52453478 divided by 502 
The aim is to understand the frequency of 502 in 52453478.

Let's proceed to step 1:
When dividing 5 by 502, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 502

Let's proceed to step 2:
The number 502 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 502

Going ahead to step 3:
524 divided by 502 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 502 from 524 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 502

Moving on to step 4:
502 goes into 225 0 times with a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 225, we get 225.
Bring next digit (3) of the dividend behind the 225 and repeat the process: 2253 / 502

Step 5:
502 can be fit into 2253 4 times, resulting in a remainder of 245.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 2008 from 2253 and we're left with 245.
Include the next digit (4) from the dividend after 245, then repeat: 2454 / 502

Moving on to step 6:
If we divide 2454 by 502, we get 4 and a remainder of 446.
Record the quotient 4 as the next digit in the result. 
Result so far: 1044.0
Subtract 2008 from 2454 to get 446.
Grab the next digit (7) from the dividend, add it to 446, then carry on: 4467 / 502

Moving on to step 7:
If we divide 4467 by 502, we get 8 and a remainder of 451.
The next digit of our result is 8. 
Result so far: 10448.0
If we take 4016 away from 4467, we end up with 451.
Fetch the next digit (8) from the dividend, attach it to 451 and continue: 4518 / 502

Moving on to step 8:
4518 divided by 502 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 104489.0
Deduct 4518 from 4518 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 502, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 104489.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 502, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 104489.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 104489.0 with a remaining 0.0.
