909392 ÷ 42 
The aim is to understand the frequency of 42 in 909392.

Advancing to step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 42

On to step 2:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 84 from 90 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 42

Step 3:
69 divided by 42 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 27 after subtracting 42 from 69.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 42

Moving on to step 4:
If we divide 273 by 42, we get 6 and a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtracting 252 from 273 leaves us with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 42

Let's proceed to step 5:
When dividing 219 by 42, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 2165.0
Deduct 210 from 219 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 42

Going ahead to step 6:
If we divide 92 by 42, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 21652.0
Deduct 84 from 92 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 42 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 21652.1
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 21652.19
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 21652.19
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 21652.1904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 21652.19047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
260 divided by 42 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 21652.190476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 21652.1904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 21652.19047619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 21652.19047619, with a leftover of 2e-09.
