1898126 divided by 375 
The aim is to understand the frequency of 375 in 1898126.

Advancing to step 1:
375 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 375

Moving on to step 2:
375 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 375

Going ahead to step 3:
The number 375 fits into 189 0 times, leaving a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 189 after subtracting 0 from 189.
Bring next digit (8) of the dividend behind the 189 and repeat the process: 1898 / 375

Going ahead to step 4:
1898 divided by 375 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 1875 away from 1898, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 375

Moving on to step 5:
375 goes into 231 0 times with a remainder of 231.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 231 after subtracting 0 from 231.
Include the next digit (2) from the dividend after 231, then repeat: 2312 / 375

Step 6:
375 goes into 2312 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
The remainder is 62 after subtracting 2250 from 2312.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 375

On to step 7:
626 divided by 375 is 1 with a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 5061.0
Deduct 375 from 626 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 8:
2510 divided by 375 is 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 5061.6
If we subtract 2250 from 2510, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
2600 divided by 375 is 6 with a remainder of 350.
Put 6 as the next digit of the answer. 
Result so far: 5061.66
The remainder is 350 after subtracting 2250 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 5061.66, with a leftover of 0.35.
