Let's divide 379221 by 75
The aim is to understand the frequency of 75 in 379221.

Moving on to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 75

Going ahead to step 2:
The number 75 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 75

Step 3:
The number 75 fits into 379 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
If we take 375 away from 379, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 75

Let's proceed to step 4:
42 divided by 75 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 75

Step 5:
75 can be fit into 422 5 times, resulting in a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Subtracting 375 from 422 leaves us with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 75

Going ahead to step 6:
If we divide 471 by 75, we get 6 and a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 5056.0
Deduct 450 from 471 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
75 can be fit into 210 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 5056.2
Deduct 150 from 210 and we're left 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.

Let's proceed to step 8:
The number 75 fits into 600 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 5056.28
If we subtract 600 from 600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5056.28
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5056.28
Subtracting 0 from 0 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.

The final result is 5056.28 with a remainder of 0.0.
