We're dividing 782821 by 52 
The aim is to understand the frequency of 52 in 782821.

Advancing to step 1:
52 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 52

Moving on to step 2:
78 divided by 52 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
If we take 52 away from 78, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 52

Moving on to step 3:
52 can be fit into 262 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 260 away from 262, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 52

Moving on to step 4:
28 divided by 52 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 52

Step 5:
If we divide 282 by 52, we get 5 and a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 1505.0
Subtract 260 from 282 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 52

Advancing to step 6:
When dividing 221 by 52, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 15054.0
If we take 208 away from 221, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
52 can be fit into 130 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 15054.2
Subtract 104 from 130 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
The number 52 fits into 260 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 15054.25
Subtract 260 from 260 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
52 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15054.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
52 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15054.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15054.25 with a remaining 0.0.
