We're dividing 361815 by 80 
Our goal is to divide 361815 by 80.

On to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 80

Advancing to step 2:
When dividing 36 by 80, we get 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 80

On to step 3:
The number 80 fits into 361 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 320 from 361, we get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 80

Step 4:
418 divided by 80 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 400 from 418 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 80

Advancing to step 5:
The number 80 fits into 181 2 times, leaving a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 452.0
Subtracting 160 from 181 leaves us with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 80

Moving on to step 6:
215 divided by 80 is 2 with a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 4522.0
Deduct 160 from 215 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
80 goes into 550 6 times with a remainder of 70.
The next digit of our result is 6. 
Result so far: 4522.6
Subtracting 480 from 550 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 4522.68
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 4522.687
Subtract 560 from 600 to get 40.
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 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4522.6875
Deduct 400 from 400 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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4522.6875
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.

On to step 12:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4522.6875
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.

The quotient of the division is 4522.6875, and the remainder is 0.0.
