We look at the division of 80291517 by 316 
The aim is to understand the frequency of 316 in 80291517.

Moving on to step 1:
If we divide 8 by 316, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 316

On to step 2:
80 divided by 316 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 316

Advancing to step 3:
When dividing 802 by 316, we get 2 with a remainder of 170.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 632 from 802 and we're left with 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 316

On to step 4:
The number 316 fits into 1709 5 times, leaving a remainder of 129.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 1580 from 1709, we get 129.
Fetch the next digit (1) from the dividend, attach it to 129 and continue: 1291 / 316

Going ahead to step 5:
1291 divided by 316 is 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Deduct 1264 from 1291 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 316

Moving on to step 6:
316 goes into 275 0 times with a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 2540.0
If we take 0 away from 275, we end up with 275.
Take the next digit (1) from the dividend and append it to 275, then repeat: 2751 / 316

Going ahead to step 7:
If we divide 2751 by 316, we get 8 and a remainder of 223.
The number 8 becomes the next digit in our result. 
Result so far: 25408.0
The remainder is 223 after subtracting 2528 from 2751.
Fetch the next digit (7) from the dividend, attach it to 223 and continue: 2237 / 316

Step 8:
When dividing 2237 by 316, we get 7 with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 254087.0
The remainder is 25 after subtracting 2212 from 2237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
If we divide 250 by 316, we get 0 and a remainder of 250.
The next digit of our result is 0. 
Result so far: 254087.0
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
The number 316 fits into 2500 7 times, leaving a remainder of 288.
The number 7 becomes the next digit in our result. 
Result so far: 254087.07
Subtract 2212 from 2500 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 11:
If we divide 2880 by 316, we get 9 and a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 254087.079
The remainder is 36 after subtracting 2844 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 316, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 254087.0791
Deduct 316 from 360 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
If we divide 440 by 316, we get 1 and a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 254087.07911
Deduct 316 from 440 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 254087.07911 with a remainder of 0.000124.
