406407 divided by 52 
The aim is to understand the frequency of 52 in 406407.

Advancing to step 1:
When dividing 4 by 52, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 52

Moving on to step 2:
52 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 52

Going ahead to step 3:
When dividing 406 by 52, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 364 from 406 and we're left with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 52

Step 4:
If we divide 424 by 52, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 416 away from 424, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 52

On to step 5:
80 divided by 52 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 781.0
Subtract 52 from 80 to get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 52

Moving on to step 6:
52 can be fit into 287 5 times, resulting in a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 7815.0
If we subtract 260 from 287, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 52, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7815.5
The remainder is 10 after subtracting 260 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
52 goes into 100 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 7815.51
Subtract 52 from 100 to get 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 9:
If we divide 480 by 52, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 7815.519
Subtracting 468 from 480 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.

Moving on to step 10:
120 divided by 52 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 7815.5192
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.

On to step 11:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 7815.51923
If we subtract 156 from 160, we 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.

Moving on to step 12:
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: 7815.51923
If we take 0 away from 40, we end up 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.

Advancing to step 13:
If we divide 400 by 52, we get 7 and a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7815.5192307
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.

Going ahead to step 14:
52 can be fit into 360 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7815.51923076
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.

Our division results in 7815.51923076 with a remaining 4.8e-08.
