920872 divided by 52 
The aim is to understand the frequency of 52 in 920872.

Step 1:
If we divide 9 by 52, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 52

Going ahead to step 2:
92 divided by 52 is 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 52 from 92 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 52

Going ahead to step 3:
52 goes into 400 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 364 from 400, we get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 52

Moving on to step 4:
52 can be fit into 368 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 177.0
Deduct 364 from 368 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 52

Step 5:
If we divide 47 by 52, we get 0 and a remainder of 47.
The next digit of our result is 0. 
Result so far: 1770.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 52

Step 6:
472 divided by 52 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 17709.0
Deduct 468 from 472 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.

Advancing to step 7:
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: 17709.0
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 8:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 17709.07
If we subtract 364 from 400, we 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.

Let's proceed to step 9:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 17709.076
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.

On to step 10:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 17709.0769
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.

Moving on to step 11:
52 can be fit into 120 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 17709.07692
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.

Advancing to step 12:
When dividing 160 by 52, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 17709.076923
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.

Let's proceed 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: 17709.076923
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 14:
52 goes into 400 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 17709.07692307
Deduct 364 from 400 and we're left 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.

The final outcome is 17709.07692307, with a leftover of 3.6e-08.
