726789 ÷ 8 
We want to figure out the number of times 726789 can be divided by 8.

Moving on to step 1:
8 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
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 8

Going ahead to step 2:
When dividing 72 by 8, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 0 after subtracting 72 from 72.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 8

Step 3:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 8

Let's proceed to step 4:
If we divide 67 by 8, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 908.0
Subtract 64 from 67 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 8

On to step 5:
If we divide 38 by 8, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 9084.0
Subtracting 32 from 38 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 8

Going ahead to step 6:
8 can be fit into 69 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 90848.0
Deduct 64 from 69 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 8 fits into 50 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 90848.6
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 90848.62
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 90848.625
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 90848.625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 90848.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 90848.625, with a leftover of 0.0.
