We look at the division of 904609 by 8 
We want to figure out the number of times 904609 can be divided by 8.

Going ahead to step 1:
8 goes into 9 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
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

Going ahead to step 2:
10 divided by 8 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 2 after subtracting 8 from 10.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

Going ahead to step 3:
The number 8 fits into 24 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we subtract 24 from 24, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 8

Going ahead to step 4:
6 divided by 8 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 1130.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 8

Going ahead to step 5:
If we divide 60 by 8, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 11307.0
The remainder is 4 after subtracting 56 from 60.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 8

On to step 6:
8 goes into 49 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 113076.0
Subtract 48 from 49 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 113076.1
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 113076.12
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:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 113076.125
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.

On 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: 113076.125
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.

On to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 113076.125
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.

The quotient of the division is 113076.125, and the remainder is 0.0.
