364978 ÷ 80 
We want to divide 364978 by 80.

Step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 80

Advancing to step 2:
80 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 80

Let's proceed to step 3:
If we divide 364 by 80, we get 4 and a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 320 from 364 and we're left with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 80

Going ahead to step 4:
449 divided by 80 is 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 49 after subtracting 400 from 449.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 80

Moving on to step 5:
80 goes into 497 6 times with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
Deduct 480 from 497 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 80

Let's proceed to step 6:
178 divided by 80 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4562.0
Deduct 160 from 178 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 80, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 4562.2
Subtracting 160 from 180 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 4562.22
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 4562.22 with a remainder of 0.04.
