207531 divided by 52 
The aim is to understand the frequency of 52 in 207531.

On to step 1:
2 divided by 52 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 52

On to step 2:
52 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 52

Going ahead to step 3:
The number 52 fits into 207 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 51 after subtracting 156 from 207.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 52

Let's proceed to step 4:
52 can be fit into 515 9 times, resulting in a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 468 from 515, we get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 52

Advancing to step 5:
If we divide 473 by 52, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 399.0
Subtract 468 from 473 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 52

Advancing to step 6:
52 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 3990.0
Subtract 0 from 51 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
The number 52 fits into 510 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 3990.9
If we subtract 468 from 510, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
52 goes into 420 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3990.98
The remainder is 4 after subtracting 416 from 420.
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 9:
40 divided by 52 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3990.98
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 52 fits into 400 7 times, leaving a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 3990.9807
If we subtract 364 from 400, we get 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 11:
360 divided by 52 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3990.98076
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.

Going ahead to step 12:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 3990.980769
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.

Going ahead to step 13:
If we divide 120 by 52, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 3990.9807692
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
If we divide 160 by 52, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3990.98076923
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.

The final result is 3990.98076923 with a remainder of 4e-09.
