We divide 23340439 by 42
The aim is to understand the frequency of 42 in 23340439.

Moving on to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

Moving on to step 2:
42 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 42

Moving on to step 3:
42 goes into 233 5 times with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 210 from 233 leaves us with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 42

Let's proceed to step 4:
If we divide 234 by 42, we get 5 and a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 210 from 234 leaves us with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 42

Advancing to step 5:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 555.0
If we subtract 210 from 240, we get 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 42

Let's proceed to step 6:
The number 42 fits into 304 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 5557.0
If we subtract 294 from 304, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 42

Advancing to step 7:
The number 42 fits into 103 2 times, leaving a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 55572.0
Deduct 84 from 103 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 42

Going ahead to step 8:
If we divide 199 by 42, we get 4 and a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 555724.0
Subtract 168 from 199 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.

Moving on to step 9:
42 can be fit into 310 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 555724.7
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 555724.73
Subtracting 126 from 160 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.

On to step 11:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 555724.738
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 555724.738
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 555724.73809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 555724.738095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 555724.7380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 555724.73809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 555724.73809523 with a remaining 3.4e-08.
