371858 divided by 80 
Our goal is to divide 371858 by 80.

Going ahead to step 1:
80 can be fit into 3 0 times, resulting in 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.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 80

Going ahead to step 2:
If we divide 37 by 80, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 80

Moving on to step 3:
If we divide 371 by 80, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 320 from 371, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 80

Moving on to step 4:
The number 80 fits into 518 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 480 away from 518, we end up with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 80

Moving on to step 5:
If we divide 385 by 80, we get 4 and a remainder of 65.
The next digit of our result is 4. 
Result so far: 464.0
If we subtract 320 from 385, we get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 80

On to step 6:
80 can be fit into 658 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4648.0
If we take 640 away from 658, we end up 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.

Moving on to step 7:
180 divided by 80 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 4648.2
The remainder is 20 after subtracting 160 from 180.
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:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 4648.22
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.

The final result is 4648.22 with a remainder of 0.04.
