398880 divided by 52 
The aim is to understand the frequency of 52 in 398880.

Advancing to step 1:
3 divided by 52 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 52

Advancing to step 2:
39 divided by 52 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 52

Moving on to step 3:
The number 52 fits into 398 7 times, leaving a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 364 away from 398, we end up with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 52

Moving on to step 4:
52 goes into 348 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 36 after subtracting 312 from 348.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 52

Let's proceed to step 5:
368 divided by 52 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 767.0
Subtract 364 from 368 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 52

Let's proceed to step 6:
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: 7670.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
400 divided by 52 is 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7670.7
Subtracting 364 from 400 leaves us with 36.
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 8:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 7670.76
If we take 312 away from 360, we end up 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.

Step 9:
When dividing 480 by 52, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 7670.769
Deduct 468 from 480 and we're left 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:
52 can be fit into 120 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 7670.7692
If we subtract 104 from 120, we 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.

Going ahead to step 11:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7670.76923
Deduct 156 from 160 and we're left 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.

Moving on to step 12:
If we divide 40 by 52, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7670.76923
If we subtract 0 from 40, we get 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 13:
When dividing 400 by 52, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7670.7692307
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
52 goes into 360 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7670.76923076
Subtract 312 from 360 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.

Our division results in 7670.76923076 with a remaining 4.8e-08.
