We look at the division of 513036 by 52 
The aim is to understand the frequency of 52 in 513036.

On to step 1:
52 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 52

On to step 2:
52 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 52

Going ahead to step 3:
52 goes into 513 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 468 from 513 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 52

On to step 4:
When dividing 450 by 52, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 416 from 450 to get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 52

Advancing to step 5:
52 can be fit into 343 6 times, resulting in a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 986.0
If we take 312 away from 343, we end up with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 52

Let's proceed to step 6:
If we divide 316 by 52, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 9866.0
Subtract 312 from 316 to 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.

Let's proceed to step 7:
If we divide 40 by 52, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9866.0
Subtract 0 from 40 to 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.

Step 8:
The number 52 fits into 400 7 times, leaving a remainder of 36.
The next digit of our result is 7. 
Result so far: 9866.07
If we take 364 away from 400, we end up 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 9:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 9866.076
Subtracting 312 from 360 leaves us 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.

On to step 10:
When dividing 480 by 52, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 9866.0769
Deduct 468 from 480 and we're left 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 11:
52 can be fit into 120 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 9866.07692
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.

Let's proceed to step 12:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 9866.076923
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.

Step 13:
When dividing 40 by 52, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9866.076923
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.

Moving on to step 14:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 9866.07692307
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.

The quotient of the division is 9866.07692307, and the remainder is 3.6e-08.
