We look at the division of 814345 by 74 
The aim is to understand the frequency of 74 in 814345.

Going ahead to step 1:
When dividing 8 by 74, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 74

Let's proceed to step 2:
When dividing 81 by 74, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 74 from 81 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 74

On to step 3:
When dividing 74 by 74, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 74 from 74 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 74

On to step 4:
74 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 74

Advancing to step 5:
34 divided by 74 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 74

Going ahead to step 6:
The number 74 fits into 345 4 times, leaving a remainder of 49.
The next digit of our result is 4. 
Result so far: 11004.0
Subtract 296 from 345 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
When dividing 490 by 74, we get 6 with a remainder of 46.
The next digit of our result is 6. 
Result so far: 11004.6
If we subtract 444 from 490, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
If we divide 460 by 74, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 11004.66
If we subtract 444 from 460, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 11004.66 with a remainder of 0.016.
