77834500 ÷ 375 
The aim is to understand the frequency of 375 in 77834500.

On to step 1:
When dividing 7 by 375, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 375

Advancing to step 2:
375 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 375

Going ahead to step 3:
778 divided by 375 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 750 from 778 and we're left with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 375

Let's proceed to step 4:
375 goes into 283 0 times with a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 283 and we're left with 283.
Bring next digit (4) of the dividend behind the 283 and repeat the process: 2834 / 375

Going ahead to step 5:
375 can be fit into 2834 7 times, resulting in a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
If we subtract 2625 from 2834, we get 209.
Include the next digit (5) from the dividend after 209, then repeat: 2095 / 375

On to step 6:
375 can be fit into 2095 5 times, resulting in a remainder of 220.
The next digit of our result is 5. 
Result so far: 2075.0
If we subtract 1875 from 2095, we get 220.
Append the next digit (0) from the dividend to 220 and continue with: 2200 / 375

On to step 7:
375 can be fit into 2200 5 times, resulting in a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 20755.0
The remainder is 325 after subtracting 1875 from 2200.
Include the next digit (0) from the dividend after 325, then repeat: 3250 / 375

Advancing to step 8:
375 goes into 3250 8 times with a remainder of 250.
Put 8 as the next digit of the answer. 
Result so far: 207558.0
Deduct 3000 from 3250 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.

Moving on to step 9:
2500 divided by 375 is 6 with a remainder of 250.
Use 6 as the next digit of our solution. 
Result so far: 207558.6
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.

Let's proceed to step 10:
If we divide 2500 by 375, we get 6 and a remainder of 250.
Record the quotient 6 as the next digit in the result. 
Result so far: 207558.66
If we take 2250 away from 2500, 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.

The final result is 207558.66 with a remainder of 0.25.
