1243347 divided by 505 
The aim is to understand the frequency of 505 in 1243347.

Moving on to step 1:
If we divide 1 by 505, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 505

Step 2:
12 divided by 505 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 505

On to step 3:
124 divided by 505 is 0 with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 505

Advancing to step 4:
The number 505 fits into 1243 2 times, leaving a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 233 after subtracting 1010 from 1243.
Take the next digit (3) from the dividend and append it to 233, then repeat: 2333 / 505

Advancing to step 5:
505 can be fit into 2333 4 times, resulting in a remainder of 313.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 2020 from 2333 to get 313.
Fetch the next digit (4) from the dividend, attach it to 313 and continue: 3134 / 505

Step 6:
505 goes into 3134 6 times with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtracting 3030 from 3134 leaves us with 104.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 505

Advancing to step 7:
1047 divided by 505 is 2 with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 2462.0
The remainder is 37 after subtracting 1010 from 1047.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 505, we get 0 and a remainder of 370.
The next digit of our result is 0. 
Result so far: 2462.0
Deduct 0 from 370 and we're left 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.

Moving on to step 9:
3700 divided by 505 is 7 with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 2462.07
If we take 3535 away from 3700, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
505 goes into 1650 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 2462.073
If we take 1515 away from 1650, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
When dividing 1350 by 505, we get 2 with a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 2462.0732
Subtract 1010 from 1350 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
When dividing 3400 by 505, we get 6 with a remainder of 370.
Put 6 as the next digit of the answer. 
Result so far: 2462.07326
If we subtract 3030 from 3400, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 13:
505 goes into 3700 7 times with a remainder of 165.
Write down 7 as next digit of the result. 
Result so far: 2462.073267
Deduct 3535 from 3700 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 14:
When dividing 1650 by 505, we get 3 with a remainder of 135.
The next digit of our result is 3. 
Result so far: 2462.0732673
If we take 1515 away from 1650, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
505 goes into 1350 2 times with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 2462.07326732
Deduct 1010 from 1350 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 2462.07326732 and a remainder of 3.4e-07.
