378908 ÷ 80 
We want to figure out the number of times 378908 can be divided by 80.

Step 1:
3 divided by 80 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 80

Moving on to step 2:
When dividing 37 by 80, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 80

Going ahead to step 3:
80 goes into 378 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 320 from 378 and we're left with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 80

Step 4:
When dividing 589 by 80, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 29 after subtracting 560 from 589.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 80

On to step 5:
80 can be fit into 290 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 473.0
Subtract 240 from 290 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 80

Step 6:
80 goes into 508 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 4736.0
The remainder is 28 after subtracting 480 from 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
80 goes into 280 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 4736.3
If we take 240 away from 280, 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.

On to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4736.35
If we subtract 400 from 400, we 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.

Advancing to step 9:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4736.35
Deduct 0 from 0 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 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4736.35
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4736.35 with a remaining 0.0.
