765139 ÷ 8 
We want to figure out the number of times 765139 can be divided by 8.

Moving on to step 1:
If we divide 7 by 8, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 8

On to step 2:
76 divided by 8 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 72 from 76 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 8

Moving on to step 3:
8 goes into 45 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 40 from 45 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Going ahead to step 4:
If we divide 51 by 8, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 956.0
The remainder is 3 after subtracting 48 from 51.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 8

Advancing to step 5:
When dividing 33 by 8, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 9564.0
Deduct 32 from 33 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 8

Let's proceed to step 6:
When dividing 19 by 8, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 95642.0
Subtracting 16 from 19 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 95642.3
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
8 goes into 60 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 95642.37
If we subtract 56 from 60, we 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.

Advancing to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 95642.375
If we subtract 40 from 40, 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.

Let's proceed to step 10:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 95642.375
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.

Going ahead to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 95642.375
If we take 0 away from 0, we end up with 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 95642.375, with a leftover of 0.0.
