We look at the division of 372850 by 52 
The aim is to understand the frequency of 52 in 372850.

Step 1:
52 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 52

Advancing to step 2:
52 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 52

Let's proceed to step 3:
The number 52 fits into 372 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 364 from 372, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 52

Advancing to step 4:
52 goes into 88 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 52 from 88 leaves us with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 52

Moving on to step 5:
If we divide 365 by 52, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 717.0
The remainder is 1 after subtracting 364 from 365.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 52

Let's proceed to step 6:
52 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7170.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 52, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 7170.1
The remainder is 48 after subtracting 52 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
52 goes into 480 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 7170.19
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
The number 52 fits into 120 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7170.192
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
52 goes into 160 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7170.1923
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7170.1923
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 52, we get 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7170.192307
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 52, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 7170.1923076
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 7170.19230769
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 7170.19230769, with a leftover of 1.2e-08.
