The aim is to understand the frequency of 423 in 53365065.

Moving on to step 1:
5 divided by 423 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 423

Moving on to step 2:
423 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 423

Step 3:
The number 423 fits into 533 1 times, leaving a remainder of 110.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 423 away from 533, we end up with 110.
Append the next digit (6) from the dividend to 110 and continue with: 1106 / 423

Step 4:
1106 divided by 423 is 2 with a remainder of 260.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 846 away from 1106, we end up with 260.
Fetch the next digit (5) from the dividend, attach it to 260 and continue: 2605 / 423

Moving on to step 5:
423 goes into 2605 6 times with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Deduct 2538 from 2605 and we're left with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 423

Advancing to step 6:
423 can be fit into 670 1 times, resulting in a remainder of 247.
The next digit of our result is 1. 
Result so far: 1261.0
Deduct 423 from 670 and we're left with 247.
Append the next digit (6) from the dividend to 247 and continue with: 2476 / 423

On to step 7:
When dividing 2476 by 423, we get 5 with a remainder of 361.
The next digit of our result is 5. 
Result so far: 12615.0
If we take 2115 away from 2476, we end up with 361.
Fetch the next digit (5) from the dividend, attach it to 361 and continue: 3615 / 423

Moving on to step 8:
The number 423 fits into 3615 8 times, leaving a remainder of 231.
The next digit of our result is 8. 
Result so far: 126158.0
Deduct 3384 from 3615 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
The number 423 fits into 2310 5 times, leaving a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 126158.5
If we take 2115 away from 2310, we end up 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 10:
If we divide 1950 by 423, we get 4 and a remainder of 258.
The next digit of our result is 4. 
Result so far: 126158.54
If we take 1692 away from 1950, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 11:
If we divide 2580 by 423, we get 6 and a remainder of 42.
The next digit of our result is 6. 
Result so far: 126158.546
Subtracting 2538 from 2580 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
420 divided by 423 is 0 with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 126158.546
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 13:
4200 divided by 423 is 9 with a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 126158.54609
If we take 3807 away from 4200, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 14:
When dividing 3930 by 423, we get 9 with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 126158.546099
Subtracting 3807 from 3930 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Our division results in 126158.546099 with a remaining 1.23e-05.
