We look at the division of 317809 by 79 
We're looking to find how many times 79 goes into 317809.

Moving on to step 1:
When dividing 3 by 79, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 79

On to step 2:
When dividing 31 by 79, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 79

Advancing to step 3:
79 can be fit into 317 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 316 from 317.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 79

Going ahead to step 4:
79 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 79

Advancing to step 5:
The number 79 fits into 180 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Deduct 158 from 180 and we're left with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 79

Step 6:
229 divided by 79 is 2 with a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 4022.0
Subtracting 158 from 229 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
710 divided by 79 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 4022.8
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
79 goes into 780 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 4022.89
Subtract 711 from 780 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
690 divided by 79 is 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 4022.898
If we subtract 632 from 690, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
79 can be fit into 580 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 4022.8987
The remainder is 27 after subtracting 553 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
When dividing 270 by 79, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 4022.89873
Subtract 237 from 270 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
If we divide 330 by 79, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4022.898734
Subtracting 316 from 330 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
140 divided by 79 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 4022.8987341
Subtract 79 from 140 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
If we divide 610 by 79, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 4022.89873417
If we take 553 away from 610, we end up 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.

Our division results in 4022.89873417 with a remaining 5.7e-08.
