We're dividing 502007 by 53 
The aim is to understand the frequency of 53 in 502007.

Step 1:
The number 53 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 53

On to step 2:
53 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 53

Let's proceed to step 3:
502 divided by 53 is 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 9.0
If we take 477 away from 502, we end up with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 53

On to step 4:
When dividing 250 by 53, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
The remainder is 38 after subtracting 212 from 250.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 53

Step 5:
53 goes into 380 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 947.0
The remainder is 9 after subtracting 371 from 380.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 53

Going ahead to step 6:
53 goes into 97 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 9471.0
If we take 53 away from 97, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 53, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9471.8
Deduct 424 from 440 and we're left with 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 8:
53 goes into 160 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 9471.83
If we take 159 away from 160, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 53 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9471.83
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 53, we get 1 and a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 9471.8301
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
53 goes into 470 8 times with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 9471.83018
If we take 424 away from 470, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
53 goes into 460 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9471.830188
If we take 424 away from 460, 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.

The quotient of the division is 9471.830188, and the remainder is 3.6e-06.
