We divide 378541 by 80
We want to figure out the number of times 378541 can be divided by 80.

Step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 80

Going ahead to step 2:
When dividing 37 by 80, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 80

Advancing to step 3:
80 can be fit into 378 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 320 from 378 and we're left with 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 80

Going ahead to step 4:
The number 80 fits into 585 7 times, leaving a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 560 away from 585, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 80

Let's proceed to step 5:
80 can be fit into 254 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we take 240 away from 254, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 80

On to step 6:
If we divide 141 by 80, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 4731.0
The remainder is 61 after subtracting 80 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
610 divided by 80 is 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 4731.7
If we subtract 560 from 610, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 4731.76
Deduct 480 from 500 and we're left 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 9:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 4731.762
If we subtract 160 from 200, we 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4731.7625
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.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4731.7625
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.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4731.7625
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 4731.7625, and the remainder is 0.0.
