80620556 ÷ 729 
We want to figure out the number of times 80620556 can be divided by 729.

Step 1:
When dividing 8 by 729, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 729

Going ahead to step 2:
729 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 729

On to step 3:
If we divide 806 by 729, we get 1 and a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 729 from 806, we get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 729

Advancing to step 4:
729 can be fit into 772 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 729 away from 772, we end up with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 729

Advancing to step 5:
If we divide 430 by 729, we get 0 and a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 430 to get 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 729

On to step 6:
729 goes into 4305 5 times with a remainder of 660.
Write down 5 as next digit of the result. 
Result so far: 1105.0
If we take 3645 away from 4305, we end up with 660.
Grab the next digit (5) from the dividend, add it to 660, then carry on: 6605 / 729

Going ahead to step 7:
729 goes into 6605 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 11059.0
The remainder is 44 after subtracting 6561 from 6605.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 729

Advancing to step 8:
The number 729 fits into 446 0 times, leaving a remainder of 446.
Use 0 as the next digit of our solution. 
Result so far: 110590.0
The remainder is 446 after subtracting 0 from 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 9:
When dividing 4460 by 729, we get 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 110590.6
Subtract 4374 from 4460 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
860 divided by 729 is 1 with a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 110590.61
If we take 729 away from 860, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 11:
729 goes into 1310 1 times with a remainder of 581.
The next digit of our result is 1. 
Result so far: 110590.611
If we subtract 729 from 1310, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Our division results in 110590.611 with a remaining 0.0581.
