Let's divide 507225 by 53
The aim is to understand the frequency of 53 in 507225.

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
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 53

Let's proceed to step 2:
50 divided by 53 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 53

Moving on to step 3:
53 goes into 507 9 times with a remainder of 30.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 30 after subtracting 477 from 507.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 53

Going ahead to step 4:
53 goes into 302 5 times with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 265 away from 302, we end up with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 53

Advancing to step 5:
53 goes into 372 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 957.0
Subtracting 371 from 372 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 53

Going ahead to step 6:
The number 53 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 9570.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
53 goes into 150 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 9570.2
Deduct 106 from 150 and we're left 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.

Let's proceed to step 8:
53 goes into 440 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 9570.28
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.

Let's proceed to step 9:
When dividing 160 by 53, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 9570.283
Subtract 159 from 160 to 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.

Moving on to step 10:
When dividing 10 by 53, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 9570.283
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 53 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 9570.28301
If we subtract 53 from 100, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
If we divide 470 by 53, we get 8 and a remainder of 46.
The next digit of our result is 8. 
Result so far: 9570.283018
Deduct 424 from 470 and we're left 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.

Step 13:
If we divide 460 by 53, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 9570.2830188
Deduct 424 from 460 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 9570.2830188, with a leftover of 3.6e-07.
