We look at the division of 66836 by 74 
The aim is to understand the frequency of 74 in 66836.

Step 1:
If we divide 6 by 74, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 74

Going ahead to step 2:
66 divided by 74 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 74

Going ahead to step 3:
74 goes into 668 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 666 away from 668, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 74

Step 4:
When dividing 23 by 74, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 74

Let's proceed to step 5:
When dividing 236 by 74, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 903.0
Subtract 222 from 236 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 6:
140 divided by 74 is 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 903.1
The remainder is 66 after subtracting 74 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
660 divided by 74 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 903.18
If we subtract 592 from 660, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
74 goes into 680 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 903.189
The remainder is 14 after subtracting 666 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 74, we get 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 903.1891
Subtracting 74 from 140 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
If we divide 660 by 74, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 903.18918
Deduct 592 from 660 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
680 divided by 74 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 903.189189
If we take 666 away from 680, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 74, we get 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 903.1891891
Subtracting 74 from 140 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
660 divided by 74 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 903.18918918
If we subtract 592 from 660, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 903.18918918 with a balance of 6.8e-08.
