We're dividing 331640 by 79 
We're looking to find how many times 79 goes into 331640.

On to step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 79

Moving on to step 2:
When dividing 33 by 79, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 79

Step 3:
When dividing 331 by 79, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 316 from 331 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 79

On to step 4:
The number 79 fits into 156 1 times, leaving a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 79 from 156 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 79

Let's proceed to step 5:
774 divided by 79 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 419.0
The remainder is 63 after subtracting 711 from 774.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 79

Moving on to step 6:
79 goes into 630 7 times with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 4197.0
Subtracting 553 from 630 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
The number 79 fits into 770 9 times, leaving a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 4197.9
Subtracting 711 from 770 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 8:
590 divided by 79 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 4197.97
Subtracting 553 from 590 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
If we divide 370 by 79, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 4197.974
If we take 316 away from 370, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
The number 79 fits into 540 6 times, leaving a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 4197.9746
Deduct 474 from 540 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
79 goes into 660 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4197.97468
Subtract 632 from 660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
When dividing 280 by 79, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 4197.974683
If we subtract 237 from 280, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
430 divided by 79 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4197.9746835
If we take 395 away from 430, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
79 goes into 350 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 4197.97468354
The remainder is 34 after subtracting 316 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 4197.97468354 and a remainder of 3.4e-08.
