We're dividing 21862104 by 375 
The aim is to understand the frequency of 375 in 21862104.

Moving on to step 1:
If we divide 2 by 375, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 375

Let's proceed to step 2:
375 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 375

Going ahead to step 3:
If we divide 218 by 375, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 375

Step 4:
When dividing 2186 by 375, we get 5 with a remainder of 311.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 311 after subtracting 1875 from 2186.
Fetch the next digit (2) from the dividend, attach it to 311 and continue: 3112 / 375

Moving on to step 5:
If we divide 3112 by 375, we get 8 and a remainder of 112.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 3000 from 3112 and we're left with 112.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 375

Step 6:
When dividing 1121 by 375, we get 2 with a remainder of 371.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
Deduct 750 from 1121 and we're left with 371.
Append the next digit (0) from the dividend to 371 and continue with: 3710 / 375

Let's proceed to step 7:
When dividing 3710 by 375, we get 9 with a remainder of 335.
Write down 9 as next digit of the result. 
Result so far: 5829.0
The remainder is 335 after subtracting 3375 from 3710.
Bring next digit (4) of the dividend behind the 335 and repeat the process: 3354 / 375

On to step 8:
375 can be fit into 3354 8 times, resulting in a remainder of 354.
The number 8 becomes the next digit in our result. 
Result so far: 58298.0
The remainder is 354 after subtracting 3000 from 3354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
375 goes into 3540 9 times with a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 58298.9
The remainder is 165 after subtracting 3375 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
When dividing 1650 by 375, we get 4 with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 58298.94
The remainder is 150 after subtracting 1500 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
The number 375 fits into 1500 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 58298.944
Deduct 1500 from 1500 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.

Our division results in 58298.944 with a remaining 0.0.
