9 divided by 729 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 729

On to step 2:
729 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 729

Step 3:
917 divided by 729 is 1 with a remainder of 188.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 729 away from 917, we end up with 188.
Fetch the next digit (6) from the dividend, attach it to 188 and continue: 1886 / 729

Advancing to step 4:
When dividing 1886 by 729, we get 2 with a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1458 from 1886 and we're left with 428.
Include the next digit (9) from the dividend after 428, then repeat: 4289 / 729

Advancing to step 5:
If we divide 4289 by 729, we get 5 and a remainder of 644.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 3645 from 4289, we get 644.
Fetch the next digit (0) from the dividend, attach it to 644 and continue: 6440 / 729

Advancing to step 6:
6440 divided by 729 is 8 with a remainder of 608.
The next digit of our result is 8. 
Result so far: 1258.0
Subtracting 5832 from 6440 leaves us with 608.
Append the next digit (8) from the dividend to 608 and continue with: 6088 / 729

Going ahead to step 7:
729 can be fit into 6088 8 times, resulting in a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 12588.0
Subtracting 5832 from 6088 leaves us with 256.
Append the next digit (3) from the dividend to 256 and continue with: 2563 / 729

Step 8:
If we divide 2563 by 729, we get 3 and a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 125883.0
Deduct 2187 from 2563 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 9:
If we divide 3760 by 729, we get 5 and a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 125883.5
Subtracting 3645 from 3760 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
If we divide 1150 by 729, we get 1 and a remainder of 421.
Put 1 as the next digit of the answer. 
Result so far: 125883.51
Deduct 729 from 1150 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 11:
729 goes into 4210 5 times with a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 125883.515
If we subtract 3645 from 4210, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

On to step 12:
729 goes into 5650 7 times with a remainder of 547.
Put 7 as the next digit of the answer. 
Result so far: 125883.5157
Deduct 5103 from 5650 and we're left with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Advancing to step 13:
When dividing 5470 by 729, we get 7 with a remainder of 367.
The number 7 becomes the next digit in our result. 
Result so far: 125883.51577
If we subtract 5103 from 5470, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The final outcome is 125883.51577, with a leftover of 0.000367.
