We're dividing 145865 by 74 
The aim is to understand the frequency of 74 in 145865.

Step 1:
74 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 74

Advancing to step 2:
When dividing 14 by 74, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 74

Advancing to step 3:
145 divided by 74 is 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 74 from 145 leaves us with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 74

On to step 4:
When dividing 718 by 74, we get 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 666 from 718 and we're left with 52.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 74

Let's proceed to step 5:
If we divide 526 by 74, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Subtract 518 from 526 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 74

Let's proceed to step 6:
74 goes into 85 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1971.0
If we take 74 away from 85, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 74 fits into 110 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1971.1
The remainder is 36 after subtracting 74 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 74 fits into 360 4 times, leaving a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 1971.14
The remainder is 64 after subtracting 296 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
If we divide 640 by 74, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1971.148
Subtracting 592 from 640 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
The number 74 fits into 480 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 1971.1486
If we take 444 away from 480, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
When dividing 360 by 74, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1971.14864
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
74 can be fit into 640 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1971.148648
If we take 592 away from 640, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
74 can be fit into 480 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1971.1486486
Subtract 444 from 480 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 74, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 1971.14864864
Subtract 296 from 360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 1971.14864864 with a remainder of 6.4e-08.
