We're dividing 68402040 by 729 
We want to divide 68402040 by 729.

Going ahead to step 1:
The number 729 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 729

Going ahead to step 2:
The number 729 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 729

Let's proceed to step 3:
When dividing 684 by 729, we get 0 with a remainder of 684.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 684 and we're left with 684.
Append the next digit (0) from the dividend to 684 and continue with: 6840 / 729

Let's proceed to step 4:
The number 729 fits into 6840 9 times, leaving a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 6561 from 6840 leaves us with 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 729

Advancing to step 5:
The number 729 fits into 2792 3 times, leaving a remainder of 605.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
The remainder is 605 after subtracting 2187 from 2792.
Append the next digit (0) from the dividend to 605 and continue with: 6050 / 729

Moving on to step 6:
729 goes into 6050 8 times with a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 938.0
Subtracting 5832 from 6050 leaves us with 218.
Bring next digit (4) of the dividend behind the 218 and repeat the process: 2184 / 729

Let's proceed to step 7:
When dividing 2184 by 729, we get 2 with a remainder of 726.
The next digit of our result is 2. 
Result so far: 9382.0
Subtracting 1458 from 2184 leaves us with 726.
Bring next digit (0) of the dividend behind the 726 and repeat the process: 7260 / 729

Advancing to step 8:
729 goes into 7260 9 times with a remainder of 699.
The number 9 becomes the next digit in our result. 
Result so far: 93829.0
If we take 6561 away from 7260, we end up with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Advancing to step 9:
The number 729 fits into 6990 9 times, leaving a remainder of 429.
Put 9 as the next digit of the answer. 
Result so far: 93829.9
Subtract 6561 from 6990 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 10:
The number 729 fits into 4290 5 times, leaving a remainder of 645.
Put 5 as the next digit of the answer. 
Result so far: 93829.95
If we subtract 3645 from 4290, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 11:
If we divide 6450 by 729, we get 8 and a remainder of 618.
Record the quotient 8 as the next digit in the result. 
Result so far: 93829.958
Subtract 5832 from 6450 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 12:
The number 729 fits into 6180 8 times, leaving a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 93829.9588
If we subtract 5832 from 6180, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final outcome is 93829.9588, with a leftover of 0.00348.
