We look at the division of 78135061 by 729 
We're looking to find how many times 729 goes into 78135061.

Going ahead to step 1:
729 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 729

Going ahead to step 2:
729 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 729

Step 3:
The number 729 fits into 781 1 times, leaving a remainder of 52.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 729 from 781 and we're left with 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 729

On to step 4:
729 goes into 523 0 times with a remainder of 523.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 523, we get 523.
Grab the next digit (5) from the dividend, add it to 523, then carry on: 5235 / 729

Moving on to step 5:
5235 divided by 729 is 7 with a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 5103 from 5235 and we're left with 132.
Grab the next digit (0) from the dividend, add it to 132, then carry on: 1320 / 729

Let's proceed to step 6:
1320 divided by 729 is 1 with a remainder of 591.
The next digit of our result is 1. 
Result so far: 1071.0
Subtract 729 from 1320 to get 591.
Bring next digit (6) of the dividend behind the 591 and repeat the process: 5916 / 729

Step 7:
If we divide 5916 by 729, we get 8 and a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 10718.0
The remainder is 84 after subtracting 5832 from 5916.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 729

Advancing to step 8:
If we divide 841 by 729, we get 1 and a remainder of 112.
The next digit of our result is 1. 
Result so far: 107181.0
If we subtract 729 from 841, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
1120 divided by 729 is 1 with a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 107181.1
Subtract 729 from 1120 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 10:
3910 divided by 729 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 107181.15
Deduct 3645 from 3910 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 11:
729 can be fit into 2650 3 times, resulting in a remainder of 463.
Record the quotient 3 as the next digit in the result. 
Result so far: 107181.153
Subtract 2187 from 2650 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 12:
The number 729 fits into 4630 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 107181.1536
Subtract 4374 from 4630 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
2560 divided by 729 is 3 with a remainder of 373.
Write down 3 as next digit of the result. 
Result so far: 107181.15363
Deduct 2187 from 2560 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 14:
729 goes into 3730 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 107181.153635
The remainder is 85 after subtracting 3645 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 15:
When dividing 850 by 729, we get 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 107181.1536351
Subtract 729 from 850 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 16:
729 can be fit into 1210 1 times, resulting in a remainder of 481.
Put 1 as the next digit of the answer. 
Result so far: 107181.15363511
Subtract 729 from 1210 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

The final outcome is 107181.15363511, with a leftover of 4.81e-07.
