We're dividing 104398 by 9 
We want to figure out the number of times 104398 can be divided by 9.

Let's proceed to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 9

On to step 2:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 9 from 10, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 9

Advancing to step 3:
9 goes into 14 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 9 from 14, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 9

On to step 4:
53 divided by 9 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 45 from 53 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 9

Let's proceed to step 5:
When dividing 89 by 9, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 1159.0
Deduct 81 from 89 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 9

Let's proceed to step 6:
9 goes into 88 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 11599.0
The remainder is 7 after subtracting 81 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 9, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 11599.7
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 11599.77
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 11599.77, with a leftover of 0.007.
