We're dividing 370641 by 75 
The aim is to understand the frequency of 75 in 370641.

Let's proceed to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 75

On to step 2:
When dividing 37 by 75, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 75

On to step 3:
When dividing 370 by 75, we get 4 with a remainder of 70.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 300 from 370 and we're left with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 75

Advancing to step 4:
When dividing 706 by 75, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 675 from 706 to get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 75

Step 5:
If we divide 314 by 75, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 494.0
The remainder is 14 after subtracting 300 from 314.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 75

Let's proceed to step 6:
141 divided by 75 is 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 4941.0
The remainder is 66 after subtracting 75 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
The number 75 fits into 660 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 4941.8
Subtracting 600 from 660 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.

Advancing to step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4941.88
Subtracting 600 from 600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4941.88 with a remaining 0.0.
