We divide 539393 by 52
The aim is to understand the frequency of 52 in 539393.

On to step 1:
52 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 52

On to step 2:
52 goes into 53 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 53, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 52

Going ahead to step 3:
When dividing 19 by 52, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 52

Step 4:
If we divide 193 by 52, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 156 from 193 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 52

On to step 5:
If we divide 379 by 52, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 1037.0
The remainder is 15 after subtracting 364 from 379.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 52

Moving on to step 6:
The number 52 fits into 153 2 times, leaving a remainder of 49.
The next digit of our result is 2. 
Result so far: 10372.0
Deduct 104 from 153 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
52 goes into 490 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 10372.9
Deduct 468 from 490 and we're left 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.

Advancing to step 8:
52 can be fit into 220 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 10372.94
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 9:
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: 10372.942
If we subtract 104 from 120, we 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.

Step 10:
160 divided by 52 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 10372.9423
Subtract 156 from 160 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.

Going ahead to step 11:
40 divided by 52 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10372.9423
Deduct 0 from 40 and we're left 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.

On to step 12:
52 can be fit into 400 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 10372.942307
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.

On to step 13:
When dividing 360 by 52, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 10372.9423076
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.

Moving on to step 14:
480 divided by 52 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 10372.94230769
If we take 468 away from 480, we end up 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.

Our division results in 10372.94230769 with a remaining 1.2e-08.
