We look at the division of 870485 by 74 
The aim is to understand the frequency of 74 in 870485.

On to step 1:
When dividing 8 by 74, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 74

On to step 2:
If we divide 87 by 74, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 13 after subtracting 74 from 87.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 74

Advancing to step 3:
When dividing 130 by 74, we get 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 74 from 130 and we're left with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 74

Let's proceed to step 4:
564 divided by 74 is 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 518 from 564, we get 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 74

On to step 5:
The number 74 fits into 468 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1176.0
If we subtract 444 from 468, we get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 74

On to step 6:
245 divided by 74 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 11763.0
If we subtract 222 from 245, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
74 can be fit into 230 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 11763.3
Subtract 222 from 230 to 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.

Let's proceed to step 8:
74 goes into 80 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 11763.31
If we subtract 74 from 80, we get 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 9:
60 divided by 74 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 11763.31
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.

Going ahead to step 10:
If we divide 600 by 74, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 11763.3108
Subtracting 592 from 600 leaves us 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.

Let's proceed to step 11:
80 divided by 74 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11763.31081
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
74 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 11763.31081
The remainder is 60 after subtracting 0 from 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 13:
74 goes into 600 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11763.3108108
Subtract 592 from 600 to 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.

Let's proceed to step 14:
If we divide 80 by 74, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11763.31081081
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 11763.31081081 with a balance of 6e-09.
