Let's divide 617423 by 42
The aim is to understand the frequency of 42 in 617423.

Going ahead to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 42

Moving on to step 2:
If we divide 61 by 42, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 61 and we're left with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 42

Let's proceed to step 3:
197 divided by 42 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 168 from 197 leaves us with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 42

Moving on to step 4:
If we divide 294 by 42, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 294 from 294 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 42

Advancing to step 5:
2 divided by 42 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1470.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

Advancing to step 6:
23 divided by 42 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 14700.0
Subtract 0 from 23 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
42 can be fit into 230 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 14700.5
If we subtract 210 from 230, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 14700.54
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 14700.547
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 14700.5476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 14700.54761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 14700.547619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 14700.547619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 42 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 14700.54761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 14700.54761904 with a remaining 3.2e-08.
