Let's divide 21296 by 42
The aim is to understand the frequency of 42 in 21296.

Let's proceed to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 42

Advancing to step 2:
The number 42 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 42

Let's proceed to step 3:
The number 42 fits into 212 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 210 from 212 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 42

Going ahead to step 4:
When dividing 29 by 42, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtract 0 from 29 to get 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 42

Going ahead to step 5:
42 can be fit into 296 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we take 294 away from 296, we end up 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.

Let's proceed to step 6:
When dividing 20 by 42, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 507.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 507.04
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
42 goes into 320 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 507.047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 507.0476
If we take 252 away from 260, we end up 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.

Let's proceed to step 10:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 507.04761
If we take 42 away from 80, we end up 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 11:
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: 507.047619
Subtracting 378 from 380 leaves us 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.

Let's proceed to step 12:
20 divided by 42 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 507.047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
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: 507.04761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 507.04761904, and the remainder is 3.2e-08.
