817940 divided by 52 
The aim is to understand the frequency of 52 in 817940.

Going ahead to step 1:
8 divided by 52 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 52

Moving on to step 2:
52 goes into 81 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 52 from 81 and we're left with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 52

Advancing to step 3:
When dividing 297 by 52, we get 5 with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 260 from 297 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 52

Let's proceed to step 4:
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: 157.0
Subtract 364 from 379 to get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 52

Let's proceed to step 5:
154 divided by 52 is 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 1572.0
Subtract 104 from 154 to get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 52

Step 6:
When dividing 500 by 52, we get 9 with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 15729.0
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 52 fits into 320 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 15729.6
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
52 goes into 80 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 15729.61
Deduct 52 from 80 and we're left 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.

Let's proceed to step 9:
The number 52 fits into 280 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 15729.615
The remainder is 20 after subtracting 260 from 280.
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:
The number 52 fits into 200 3 times, leaving a remainder of 44.
The next digit of our result is 3. 
Result so far: 15729.6153
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
If we divide 440 by 52, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15729.61538
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
52 goes into 240 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 15729.615384
If we subtract 208 from 240, we 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.

Step 13:
52 can be fit into 320 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 15729.6153846
If we subtract 312 from 320, we 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:
52 goes into 80 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 15729.61538461
Deduct 52 from 80 and we're left 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.

The final result is 15729.61538461 with a remainder of 2.8e-08.
