We look at the division of 30266840 by 375 
The aim is to understand the frequency of 375 in 30266840.

Going ahead to step 1:
375 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 375

Step 2:
375 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 375

Advancing to step 3:
If we divide 302 by 375, we get 0 and a remainder of 302.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 302 after subtracting 0 from 302.
Fetch the next digit (6) from the dividend, attach it to 302 and continue: 3026 / 375

Let's proceed to step 4:
375 goes into 3026 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3000 from 3026 leaves us with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 375

Moving on to step 5:
If we divide 266 by 375, we get 0 and a remainder of 266.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 266 to get 266.
Grab the next digit (8) from the dividend, add it to 266, then carry on: 2668 / 375

Advancing to step 6:
375 can be fit into 2668 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 807.0
If we subtract 2625 from 2668, we get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 375

Going ahead to step 7:
The number 375 fits into 434 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 8071.0
The remainder is 59 after subtracting 375 from 434.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 375

On to step 8:
The number 375 fits into 590 1 times, leaving a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 80711.0
Subtracting 375 from 590 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 9:
When dividing 2150 by 375, we get 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 80711.5
Subtract 1875 from 2150 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 10:
When dividing 2750 by 375, we get 7 with a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 80711.57
The remainder is 125 after subtracting 2625 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 11:
375 can be fit into 1250 3 times, resulting in a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 80711.573
If we subtract 1125 from 1250, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
If we divide 1250 by 375, we get 3 and a remainder of 125.
The next digit of our result is 3. 
Result so far: 80711.5733
Deduct 1125 from 1250 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 80711.5733 and a remainder of 0.00125.
