We're dividing 79859171 by 316 
We want to figure out the number of times 79859171 can be divided by 316.

On to step 1:
316 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 316

Going ahead to step 2:
If we divide 79 by 316, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 316

Advancing to step 3:
If we divide 798 by 316, we get 2 and a remainder of 166.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 166 after subtracting 632 from 798.
Include the next digit (5) from the dividend after 166, then repeat: 1665 / 316

Let's proceed to step 4:
316 goes into 1665 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1580 from 1665 and we're left with 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 316

Moving on to step 5:
If we divide 859 by 316, we get 2 and a remainder of 227.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
The remainder is 227 after subtracting 632 from 859.
Bring next digit (1) of the dividend behind the 227 and repeat the process: 2271 / 316

Advancing to step 6:
316 goes into 2271 7 times with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 2527.0
Deduct 2212 from 2271 and we're left with 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 316

Going ahead to step 7:
When dividing 597 by 316, we get 1 with a remainder of 281.
The next digit of our result is 1. 
Result so far: 25271.0
If we subtract 316 from 597, we get 281.
Bring next digit (1) of the dividend behind the 281 and repeat the process: 2811 / 316

Step 8:
316 goes into 2811 8 times with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 252718.0
Subtracting 2528 from 2811 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 9:
The number 316 fits into 2830 8 times, leaving a remainder of 302.
The next digit of our result is 8. 
Result so far: 252718.8
Subtracting 2528 from 2830 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 10:
3020 divided by 316 is 9 with a remainder of 176.
The number 9 becomes the next digit in our result. 
Result so far: 252718.89
If we subtract 2844 from 3020, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
If we divide 1760 by 316, we get 5 and a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 252718.895
Subtract 1580 from 1760 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
If we divide 1800 by 316, we get 5 and a remainder of 220.
The next digit of our result is 5. 
Result so far: 252718.8955
Deduct 1580 from 1800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 252718.8955 and a remainder of 0.0022.
