We look at the division of 308425 by 74 
The aim is to understand the frequency of 74 in 308425.

On to step 1:
74 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 74

Step 2:
74 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 74

On to step 3:
308 divided by 74 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 296 from 308 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 74

Advancing to step 4:
74 goes into 124 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we subtract 74 from 124, we get 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 74

Step 5:
The number 74 fits into 502 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 416.0
If we take 444 away from 502, we end up with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 74

Going ahead to step 6:
74 goes into 585 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 4167.0
The remainder is 67 after subtracting 518 from 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
If we divide 670 by 74, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 4167.9
If we subtract 666 from 670, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 74 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4167.9
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
74 can be fit into 400 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4167.905
Subtracting 370 from 400 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 74 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4167.9054
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
74 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4167.9054
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 74 fits into 400 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 4167.905405
Subtract 370 from 400 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
300 divided by 74 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4167.9054054
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 74, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4167.9054054
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 4167.9054054 and a remainder of 4e-08.
