Let's divide 313398 by 80
We want to divide 313398 by 80.

Moving on to step 1:
80 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 80

Going ahead to step 2:
The number 80 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 80

Moving on to step 3:
When dividing 313 by 80, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 240 from 313, we get 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 80

Let's proceed to step 4:
The number 80 fits into 733 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 13 after subtracting 720 from 733.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 80

On to step 5:
The number 80 fits into 139 1 times, leaving a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 391.0
If we subtract 80 from 139, we get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 80

Step 6:
When dividing 598 by 80, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 3917.0
Subtracting 560 from 598 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
80 goes into 380 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 3917.4
Deduct 320 from 380 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 3917.47
Subtract 560 from 600 to 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.

Going ahead to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3917.475
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.

Moving on to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3917.475
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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3917.475
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.

Our division results in 3917.475 with a remaining 0.0.
