409621 ÷ 52 
The aim is to understand the frequency of 52 in 409621.

Moving on to step 1:
52 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 52

Advancing to step 2:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 52

Step 3:
409 divided by 52 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 364 from 409 and we're left with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 52

Going ahead to step 4:
When dividing 456 by 52, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 416 from 456 and we're left with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 52

On to step 5:
If we divide 402 by 52, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 787.0
If we take 364 away from 402, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 52

On to step 6:
52 can be fit into 381 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 7877.0
If we take 364 away from 381, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
52 can be fit into 170 3 times, resulting in a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 7877.3
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 52 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 7877.32
Subtract 104 from 140 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.

On to step 9:
When dividing 360 by 52, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 7877.326
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 10:
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: 7877.3269
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
If we divide 120 by 52, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7877.32692
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.

Let's proceed to step 12:
When dividing 160 by 52, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7877.326923
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
52 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7877.326923
Subtracting 0 from 40 leaves us 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.

Step 14:
When dividing 400 by 52, we get 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7877.32692307
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.

In conclusion, the division gives 7877.32692307 with a balance of 3.6e-08.
