We look at the division of 645767 by 74 
The aim is to understand the frequency of 74 in 645767.

On to step 1:
74 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 74

Step 2:
If we divide 64 by 74, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 74

Advancing to step 3:
When dividing 645 by 74, we get 8 with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 592 from 645 and we're left with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 74

Going ahead to step 4:
74 can be fit into 537 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 518 from 537 to get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 74

Let's proceed to step 5:
74 goes into 196 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Subtract 148 from 196 to get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 74

On to step 6:
487 divided by 74 is 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 8726.0
If we subtract 444 from 487, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
430 divided by 74 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 8726.5
If we take 370 away from 430, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 74 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8726.58
Deduct 592 from 600 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 74 fits into 80 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 8726.581
Deduct 74 from 80 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
74 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 8726.581
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 74 fits into 600 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 8726.58108
If we subtract 592 from 600, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 74, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 8726.581081
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
74 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 8726.581081
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
When dividing 600 by 74, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8726.58108108
If we subtract 592 from 600, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 8726.58108108 with a balance of 8e-09.
