290461 divided by 42 
The aim is to understand the frequency of 42 in 290461.

Step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 42

Let's proceed to step 2:
If we divide 29 by 42, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 42

Going ahead to step 3:
42 can be fit into 290 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 252 from 290 leaves us with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 42

Let's proceed to step 4:
When dividing 384 by 42, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 378 from 384 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 42

Let's proceed to step 5:
66 divided by 42 is 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 691.0
Subtract 42 from 66 to get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 42

Let's proceed to step 6:
42 can be fit into 241 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 6915.0
If we subtract 210 from 241, we 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 7:
310 divided by 42 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 6915.7
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 6915.73
Subtract 126 from 160 to 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.

Let's proceed to step 9:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 6915.738
If we take 336 away from 340, we end up 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 10:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6915.738
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.

On to step 11:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 6915.73809
Subtract 378 from 400 to 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.

Going ahead to step 12:
42 goes into 220 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6915.738095
If we take 210 away from 220, we end up 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.

Moving on to step 13:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 6915.7380952
If we take 84 away from 100, we end up 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.

Going ahead to step 14:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 6915.73809523
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 6915.73809523 with a remaining 3.4e-08.
