378524 divided by 80 
We want to figure out the number of times 378524 can be divided by 80.

Going ahead to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 80

Step 2:
80 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 80

Step 3:
If we divide 378 by 80, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 320 from 378 to get 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 80

Moving on to step 4:
The number 80 fits into 585 7 times, leaving a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 560 from 585 and we're left with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 80

Moving on to step 5:
252 divided by 80 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 473.0
If we take 240 away from 252, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 80

Let's proceed to step 6:
80 goes into 124 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 4731.0
If we take 80 away from 124, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
If we divide 440 by 80, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4731.5
If we take 400 away from 440, we end up 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.

Going ahead to step 8:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4731.55
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.

The quotient of the division is 4731.55, and the remainder is 0.0.
