72566722 ÷ 502 
The aim is to understand the frequency of 502 in 72566722.

On to step 1:
The number 502 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 502

On to step 2:
502 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 502

On to step 3:
When dividing 725 by 502, we get 1 with a remainder of 223.
The next digit of our result is 1. 
Result so far: 1.0
If we take 502 away from 725, we end up with 223.
Append the next digit (6) from the dividend to 223 and continue with: 2236 / 502

Advancing to step 4:
If we divide 2236 by 502, we get 4 and a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2008 from 2236 and we're left with 228.
Bring next digit (6) of the dividend behind the 228 and repeat the process: 2286 / 502

Let's proceed to step 5:
502 can be fit into 2286 4 times, resulting in a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we take 2008 away from 2286, we end up with 278.
Fetch the next digit (7) from the dividend, attach it to 278 and continue: 2787 / 502

Moving on to step 6:
When dividing 2787 by 502, we get 5 with a remainder of 277.
The number 5 becomes the next digit in our result. 
Result so far: 1445.0
Deduct 2510 from 2787 and we're left with 277.
Append the next digit (2) from the dividend to 277 and continue with: 2772 / 502

Moving on to step 7:
The number 502 fits into 2772 5 times, leaving a remainder of 262.
Put 5 as the next digit of the answer. 
Result so far: 14455.0
If we take 2510 away from 2772, we end up with 262.
Bring next digit (2) of the dividend behind the 262 and repeat the process: 2622 / 502

Going ahead to step 8:
2622 divided by 502 is 5 with a remainder of 112.
Write down 5 as next digit of the result. 
Result so far: 144555.0
If we take 2510 away from 2622, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
1120 divided by 502 is 2 with a remainder of 116.
The next digit of our result is 2. 
Result so far: 144555.2
The remainder is 116 after subtracting 1004 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
The number 502 fits into 1160 2 times, leaving a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 144555.22
Subtracting 1004 from 1160 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The quotient of the division is 144555.22, and the remainder is 0.156.
