We're dividing 3506071 by 74 
The aim is to understand the frequency of 74 in 3506071.

Step 1:
74 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 74

Moving on to step 2:
74 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 74

Moving on to step 3:
The number 74 fits into 350 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 54 after subtracting 296 from 350.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 74

Moving on to step 4:
546 divided by 74 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 518 away from 546, we end up with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 74

Advancing to step 5:
If we divide 280 by 74, we get 3 and a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
Subtract 222 from 280 to get 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 74

On to step 6:
74 goes into 587 7 times with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 4737.0
The remainder is 69 after subtracting 518 from 587.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 74

On to step 7:
691 divided by 74 is 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 47379.0
Subtracting 666 from 691 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
74 goes into 250 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 47379.3
Deduct 222 from 250 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
74 can be fit into 280 3 times, resulting in a remainder of 58.
The next digit of our result is 3. 
Result so far: 47379.33
The remainder is 58 after subtracting 222 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 47379.33 with a remainder of 0.058.
