We look at the division of 72313490 by 316 
The aim is to understand the frequency of 316 in 72313490.

Moving on to step 1:
316 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 316

Step 2:
72 divided by 316 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 316

Going ahead to step 3:
The number 316 fits into 723 2 times, leaving a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 632 from 723, we get 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 316

On to step 4:
316 can be fit into 911 2 times, resulting in a remainder of 279.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 632 from 911, we get 279.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 316

Going ahead to step 5:
316 can be fit into 2793 8 times, resulting in a remainder of 265.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
If we take 2528 away from 2793, we end up with 265.
Take the next digit (4) from the dividend and append it to 265, then repeat: 2654 / 316

On to step 6:
The number 316 fits into 2654 8 times, leaving a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 2288.0
If we take 2528 away from 2654, we end up with 126.
Append the next digit (9) from the dividend to 126 and continue with: 1269 / 316

Step 7:
316 can be fit into 1269 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 22884.0
The remainder is 5 after subtracting 1264 from 1269.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 316

Advancing to step 8:
316 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 228840.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 316, we get 1 and a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 228840.1
The remainder is 184 after subtracting 316 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
The number 316 fits into 1840 5 times, leaving a remainder of 260.
Put 5 as the next digit of the answer. 
Result so far: 228840.15
Subtracting 1580 from 1840 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 11:
316 can be fit into 2600 8 times, resulting in a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 228840.158
Subtract 2528 from 2600 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
316 goes into 720 2 times with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 228840.1582
If we take 632 away from 720, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
880 divided by 316 is 2 with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 228840.15822
Subtracting 632 from 880 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 228840.15822 with a remainder of 0.000248.
