We look at the division of 70503712 by 8 
We're looking to find how many times 8 goes into 70503712.

Advancing to step 1:
7 divided by 8 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 8

Step 2:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 64 from 70, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 8

Going ahead to step 3:
When dividing 65 by 8, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 64 from 65, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 8

Moving on to step 4:
8 can be fit into 10 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 881.0
Subtracting 8 from 10 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Moving on to step 5:
8 goes into 23 2 times with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 8812.0
If we take 16 away from 23, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 8

Advancing to step 6:
77 divided by 8 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 88129.0
Deduct 72 from 77 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 8

Let's proceed to step 7:
When dividing 51 by 8, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 881296.0
Subtracting 48 from 51 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 8

Step 8:
8 goes into 32 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 8812964.0
Subtract 32 from 32 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.

Advancing to step 9:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8812964.0
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.

On to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8812964.0
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.

In conclusion, the division gives 8812964.0 with a balance of 0.0.
