Let's divide 975139 by 8
We want to figure out the number of times 975139 can be divided by 8.

Step 1:
When dividing 9 by 8, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 8

Moving on to step 2:
8 can be fit into 17 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 16 from 17, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 8

Moving on to step 3:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 8 from 15 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 8

Advancing to step 4:
8 goes into 71 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 1218.0
Subtracting 64 from 71 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 8

Advancing to step 5:
The number 8 fits into 73 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 12189.0
Subtracting 72 from 73 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 8

Moving on to step 6:
When dividing 19 by 8, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 121892.0
Deduct 16 from 19 and we're left 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.

Step 7:
30 divided by 8 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 121892.3
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 121892.37
Deduct 56 from 60 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.

Moving on to step 9:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 121892.375
Subtracting 40 from 40 leaves us 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.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 121892.375
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.

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: 121892.375
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.

After the division, we end up with 121892.375 and a remainder of 0.0.
