We divide 387719 by 75
The aim is to understand the frequency of 75 in 387719.

Let's proceed to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 75

Advancing to step 2:
If we divide 38 by 75, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 75

Step 3:
The number 75 fits into 387 5 times, leaving a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 375 from 387 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 75

Advancing to step 4:
The number 75 fits into 127 1 times, leaving a remainder of 52.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 75 from 127 leaves us with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 75

Advancing to step 5:
The number 75 fits into 521 6 times, leaving a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
Deduct 450 from 521 and we're left with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 75

Let's proceed to step 6:
When dividing 719 by 75, we get 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 5169.0
The remainder is 44 after subtracting 675 from 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
75 can be fit into 440 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 5169.5
If we subtract 375 from 440, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
When dividing 650 by 75, we get 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 5169.58
Deduct 600 from 650 and we're left 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.

Advancing to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5169.586
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.

Advancing to step 10:
75 goes into 500 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 5169.5866
Deduct 450 from 500 and we're left 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.

The final result is 5169.5866 with a remainder of 0.0005.
