We're dividing 971920 by 52 
The aim is to understand the frequency of 52 in 971920.

Step 1:
9 divided by 52 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 52

On to step 2:
When dividing 97 by 52, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 52 from 97 and we're left with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 52

On to step 3:
If we divide 451 by 52, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 416 from 451 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 52

Going ahead to step 4:
The number 52 fits into 359 6 times, leaving a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we subtract 312 from 359, we get 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 52

Advancing to step 5:
52 can be fit into 472 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 1869.0
Subtract 468 from 472 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 52

Step 6:
52 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 18690.0
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.

Moving on to step 7:
400 divided by 52 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 18690.7
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.

Going ahead to step 8:
If we divide 360 by 52, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 18690.76
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 9:
The number 52 fits into 480 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 18690.769
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.

Going ahead to step 10:
When dividing 120 by 52, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 18690.7692
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.

Step 11:
If we divide 160 by 52, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 18690.76923
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.

On to step 12:
52 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 18690.76923
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.

Going ahead to step 13:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 18690.7692307
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.

Moving on to step 14:
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: 18690.76923076
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.

The final outcome is 18690.76923076, with a leftover of 4.8e-08.
