784515 ÷ 74 
The aim is to understand the frequency of 74 in 784515.

Let's proceed to step 1:
If we divide 7 by 74, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 74

Going ahead to step 2:
74 can be fit into 78 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 74 from 78 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 74

Let's proceed to step 3:
The number 74 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 74

Moving on to step 4:
The number 74 fits into 445 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 444 from 445, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 74

Moving on to step 5:
74 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 1060.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 74

Let's proceed to step 6:
74 can be fit into 115 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 10601.0
If we take 74 away from 115, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
When dividing 410 by 74, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 10601.5
Deduct 370 from 410 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
74 can be fit into 400 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 10601.55
Subtract 370 from 400 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 10601.55 with a remainder of 0.03.
