We're dividing 378893 by 75 
The aim is to understand the frequency of 75 in 378893.

Moving on to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 75

On to step 2:
75 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 75

On to step 3:
The number 75 fits into 378 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 375 from 378 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 75

Advancing to step 4:
When dividing 38 by 75, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 38, we get 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 75

Advancing to step 5:
75 can be fit into 389 5 times, resulting in a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
If we take 375 away from 389, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 75

Going ahead to step 6:
When dividing 143 by 75, we get 1 with a remainder of 68.
The next digit of our result is 1. 
Result so far: 5051.0
If we subtract 75 from 143, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
680 divided by 75 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 5051.9
The remainder is 5 after subtracting 675 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 75 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5051.9
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 5051.906
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5051.9066
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 5051.9066, and the remainder is 0.0005.
