91404665 ÷ 316 
The aim is to understand the frequency of 316 in 91404665.

Let's proceed to step 1:
When dividing 9 by 316, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 316

On to step 2:
316 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 316

Going ahead to step 3:
316 goes into 914 2 times with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 632 from 914 and we're left with 282.
Include the next digit (0) from the dividend after 282, then repeat: 2820 / 316

Step 4:
316 can be fit into 2820 8 times, resulting in a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 2528 from 2820 leaves us with 292.
Bring next digit (4) of the dividend behind the 292 and repeat the process: 2924 / 316

Going ahead to step 5:
When dividing 2924 by 316, we get 9 with a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
Subtract 2844 from 2924 to get 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 316

On to step 6:
316 can be fit into 806 2 times, resulting in a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 2892.0
Subtract 632 from 806 to get 174.
Include the next digit (6) from the dividend after 174, then repeat: 1746 / 316

Advancing to step 7:
If we divide 1746 by 316, we get 5 and a remainder of 166.
The number 5 becomes the next digit in our result. 
Result so far: 28925.0
Subtract 1580 from 1746 to get 166.
Include the next digit (5) from the dividend after 166, then repeat: 1665 / 316

Moving on to step 8:
The number 316 fits into 1665 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 289255.0
If we subtract 1580 from 1665, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
The number 316 fits into 850 2 times, leaving a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 289255.2
If we subtract 632 from 850, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
The number 316 fits into 2180 6 times, leaving a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 289255.26
If we take 1896 away from 2180, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
316 goes into 2840 8 times with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 289255.268
If we subtract 2528 from 2840, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 12:
The number 316 fits into 3120 9 times, leaving a remainder of 276.
Put 9 as the next digit of the answer. 
Result so far: 289255.2689
If we subtract 2844 from 3120, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 13:
The number 316 fits into 2760 8 times, leaving a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 289255.26898
If we subtract 2528 from 2760, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 14:
When dividing 2320 by 316, we get 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 289255.268987
If we subtract 2212 from 2320, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
316 can be fit into 1080 3 times, resulting in a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 289255.2689873
Subtract 948 from 1080 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 16:
316 goes into 1320 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 289255.26898734
Subtract 1264 from 1320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 289255.26898734 and a remainder of 5.6e-08.
