We look at the division of 509198 by 8 
We want to divide 509198 by 8.

Step 1:
If we divide 5 by 8, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Step 2:
The number 8 fits into 50 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 48 from 50 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 8

Moving on to step 3:
8 can be fit into 29 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 24 from 29, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 8

Let's proceed to step 4:
When dividing 51 by 8, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 636.0
If we take 48 away from 51, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 8

On to step 5:
39 divided by 8 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 6364.0
If we take 32 away from 39, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 8

Going ahead to step 6:
When dividing 78 by 8, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 63649.0
If we take 72 away from 78, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 8, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 63649.7
If we subtract 56 from 60, 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 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 63649.75
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 9:
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: 63649.75
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.

Let's proceed 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: 63649.75
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 63649.75 with a balance of 0.0.
