Let's divide 51539764 by 505
The aim is to understand the frequency of 505 in 51539764.

Advancing to step 1:
The number 505 fits into 5 0 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 505

On to step 2:
505 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 505

Advancing to step 3:
When dividing 515 by 505, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 505 from 515 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 505

Going ahead to step 4:
505 goes into 103 0 times with a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 103, we get 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 505

Advancing to step 5:
When dividing 1039 by 505, we get 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtracting 1010 from 1039 leaves us with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 505

Let's proceed to step 6:
505 goes into 297 0 times with a remainder of 297.
The number 0 becomes the next digit in our result. 
Result so far: 1020.0
The remainder is 297 after subtracting 0 from 297.
Grab the next digit (6) from the dividend, add it to 297, then carry on: 2976 / 505

Let's proceed to step 7:
2976 divided by 505 is 5 with a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 10205.0
If we take 2525 away from 2976, we end up with 451.
Bring next digit (4) of the dividend behind the 451 and repeat the process: 4514 / 505

On to step 8:
505 goes into 4514 8 times with a remainder of 474.
Use 8 as the next digit of our solution. 
Result so far: 102058.0
The remainder is 474 after subtracting 4040 from 4514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 9:
If we divide 4740 by 505, we get 9 and a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 102058.9
Deduct 4545 from 4740 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 10:
The number 505 fits into 1950 3 times, leaving a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 102058.93
If we take 1515 away from 1950, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 11:
When dividing 4350 by 505, we get 8 with a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 102058.938
The remainder is 310 after subtracting 4040 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
If we divide 3100 by 505, we get 6 and a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 102058.9386
If we take 3030 away from 3100, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
The number 505 fits into 700 1 times, leaving a remainder of 195.
The next digit of our result is 1. 
Result so far: 102058.93861
Subtracting 505 from 700 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 14:
When dividing 1950 by 505, we get 3 with a remainder of 435.
Record the quotient 3 as the next digit in the result. 
Result so far: 102058.938613
The remainder is 435 after subtracting 1515 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 15:
If we divide 4350 by 505, we get 8 and a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 102058.9386138
Subtracting 4040 from 4350 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
If we divide 3100 by 505, we get 6 and a remainder of 70.
The next digit of our result is 6. 
Result so far: 102058.93861386
Subtracting 3030 from 3100 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 102058.93861386 and a remainder of 7e-08.
