51909741 divided by 502 
The aim is to understand the frequency of 502 in 51909741.

Let's proceed to step 1:
5 divided by 502 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 502

Going ahead to step 2:
51 divided by 502 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 502

On to step 3:
502 can be fit into 519 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 502 from 519 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 502

Advancing to step 4:
When dividing 170 by 502, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 170, we end up with 170.
Append the next digit (9) from the dividend to 170 and continue with: 1709 / 502

Advancing to step 5:
502 can be fit into 1709 3 times, resulting in a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtract 1506 from 1709 to get 203.
Bring next digit (7) of the dividend behind the 203 and repeat the process: 2037 / 502

Going ahead to step 6:
The number 502 fits into 2037 4 times, leaving a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1034.0
Subtract 2008 from 2037 to get 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 502

Going ahead to step 7:
The number 502 fits into 294 0 times, leaving a remainder of 294.
Put 0 as the next digit of the answer. 
Result so far: 10340.0
Subtract 0 from 294 to get 294.
Fetch the next digit (1) from the dividend, attach it to 294 and continue: 2941 / 502

On to step 8:
If we divide 2941 by 502, we get 5 and a remainder of 431.
Use 5 as the next digit of our solution. 
Result so far: 103405.0
Subtract 2510 from 2941 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 9:
If we divide 4310 by 502, we get 8 and a remainder of 294.
Put 8 as the next digit of the answer. 
Result so far: 103405.8
Deduct 4016 from 4310 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
502 goes into 2940 5 times with a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 103405.85
Subtract 2510 from 2940 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
When dividing 4300 by 502, we get 8 with a remainder of 284.
Record the quotient 8 as the next digit in the result. 
Result so far: 103405.858
If we subtract 4016 from 4300, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 12:
502 goes into 2840 5 times with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 103405.8585
Subtract 2510 from 2840 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 13:
The number 502 fits into 3300 6 times, leaving a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 103405.85856
If we take 3012 away from 3300, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
502 can be fit into 2880 5 times, resulting in a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 103405.858565
Subtracting 2510 from 2880 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 15:
If we divide 3700 by 502, we get 7 and a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 103405.8585657
The remainder is 186 after subtracting 3514 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 16:
When dividing 1860 by 502, we get 3 with a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 103405.85856573
If we take 1506 away from 1860, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 103405.85856573 with a balance of 3.54e-07.
