Let's divide 318617 by 80
Let's see how many times 80 fits into 318617.

Advancing to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 80

On to step 2:
80 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 80

On to step 3:
When dividing 318 by 80, we get 3 with a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 240 away from 318, we end up with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 80

Going ahead to step 4:
The number 80 fits into 786 9 times, leaving a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 720 away from 786, we end up with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 80

On to step 5:
661 divided by 80 is 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we take 640 away from 661, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 80

Going ahead to step 6:
80 goes into 217 2 times with a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 3982.0
Deduct 160 from 217 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
80 goes into 570 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3982.7
The remainder is 10 after subtracting 560 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 80 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 3982.71
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 3982.712
Deduct 160 from 200 and we're left 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.

Moving on to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3982.7125
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3982.7125
Subtract 0 from 0 to 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.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3982.7125
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.

After the division, we end up with 3982.7125 and a remainder of 0.0.
