Let's divide 210722 by 42
The aim is to understand the frequency of 42 in 210722.

Moving on to 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
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 42

Let's proceed to step 2:
42 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 42

Moving on to step 3:
When dividing 210 by 42, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 210 from 210.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 42

On to step 4:
7 divided by 42 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

Step 5:
When dividing 72 by 42, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 501.0
The remainder is 30 after subtracting 42 from 72.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 42

On to step 6:
The number 42 fits into 302 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 5017.0
The remainder is 8 after subtracting 294 from 302.
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:
42 goes into 80 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 5017.1
Deduct 42 from 80 and we're left 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:
42 goes into 380 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 5017.19
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.

Step 9:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5017.19
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 10:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 5017.1904
Subtracting 168 from 200 leaves us 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 11:
When dividing 320 by 42, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 5017.19047
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.

On to step 12:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 5017.190476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
When dividing 80 by 42, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 5017.1904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 5017.19047619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 5017.19047619 with a remaining 2e-09.
