We divide 90916950 by 8
We want to divide 90916950 by 8.

Going ahead to step 1:
If we divide 9 by 8, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Advancing to step 2:
When dividing 10 by 8, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 2 after subtracting 8 from 10.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 8

Advancing to step 3:
29 divided by 8 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 113.0
The remainder is 5 after subtracting 24 from 29.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Moving on to step 4:
8 goes into 51 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 1136.0
Deduct 48 from 51 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 8

Let's proceed to step 5:
The number 8 fits into 36 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 11364.0
The remainder is 4 after subtracting 32 from 36.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 8

Going ahead to step 6:
49 divided by 8 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 113646.0
If we take 48 away from 49, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 8

Step 7:
8 can be fit into 15 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1136461.0
Subtract 8 from 15 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 8

Moving on to step 8:
If we divide 70 by 8, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 11364618.0
If we take 64 away from 70, we end up 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.

Step 9:
8 goes into 60 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 11364618.7
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.

Step 10:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11364618.75
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.

Advancing to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11364618.75
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 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11364618.75
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 result is 11364618.75 with a remainder of 0.0.
