69719287 divided by 375 
The aim is to understand the frequency of 375 in 69719287.

Step 1:
6 divided by 375 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 375

Step 2:
If we divide 69 by 375, we get 0 and a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 375

Moving on to step 3:
697 divided by 375 is 1 with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 375 from 697 and we're left with 322.
Append the next digit (1) from the dividend to 322 and continue with: 3221 / 375

On to step 4:
3221 divided by 375 is 8 with a remainder of 221.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3000 from 3221, we get 221.
Bring next digit (9) of the dividend behind the 221 and repeat the process: 2219 / 375

Advancing to step 5:
If we divide 2219 by 375, we get 5 and a remainder of 344.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtract 1875 from 2219 to get 344.
Append the next digit (2) from the dividend to 344 and continue with: 3442 / 375

Advancing to step 6:
If we divide 3442 by 375, we get 9 and a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 1859.0
If we take 3375 away from 3442, we end up with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 375

Moving on to step 7:
If we divide 678 by 375, we get 1 and a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 18591.0
The remainder is 303 after subtracting 375 from 678.
Take the next digit (7) from the dividend and append it to 303, then repeat: 3037 / 375

Advancing to step 8:
The number 375 fits into 3037 8 times, leaving a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 185918.0
Subtracting 3000 from 3037 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
370 divided by 375 is 0 with a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 185918.0
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
When dividing 3700 by 375, we get 9 with a remainder of 325.
Use 9 as the next digit of our solution. 
Result so far: 185918.09
Subtract 3375 from 3700 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 11:
3250 divided by 375 is 8 with a remainder of 250.
Write down 8 as next digit of the result. 
Result so far: 185918.098
If we take 3000 away from 3250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
375 can be fit into 2500 6 times, resulting in a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 185918.0986
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
375 can be fit into 2500 6 times, resulting in a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 185918.09866
Subtract 2250 from 2500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 185918.09866, with a leftover of 0.00025.
