We're dividing 90341540 by 8 
We want to figure out the number of times 90341540 can be divided by 8.

Let's proceed to step 1:
8 can be fit into 9 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 8 from 9 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 8

Moving on to step 2:
10 divided by 8 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 8 from 10 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Advancing to step 3:
8 goes into 23 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 16 from 23 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 8

Step 4:
If we divide 74 by 8, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 1129.0
The remainder is 2 after subtracting 72 from 74.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 8

Moving on to step 5:
21 divided by 8 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 11292.0
Subtracting 16 from 21 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 8

On to step 6:
The number 8 fits into 55 6 times, leaving a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 112926.0
If we take 48 away from 55, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 8

Let's proceed to step 7:
When dividing 74 by 8, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1129269.0
The remainder is 2 after subtracting 72 from 74.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

On to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 11292692.0
If we subtract 16 from 20, 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.

On to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11292692.5
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:
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: 11292692.5
Deduct 0 from 0 and we're left 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.

Going ahead to step 11:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11292692.5
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.

The final result is 11292692.5 with a remainder of 0.0.
