We're dividing 72968172 by 8 
Let's see how many times 8 fits into 72968172.

Step 1:
The number 8 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 8

Let's proceed to step 2:
When dividing 72 by 8, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 72 from 72 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 8

Step 3:
9 divided by 8 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 8

Let's proceed to step 4:
8 can be fit into 16 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 912.0
The remainder is 0 after subtracting 16 from 16.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 8

Let's proceed to step 5:
If we divide 8 by 8, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 9121.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 8

Step 6:
8 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 91210.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 8

On to step 7:
8 can be fit into 17 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 912102.0
If we take 16 away from 17, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Advancing to step 8:
If we divide 12 by 8, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 9121021.0
Subtract 8 from 12 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to 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: 9121021.5
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:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9121021.5
If we subtract 0 from 0, we 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.

Step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9121021.5
If we subtract 0 from 0, we 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.

The final outcome is 9121021.5, with a leftover of 0.0.
