Let's divide 400343 by 52
The aim is to understand the frequency of 52 in 400343.

Advancing to step 1:
52 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 52

On to step 2:
52 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 52

On to step 3:
400 divided by 52 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 364 from 400 to get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 52

Moving on to step 4:
If we divide 363 by 52, we get 6 and a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 312 from 363 leaves us with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 52

Moving on to step 5:
514 divided by 52 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 769.0
If we subtract 468 from 514, we get 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 52

Step 6:
463 divided by 52 is 8 with a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 7698.0
If we subtract 416 from 463, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
The number 52 fits into 470 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7698.9
Subtract 468 from 470 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
52 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7698.9
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
52 goes into 200 3 times with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 7698.903
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
52 goes into 440 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 7698.9038
If we take 416 away from 440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 52 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 7698.90384
Subtract 208 from 240 to 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.

Let's proceed to step 12:
The number 52 fits into 320 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7698.903846
Subtracting 312 from 320 leaves us 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.

Moving on to step 13:
If we divide 80 by 52, we get 1 and a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7698.9038461
The remainder is 28 after subtracting 52 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
52 can be fit into 280 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7698.90384615
Subtract 260 from 280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7698.90384615, with a leftover of 2e-08.
