399095 divided by 74 
The aim is to understand the frequency of 74 in 399095.

On to step 1:
The number 74 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 74

Going ahead to step 2:
When dividing 39 by 74, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 74

On to step 3:
74 goes into 399 5 times with a remainder of 29.
The next digit of our result is 5. 
Result so far: 5.0
If we take 370 away from 399, we end up with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 74

Step 4:
74 can be fit into 290 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 222 from 290 to get 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 74

Step 5:
689 divided by 74 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 539.0
If we take 666 away from 689, we end up with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 74

Step 6:
The number 74 fits into 235 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 5393.0
Subtracting 222 from 235 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
The number 74 fits into 130 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 5393.1
Subtract 74 from 130 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.

Advancing to step 8:
74 can be fit into 560 7 times, resulting in a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 5393.17
Subtracting 518 from 560 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
74 can be fit into 420 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 5393.175
If we subtract 370 from 420, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 74 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 5393.1756
If we take 444 away from 500, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
When dividing 560 by 74, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 5393.17567
If we subtract 518 from 560, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
74 goes into 420 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5393.175675
Subtracting 370 from 420 leaves us 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.

Moving on to step 13:
500 divided by 74 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 5393.1756756
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
560 divided by 74 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 5393.17567567
Subtracting 518 from 560 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 5393.17567567 with a remainder of 4.2e-08.
