We look at the division of 45601033 by 375 
The aim is to understand the frequency of 375 in 45601033.

Moving on to step 1:
When dividing 4 by 375, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 375

Let's proceed to step 2:
375 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 375

Moving on to step 3:
The number 375 fits into 456 1 times, leaving a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 81 after subtracting 375 from 456.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 375

Moving on to step 4:
375 goes into 810 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 750 from 810 and we're left with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 375

Going ahead to step 5:
If we divide 601 by 375, we get 1 and a remainder of 226.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 226 after subtracting 375 from 601.
Include the next digit (0) from the dividend after 226, then repeat: 2260 / 375

Moving on to step 6:
375 can be fit into 2260 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1216.0
Deduct 2250 from 2260 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 375

Moving on to step 7:
When dividing 103 by 375, we get 0 with a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 12160.0
Subtracting 0 from 103 leaves us with 103.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 375

Advancing to step 8:
When dividing 1033 by 375, we get 2 with a remainder of 283.
Write down 2 as next digit of the result. 
Result so far: 121602.0
Deduct 750 from 1033 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 9:
If we divide 2830 by 375, we get 7 and a remainder of 205.
Record the quotient 7 as the next digit in the result. 
Result so far: 121602.7
The remainder is 205 after subtracting 2625 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 10:
375 goes into 2050 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 121602.75
Deduct 1875 from 2050 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 11:
If we divide 1750 by 375, we get 4 and a remainder of 250.
Put 4 as the next digit of the answer. 
Result so far: 121602.754
Deduct 1500 from 1750 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
375 goes into 2500 6 times with a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 121602.7546
If we subtract 2250 from 2500, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
If we divide 2500 by 375, we get 6 and a remainder of 250.
Use 6 as the next digit of our solution. 
Result so far: 121602.75466
If we take 2250 away from 2500, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 121602.75466, with a leftover of 0.00025.
