We're dividing 502749 by 53 
The aim is to understand the frequency of 53 in 502749.

Advancing to step 1:
The number 53 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 53

On to step 2:
If we divide 50 by 53, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 53

Let's proceed to step 3:
53 goes into 502 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 25 after subtracting 477 from 502.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 53

Advancing to step 4:
257 divided by 53 is 4 with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we take 212 away from 257, we end up with 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 53

Advancing to step 5:
The number 53 fits into 454 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 948.0
Subtracting 424 from 454 leaves us with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 53

Let's proceed to step 6:
When dividing 309 by 53, we get 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 9485.0
Subtracting 265 from 309 leaves us 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:
When dividing 440 by 53, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9485.8
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.

Moving on to step 8:
The number 53 fits into 160 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 9485.83
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 53, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9485.83
Deduct 0 from 10 and we're left 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:
53 goes into 100 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 9485.8301
The remainder is 47 after subtracting 53 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 9485.83018
Subtracting 424 from 470 leaves us 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:
When dividing 460 by 53, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9485.830188
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 9485.830188, and the remainder is 3.6e-06.
