Let's divide 998642 by 8
We're looking to find how many times 8 goes into 998642.

Advancing to step 1:
8 goes into 9 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 8

Going ahead to step 2:
8 goes into 19 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 3 after subtracting 16 from 19.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 8

Let's proceed to step 3:
38 divided by 8 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtracting 32 from 38 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 8

Let's proceed to step 4:
66 divided by 8 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1248.0
Subtract 64 from 66 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 8

Let's proceed to step 5:
24 divided by 8 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 12483.0
If we take 24 away from 24, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 8

Going ahead to step 6:
The number 8 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 124830.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 124830.2
Deduct 16 from 20 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 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 124830.25
Deduct 40 from 40 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.

Step 9:
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: 124830.25
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.

Step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 124830.25
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.

In conclusion, the division gives 124830.25 with a balance of 0.0.
