We look at the division of 32134375 by 375 
The aim is to understand the frequency of 375 in 32134375.

On to step 1:
When dividing 3 by 375, we get 0 with 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.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 375

Let's proceed to step 2:
The number 375 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 375

Advancing to step 3:
If we divide 321 by 375, we get 0 and a remainder of 321.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 321 after subtracting 0 from 321.
Take the next digit (3) from the dividend and append it to 321, then repeat: 3213 / 375

Going ahead to step 4:
375 goes into 3213 8 times with a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 3000 away from 3213, we end up with 213.
Grab the next digit (4) from the dividend, add it to 213, then carry on: 2134 / 375

Step 5:
The number 375 fits into 2134 5 times, leaving a remainder of 259.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 1875 from 2134, we get 259.
Include the next digit (3) from the dividend after 259, then repeat: 2593 / 375

Moving on to step 6:
375 can be fit into 2593 6 times, resulting in a remainder of 343.
Write down 6 as next digit of the result. 
Result so far: 856.0
Subtract 2250 from 2593 to get 343.
Bring next digit (7) of the dividend behind the 343 and repeat the process: 3437 / 375

On to step 7:
375 can be fit into 3437 9 times, resulting in a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 8569.0
Subtract 3375 from 3437 to get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 375

On to step 8:
When dividing 625 by 375, we get 1 with a remainder of 250.
Write down 1 as next digit of the result. 
Result so far: 85691.0
The remainder is 250 after subtracting 375 from 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 9:
The number 375 fits into 2500 6 times, leaving a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 85691.6
Deduct 2250 from 2500 and we're left 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.

On to step 10:
The number 375 fits into 2500 6 times, leaving a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 85691.66
If we subtract 2250 from 2500, we 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.

After the division, we end up with 85691.66 and a remainder of 0.25.
