391609 divided by 8 
We want to divide 391609 by 8.

Moving on to step 1:
3 divided by 8 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 8

Going ahead to step 2:
The number 8 fits into 39 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 32 from 39 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 8

Advancing to step 3:
8 goes into 71 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 64 from 71 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

Moving on to step 4:
8 goes into 76 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
Subtracting 72 from 76 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 8

Let's proceed to step 5:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 4895.0
Subtracting 40 from 40 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 8

Moving on to step 6:
The number 8 fits into 9 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 48951.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 8 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 48951.1
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 8, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 48951.12
Subtracting 16 from 20 leaves us 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.

On to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 48951.125
Subtract 40 from 40 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.

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: 48951.125
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.

Advancing to step 11:
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: 48951.125
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 quotient of the division is 48951.125, and the remainder is 0.0.
