920289 divided by 42 
The aim is to understand the frequency of 42 in 920289.

Step 1:
42 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Moving on to step 2:
When dividing 92 by 42, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 84 from 92 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 42

On to step 3:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 42 from 80, we get 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 42

On to step 4:
42 goes into 382 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we take 378 away from 382, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 42

Step 5:
48 divided by 42 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 2191.0
The remainder is 6 after subtracting 42 from 48.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 42

Going ahead to step 6:
If we divide 69 by 42, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 21911.0
Subtracting 42 from 69 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
42 can be fit into 270 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 21911.6
Subtracting 252 from 270 leaves us 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 8:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 21911.64
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 21911.642
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 21911.6428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 21911.64285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 21911.642857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21911.6428571
Deduct 42 from 60 and we're left 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.

Let's proceed to step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 21911.64285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 21911.64285714 and a remainder of 1.2e-08.
