384859 ÷ 42 
The aim is to understand the frequency of 42 in 384859.

Going ahead to step 1:
3 divided by 42 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 42

On to step 2:
38 divided by 42 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 42

Going ahead to step 3:
42 goes into 384 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 378 from 384 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 42

On to step 4:
The number 42 fits into 68 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 42 from 68 and we're left with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 42

Moving on to step 5:
42 can be fit into 265 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 916.0
If we subtract 252 from 265, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 42

Moving on to step 6:
42 goes into 139 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 9163.0
If we subtract 126 from 139, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 42, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9163.3
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9163.3
Deduct 0 from 40 and we're left 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.

Advancing to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 9163.309
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 42, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9163.3095
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.

On to step 11:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9163.30952
Deduct 84 from 100 and we're left 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 12:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 9163.309523
The remainder is 34 after subtracting 126 from 160.
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:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9163.3095238
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9163.3095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 9163.3095238 with a remaining 4e-08.
