We're dividing 78556686 by 375 
The aim is to understand the frequency of 375 in 78556686.

Advancing to step 1:
375 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 375

On to step 2:
375 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 375

Going ahead to step 3:
375 goes into 785 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 750 from 785, we get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 375

Step 4:
375 can be fit into 355 0 times, resulting in a remainder of 355.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 355, we get 355.
Fetch the next digit (6) from the dividend, attach it to 355 and continue: 3556 / 375

Let's proceed to step 5:
375 goes into 3556 9 times with a remainder of 181.
The next digit of our result is 9. 
Result so far: 209.0
If we take 3375 away from 3556, we end up with 181.
Take the next digit (6) from the dividend and append it to 181, then repeat: 1816 / 375

Going ahead to step 6:
1816 divided by 375 is 4 with a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 2094.0
If we subtract 1500 from 1816, we get 316.
Include the next digit (8) from the dividend after 316, then repeat: 3168 / 375

Moving on to step 7:
375 goes into 3168 8 times with a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 20948.0
If we subtract 3000 from 3168, we get 168.
Include the next digit (6) from the dividend after 168, then repeat: 1686 / 375

Step 8:
When dividing 1686 by 375, we get 4 with a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 209484.0
Deduct 1500 from 1686 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 9:
If we divide 1860 by 375, we get 4 and a remainder of 360.
The next digit of our result is 4. 
Result so far: 209484.4
If we subtract 1500 from 1860, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
375 goes into 3600 9 times with a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 209484.49
Deduct 3375 from 3600 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
If we divide 2250 by 375, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 209484.496
Subtracting 2250 from 2250 leaves us 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.

Step 12:
375 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 209484.496
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 13:
375 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 209484.496
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.

The final outcome is 209484.496, with a leftover of 0.0.
