402671 ÷ 52 
The aim is to understand the frequency of 52 in 402671.

Going ahead to step 1:
52 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 52

Step 2:
When dividing 40 by 52, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 52

Step 3:
52 goes into 402 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 364 from 402 to get 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 52

Going ahead to step 4:
If we divide 386 by 52, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 22 after subtracting 364 from 386.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 52

Moving on to step 5:
227 divided by 52 is 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 774.0
If we subtract 208 from 227, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 52

Going ahead to step 6:
If we divide 191 by 52, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 7743.0
Subtract 156 from 191 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
If we divide 350 by 52, we get 6 and a remainder of 38.
The next digit of our result is 6. 
Result so far: 7743.6
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 52, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7743.67
If we take 364 away from 380, 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 9:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 7743.673
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 10:
52 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 7743.673
The remainder is 40 after subtracting 0 from 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 11:
If we divide 400 by 52, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 7743.67307
Subtract 364 from 400 to get 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 12:
52 goes into 360 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7743.673076
If we subtract 312 from 360, we 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.

Let's proceed to step 13:
If we divide 480 by 52, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 7743.6730769
The remainder is 12 after subtracting 468 from 480.
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 14:
If we divide 120 by 52, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 7743.67307692
Deduct 104 from 120 and we're left 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.

The final outcome is 7743.67307692, with a leftover of 1.6e-08.
