We look at the division of 75108669 by 375 
The aim is to understand the frequency of 375 in 75108669.

Moving on to step 1:
If we divide 7 by 375, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 375

On to step 2:
375 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 375

Advancing to step 3:
When dividing 751 by 375, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 750 from 751 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 375

On to step 4:
When dividing 10 by 375, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 375

Going ahead to step 5:
375 goes into 108 0 times with a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Deduct 0 from 108 and we're left with 108.
Fetch the next digit (6) from the dividend, attach it to 108 and continue: 1086 / 375

Advancing to step 6:
375 can be fit into 1086 2 times, resulting in a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 2002.0
If we take 750 away from 1086, we end up with 336.
Take the next digit (6) from the dividend and append it to 336, then repeat: 3366 / 375

Moving on to step 7:
When dividing 3366 by 375, we get 8 with a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 20028.0
If we take 3000 away from 3366, we end up with 366.
Take the next digit (9) from the dividend and append it to 366, then repeat: 3669 / 375

Step 8:
If we divide 3669 by 375, we get 9 and a remainder of 294.
The number 9 becomes the next digit in our result. 
Result so far: 200289.0
The remainder is 294 after subtracting 3375 from 3669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
When dividing 2940 by 375, we get 7 with a remainder of 315.
The number 7 becomes the next digit in our result. 
Result so far: 200289.7
The remainder is 315 after subtracting 2625 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 10:
When dividing 3150 by 375, we get 8 with a remainder of 150.
Use 8 as the next digit of our solution. 
Result so far: 200289.78
If we take 3000 away from 3150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
When dividing 1500 by 375, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 200289.784
Subtract 1500 from 1500 to 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.

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: 200289.784
Deduct 0 from 0 and we're left 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.

On to step 13:
If we divide 0 by 375, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 200289.784
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 200289.784 and a remainder of 0.0.
