486417 divided by 42 
The aim is to understand the frequency of 42 in 486417.

Step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 42

On to step 2:
If we divide 48 by 42, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 48, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 42

Let's proceed to step 3:
The number 42 fits into 66 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 42 away from 66, we end up with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 42

Advancing to step 4:
If we divide 244 by 42, we get 5 and a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we take 210 away from 244, we end up with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 42

On to step 5:
When dividing 341 by 42, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 1158.0
Subtract 336 from 341 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 42

Let's proceed to step 6:
The number 42 fits into 57 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11581.0
The remainder is 15 after subtracting 42 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 42, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 11581.3
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11581.35
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 11581.357
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 11581.3571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 11581.35714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 11581.357142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
When dividing 360 by 42, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 11581.3571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11581.35714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 11581.35714285, with a leftover of 3e-08.
