On to step 7:
If we divide 3 by 8, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 909000.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 8

On to step 8:
8 goes into 35 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 9090004.0
If we subtract 32 from 35, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 8 fits into 30 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 9090004.3
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.

Let's proceed to step 10:
8 goes into 60 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 9090004.37
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.

Advancing to step 11:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9090004.375
The remainder is 0 after subtracting 40 from 40.
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 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9090004.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9090004.375
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.

Our division results in 9090004.375 with a remaining 0.0.
