Let's divide 385371 by 75
The aim is to understand the frequency of 75 in 385371.

Step 1:
3 divided by 75 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 75

Moving on to step 2:
When dividing 38 by 75, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 75

Step 3:
The number 75 fits into 385 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 375 from 385 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 75

Going ahead to step 4:
103 divided by 75 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 75 from 103 to get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 75

Advancing to step 5:
If we divide 287 by 75, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
Subtracting 225 from 287 leaves us with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 75

On to step 6:
75 goes into 621 8 times with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 5138.0
Subtract 600 from 621 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 75, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 5138.2
Subtracting 150 from 210 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.

Let's proceed to step 8:
75 goes into 600 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 5138.28
The remainder is 0 after subtracting 600 from 600.
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 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5138.28
If we subtract 0 from 0, 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.

Moving on to step 10:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5138.28
If we take 0 away from 0, we end up 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 outcome is 5138.28, with a leftover of 0.0.
