625616 divided by 52 
The aim is to understand the frequency of 52 in 625616.

Step 1:
6 divided by 52 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 52

On to step 2:
62 divided by 52 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 52 from 62, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 52

Advancing to step 3:
52 goes into 105 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 104 from 105 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 52

Let's proceed to step 4:
If we divide 16 by 52, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 120.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 52

Advancing to step 5:
161 divided by 52 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 1203.0
If we subtract 156 from 161, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 52

Advancing to step 6:
When dividing 56 by 52, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 12031.0
If we subtract 52 from 56, 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.

Step 7:
40 divided by 52 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12031.0
Subtract 0 from 40 to get 40.

Let's proceed to step 8:
When dividing 400 by 52, we get 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 12031.07
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
52 goes into 360 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 12031.076
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
52 goes into 480 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 12031.0769
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.

On to step 11:
52 goes into 120 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12031.07692
Subtracting 104 from 120 leaves us 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.

Going ahead to step 12:
52 goes into 160 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 12031.076923
Subtracting 156 from 160 leaves us 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.

Advancing to step 13:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12031.076923
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.

Advancing to step 14:
52 goes into 400 7 times with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 12031.07692307
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.
