We divide 67390987 by 729
We want to figure out the number of times 67390987 can be divided by 729.

Let's proceed to step 1:
If we divide 6 by 729, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 729

On to step 2:
If we divide 67 by 729, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 729

Step 3:
The number 729 fits into 673 0 times, leaving a remainder of 673.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 673, we get 673.
Grab the next digit (9) from the dividend, add it to 673, then carry on: 6739 / 729

On to step 4:
6739 divided by 729 is 9 with a remainder of 178.
The next digit of our result is 9. 
Result so far: 9.0
If we take 6561 away from 6739, we end up with 178.
Bring next digit (0) of the dividend behind the 178 and repeat the process: 1780 / 729

Going ahead to step 5:
The number 729 fits into 1780 2 times, leaving a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we subtract 1458 from 1780, we get 322.
Grab the next digit (9) from the dividend, add it to 322, then carry on: 3229 / 729

Advancing to step 6:
3229 divided by 729 is 4 with a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 924.0
Subtract 2916 from 3229 to get 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 729

Advancing to step 7:
If we divide 3138 by 729, we get 4 and a remainder of 222.
Put 4 as the next digit of the answer. 
Result so far: 9244.0
Subtracting 2916 from 3138 leaves us with 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 729

Let's proceed to step 8:
2227 divided by 729 is 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 92443.0
The remainder is 40 after subtracting 2187 from 2227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 729 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 92443.0
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
If we divide 4000 by 729, we get 5 and a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 92443.05
If we subtract 3645 from 4000, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 11:
The number 729 fits into 3550 4 times, leaving a remainder of 634.
Put 4 as the next digit of the answer. 
Result so far: 92443.054
Subtracting 2916 from 3550 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 12:
If we divide 6340 by 729, we get 8 and a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 92443.0548
Subtracting 5832 from 6340 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 13:
729 can be fit into 5080 6 times, resulting in a remainder of 706.
The number 6 becomes the next digit in our result. 
Result so far: 92443.05486
Deduct 4374 from 5080 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Advancing to step 14:
If we divide 7060 by 729, we get 9 and a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 92443.054869
If we take 6561 away from 7060, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 15:
If we divide 4990 by 729, we get 6 and a remainder of 616.
Put 6 as the next digit of the answer. 
Result so far: 92443.0548696
Deduct 4374 from 4990 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 16:
729 goes into 6160 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 92443.05486968
Subtracting 5832 from 6160 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 92443.05486968 with a balance of 3.28e-07.
