820

Let's proceed to step 6:
When dividing 7601 by 820, we get 9 with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 889.0
Subtracting 7380 from 7601 leaves us with 221.
Take the next digit (8) from the dividend and append it to 221, then repeat: 2218 / 820

On to step 7:
820 can be fit into 2218 2 times, resulting in a remainder of 578.
Use 2 as the next digit of our solution. 
Result so far: 8892.0
The remainder is 578 after subtracting 1640 from 2218.
Take the next digit (1) from the dividend and append it to 578, then repeat: 5781 / 820

Advancing to step 8:
820 goes into 5781 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 88927.0
Subtract 5740 from 5781 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
410 divided by 820 is 0 with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 88927.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
820 can be fit into 4100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 88927.05
If we take 4100 away from 4100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 820, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 88927.05
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
If we divide 0 by 820, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 88927.05
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 88927.05 with a remaining 0.0.
