360998 ÷ 80 
Our goal is to divide 360998 by 80.

Step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 80

Let's proceed to step 2:
80 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 80

Step 3:
When dividing 360 by 80, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 320 from 360 and we're left with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 80

On to step 4:
409 divided by 80 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 9 after subtracting 400 from 409.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 80

Going ahead to step 5:
The number 80 fits into 99 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Subtracting 80 from 99 leaves us with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 80

Advancing to step 6:
80 can be fit into 198 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 4512.0
Subtracting 160 from 198 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
When dividing 380 by 80, we get 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 4512.4
If we take 320 away from 380, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 4512.47
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4512.475
Subtract 400 from 400 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.

Let's proceed to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4512.475
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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4512.475
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.

After the division, we end up with 4512.475 and a remainder of 0.0.
