Let's divide 392289 by 8
We're looking to find how many times 8 goes into 392289.

Going ahead to step 1:
3 divided by 8 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 8

Let's proceed to step 2:
If we divide 39 by 8, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 32 from 39 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 8

Moving on to step 3:
When dividing 72 by 8, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 72 from 72, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 8

Step 4:
8 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 490.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 8

Moving on to step 5:
8 goes into 28 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4903.0
Subtracting 24 from 28 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 8

Advancing to step 6:
The number 8 fits into 49 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 49036.0
If we subtract 48 from 49, we 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:
8 goes into 10 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 49036.1
If we take 8 away from 10, we end up 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.

On to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 49036.12
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.

Step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49036.125
If we take 40 away from 40, 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.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49036.125
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.

Advancing to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49036.125
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.

After the division, we end up with 49036.125 and a remainder of 0.0.
