Let's divide 42145 by 69
The aim is to understand the frequency of 69 in 42145.

Step 1:
69 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 69

Advancing to step 2:
69 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 69

Moving on to step 3:
When dividing 421 by 69, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 414 from 421, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 69

Let's proceed to step 4:
When dividing 74 by 69, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we subtract 69 from 74, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 69

Advancing to step 5:
69 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 610.0
If we subtract 0 from 55, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 6:
When dividing 550 by 69, we get 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 610.7
If we subtract 483 from 550, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
The number 69 fits into 670 9 times, leaving a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 610.79
The remainder is 49 after subtracting 621 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
The number 69 fits into 490 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 610.797
Deduct 483 from 490 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
69 goes into 70 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 610.7971
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
When dividing 10 by 69, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 610.7971
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
69 can be fit into 100 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 610.797101
Subtract 69 from 100 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
When dividing 310 by 69, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 610.7971014
Subtracting 276 from 310 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 610.79710144
Subtracting 276 from 340 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 610.79710144, with a leftover of 6.4e-08.
