Let's divide 18753757 by 502
The aim is to understand the frequency of 502 in 18753757.

Going ahead to step 1:
502 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 502

Moving on to step 2:
The number 502 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 502

On to step 3:
If we divide 187 by 502, we get 0 and a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 187 and we're left with 187.
Take the next digit (5) from the dividend and append it to 187, then repeat: 1875 / 502

Moving on to step 4:
502 goes into 1875 3 times with a remainder of 369.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1506 from 1875 to get 369.
Grab the next digit (3) from the dividend, add it to 369, then carry on: 3693 / 502

Going ahead to step 5:
The number 502 fits into 3693 7 times, leaving a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 179 after subtracting 3514 from 3693.
Grab the next digit (7) from the dividend, add it to 179, then carry on: 1797 / 502

Going ahead to step 6:
The number 502 fits into 1797 3 times, leaving a remainder of 291.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
Subtracting 1506 from 1797 leaves us with 291.
Append the next digit (5) from the dividend to 291 and continue with: 2915 / 502

Going ahead to step 7:
If we divide 2915 by 502, we get 5 and a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 3735.0
If we take 2510 away from 2915, we end up with 405.
Grab the next digit (7) from the dividend, add it to 405, then carry on: 4057 / 502

On to step 8:
The number 502 fits into 4057 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 37358.0
If we take 4016 away from 4057, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
410 divided by 502 is 0 with a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 37358.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
4100 divided by 502 is 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 37358.08
The remainder is 84 after subtracting 4016 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
If we divide 840 by 502, we get 1 and a remainder of 338.
The number 1 becomes the next digit in our result. 
Result so far: 37358.081
If we take 502 away from 840, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 12:
502 goes into 3380 6 times with a remainder of 368.
Write down 6 as next digit of the result. 
Result so far: 37358.0816
If we subtract 3012 from 3380, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
When dividing 3680 by 502, we get 7 with a remainder of 166.
Put 7 as the next digit of the answer. 
Result so far: 37358.08167
If we subtract 3514 from 3680, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 14:
502 goes into 1660 3 times with a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 37358.081673
If we take 1506 away from 1660, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 15:
If we divide 1540 by 502, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 37358.0816733
Deduct 1506 from 1540 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 37358.0816733 and a remainder of 3.4e-07.
