We're dividing 66240922 by 502 
The aim is to understand the frequency of 502 in 66240922.

Let's proceed to step 1:
When dividing 6 by 502, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 502

Let's proceed to step 2:
502 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 502

Step 3:
If we divide 662 by 502, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 160 after subtracting 502 from 662.
Fetch the next digit (4) from the dividend, attach it to 160 and continue: 1604 / 502

Let's proceed to step 4:
If we divide 1604 by 502, we get 3 and a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1506 from 1604, we get 98.
Take the next digit (0) from the dividend and append it to 98, then repeat: 980 / 502

Moving on to step 5:
The number 502 fits into 980 1 times, leaving a remainder of 478.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we subtract 502 from 980, we get 478.
Bring next digit (9) of the dividend behind the 478 and repeat the process: 4789 / 502

Advancing to step 6:
When dividing 4789 by 502, we get 9 with a remainder of 271.
The next digit of our result is 9. 
Result so far: 1319.0
Deduct 4518 from 4789 and we're left with 271.
Bring next digit (2) of the dividend behind the 271 and repeat the process: 2712 / 502

Let's proceed to step 7:
The number 502 fits into 2712 5 times, leaving a remainder of 202.
The number 5 becomes the next digit in our result. 
Result so far: 13195.0
If we subtract 2510 from 2712, we get 202.
Bring next digit (2) of the dividend behind the 202 and repeat the process: 2022 / 502

On to step 8:
If we divide 2022 by 502, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 131954.0
Subtracting 2008 from 2022 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
502 goes into 140 0 times with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 131954.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
502 goes into 1400 2 times with a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 131954.02
Subtract 1004 from 1400 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 11:
502 goes into 3960 7 times with a remainder of 446.
Use 7 as the next digit of our solution. 
Result so far: 131954.027
Subtracting 3514 from 3960 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 12:
When dividing 4460 by 502, we get 8 with a remainder of 444.
The number 8 becomes the next digit in our result. 
Result so far: 131954.0278
If we take 4016 away from 4460, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 13:
The number 502 fits into 4440 8 times, leaving a remainder of 424.
The next digit of our result is 8. 
Result so far: 131954.02788
If we subtract 4016 from 4440, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 131954.02788, with a leftover of 0.000424.
