We're dividing 31235007 by 729 
We want to figure out the number of times 31235007 can be divided by 729.

Going ahead to step 1:
If we divide 3 by 729, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 729

Step 2:
729 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 729

Going ahead to step 3:
729 can be fit into 312 0 times, resulting in a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 312 leaves us with 312.
Grab the next digit (3) from the dividend, add it to 312, then carry on: 3123 / 729

On to step 4:
The number 729 fits into 3123 4 times, leaving a remainder of 207.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2916 away from 3123, we end up with 207.
Fetch the next digit (5) from the dividend, attach it to 207 and continue: 2075 / 729

Step 5:
The number 729 fits into 2075 2 times, leaving a remainder of 617.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 1458 from 2075 to get 617.
Grab the next digit (0) from the dividend, add it to 617, then carry on: 6170 / 729

Advancing to step 6:
729 goes into 6170 8 times with a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Deduct 5832 from 6170 and we're left with 338.
Append the next digit (0) from the dividend to 338 and continue with: 3380 / 729

Moving on to step 7:
729 goes into 3380 4 times with a remainder of 464.
Write down 4 as next digit of the result. 
Result so far: 4284.0
Deduct 2916 from 3380 and we're left with 464.
Include the next digit (7) from the dividend after 464, then repeat: 4647 / 729

On to step 8:
If we divide 4647 by 729, we get 6 and a remainder of 273.
Record the quotient 6 as the next digit in the result. 
Result so far: 42846.0
If we take 4374 away from 4647, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 9:
If we divide 2730 by 729, we get 3 and a remainder of 543.
Use 3 as the next digit of our solution. 
Result so far: 42846.3
The remainder is 543 after subtracting 2187 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 10:
729 goes into 5430 7 times with a remainder of 327.
Write down 7 as next digit of the result. 
Result so far: 42846.37
Deduct 5103 from 5430 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 11:
3270 divided by 729 is 4 with a remainder of 354.
Put 4 as the next digit of the answer. 
Result so far: 42846.374
Subtract 2916 from 3270 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 12:
729 can be fit into 3540 4 times, resulting in a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 42846.3744
If we take 2916 away from 3540, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

After the division, we end up with 42846.3744 and a remainder of 0.00624.
