We divide 315319 by 79
We want to divide 315319 by 79.

On to step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 79

Going ahead to step 2:
79 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 79

Moving on to step 3:
If we divide 315 by 79, we get 3 and a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 237 from 315, we get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 79

Advancing to step 4:
79 can be fit into 783 9 times, resulting in a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 711 from 783, we get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 79

Moving on to step 5:
The number 79 fits into 721 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 399.0
Subtract 711 from 721 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 79

Let's proceed to step 6:
79 goes into 109 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 3991.0
Subtracting 79 from 109 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 79 fits into 300 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 3991.3
Subtract 237 from 300 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
If we divide 630 by 79, we get 7 and a remainder of 77.
The next digit of our result is 7. 
Result so far: 3991.37
Deduct 553 from 630 and we're left 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.

Step 9:
770 divided by 79 is 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 3991.379
If we subtract 711 from 770, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
590 divided by 79 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3991.3797
Deduct 553 from 590 and we're left 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 11:
79 goes into 370 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 3991.37974
Subtracting 316 from 370 leaves us 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.

Step 12:
When dividing 540 by 79, we get 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 3991.379746
Subtract 474 from 540 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
The number 79 fits into 660 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 3991.3797468
If we subtract 632 from 660, we 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 14:
79 goes into 280 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3991.37974683
Deduct 237 from 280 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 3991.37974683 with a balance of 4.3e-08.
