We look at the division of 830412 by 8 
We want to figure out the number of times 830412 can be divided by 8.

Advancing to step 1:
8 goes into 8 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 8

Let's proceed to step 2:
The number 8 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 8

Going ahead to step 3:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 24 from 30 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 8

Advancing to step 4:
64 divided by 8 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
If we take 64 away from 64, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 8

Advancing to step 5:
8 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10380.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Going ahead to step 6:
When dividing 12 by 8, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 103801.0
Deduct 8 from 12 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.

Step 7:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 103801.5
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.

Moving on to step 8:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 103801.5
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.

Advancing to step 9:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 103801.5
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.

After the division, we end up with 103801.5 and a remainder of 0.0.
