We look at the division of 261374 by 52 
The aim is to understand the frequency of 52 in 261374.

On to step 1:
If we divide 2 by 52, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 52

On to step 2:
52 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 52

Going ahead to step 3:
If we divide 261 by 52, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 260 from 261 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 52

Advancing to step 4:
The number 52 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 13, we end up with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 52

Step 5:
52 goes into 137 2 times with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
Deduct 104 from 137 and we're left with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 52

Let's proceed to step 6:
The number 52 fits into 334 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 5026.0
If we take 312 away from 334, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
220 divided by 52 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 5026.4
Subtracting 208 from 220 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 8:
When dividing 120 by 52, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 5026.42
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.

Going ahead to step 9:
When dividing 160 by 52, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 5026.423
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.

Step 10:
52 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5026.423
The remainder is 40 after subtracting 0 from 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 11:
The number 52 fits into 400 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 5026.42307
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 12:
360 divided by 52 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 5026.423076
Deduct 312 from 360 and we're left 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.

Going ahead to step 13:
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: 5026.4230769
If we subtract 468 from 480, we 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 14:
52 can be fit into 120 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 5026.42307692
Subtract 104 from 120 to 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.

Our division results in 5026.42307692 with a remaining 1.6e-08.
