We look at the division of 420874 by 52 
The aim is to understand the frequency of 52 in 420874.

Advancing to step 1:
When dividing 4 by 52, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 52

Let's proceed to step 2:
If we divide 42 by 52, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 52

Step 3:
52 goes into 420 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 4 after subtracting 416 from 420.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 52

Going ahead to step 4:
If we divide 48 by 52, we get 0 and a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 48 leaves us with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 52

Moving on to step 5:
52 can be fit into 487 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
The remainder is 19 after subtracting 468 from 487.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 52

Advancing to step 6:
52 goes into 194 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 8093.0
The remainder is 38 after subtracting 156 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
52 goes into 380 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 8093.7
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 8093.73
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 52, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8093.73
Deduct 0 from 40 and we're left 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.

Advancing to step 10:
52 can be fit into 400 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 8093.7307
Deduct 364 from 400 and we're left 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.

On to step 11:
360 divided by 52 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 8093.73076
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.

Step 12:
52 goes into 480 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 8093.730769
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
The number 52 fits into 120 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 8093.7307692
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 52, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 8093.73076923
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 8093.73076923 and a remainder of 4e-09.
