We're dividing 80120560 by 729 
We're looking to find how many times 729 goes into 80120560.

Going ahead to step 1:
If we divide 8 by 729, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 729

Let's proceed to step 2:
729 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 729

Going ahead to step 3:
729 goes into 801 1 times with a remainder of 72.
The next digit of our result is 1. 
Result so far: 1.0
If we take 729 away from 801, we end up with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 729

Moving on to step 4:
If we divide 722 by 729, we get 0 and a remainder of 722.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 722 leaves us with 722.
Grab the next digit (0) from the dividend, add it to 722, then carry on: 7220 / 729

Step 5:
729 goes into 7220 9 times with a remainder of 659.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 6561 from 7220 to get 659.
Include the next digit (5) from the dividend after 659, then repeat: 6595 / 729

Step 6:
If we divide 6595 by 729, we get 9 and a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 1099.0
Deduct 6561 from 6595 and we're left with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 729

Advancing to step 7:
729 goes into 346 0 times with a remainder of 346.
Record the quotient 0 as the next digit in the result. 
Result so far: 10990.0
If we subtract 0 from 346, we get 346.
Bring next digit (0) of the dividend behind the 346 and repeat the process: 3460 / 729

Step 8:
The number 729 fits into 3460 4 times, leaving a remainder of 544.
The next digit of our result is 4. 
Result so far: 109904.0
If we take 2916 away from 3460, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 9:
729 can be fit into 5440 7 times, resulting in a remainder of 337.
Write down 7 as next digit of the result. 
Result so far: 109904.7
Subtracting 5103 from 5440 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 10:
The number 729 fits into 3370 4 times, leaving a remainder of 454.
Put 4 as the next digit of the answer. 
Result so far: 109904.74
Subtracting 2916 from 3370 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 11:
If we divide 4540 by 729, we get 6 and a remainder of 166.
Put 6 as the next digit of the answer. 
Result so far: 109904.746
Deduct 4374 from 4540 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 12:
729 can be fit into 1660 2 times, resulting in a remainder of 202.
Use 2 as the next digit of our solution. 
Result so far: 109904.7462
If we take 1458 away from 1660, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 13:
When dividing 2020 by 729, we get 2 with a remainder of 562.
The next digit of our result is 2. 
Result so far: 109904.74622
If we subtract 1458 from 2020, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

After the division, we end up with 109904.74622 and a remainder of 0.000562.
