625839 divided by 52 
The aim is to understand the frequency of 52 in 625839.

On to step 1:
When dividing 6 by 52, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 52

Moving on to step 2:
52 goes into 62 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 52 from 62, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 52

Moving on to step 3:
The number 52 fits into 105 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 1 after subtracting 104 from 105.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 52

Step 4:
If we divide 18 by 52, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 52

On to step 5:
When dividing 183 by 52, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 1203.0
The remainder is 27 after subtracting 156 from 183.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 52

On to step 6:
When dividing 279 by 52, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 12035.0
Deduct 260 from 279 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 52, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 12035.3
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
The number 52 fits into 340 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 12035.36
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
The number 52 fits into 280 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 12035.365
If we subtract 260 from 280, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
When dividing 200 by 52, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 12035.3653
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
If we divide 440 by 52, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12035.36538
Subtracting 416 from 440 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
If we divide 240 by 52, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 12035.365384
Subtract 208 from 240 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
320 divided by 52 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 12035.3653846
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
When dividing 80 by 52, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 12035.36538461
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 12035.36538461 and a remainder of 2.8e-08.
