We look at the division of 207638 by 42 
The aim is to understand the frequency of 42 in 207638.

Let's proceed to step 1:
2 divided by 42 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 42

Step 2:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 42

Moving on to step 3:
When dividing 207 by 42, we get 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 168 from 207, we get 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 42

Step 4:
The number 42 fits into 396 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 378 from 396 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 42

Going ahead to step 5:
The number 42 fits into 183 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 494.0
Subtract 168 from 183 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 42

Going ahead to step 6:
If we divide 158 by 42, we get 3 and a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 4943.0
If we subtract 126 from 158, we 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.

Let's proceed to step 7:
If we divide 320 by 42, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 4943.7
Subtract 294 from 320 to 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.

Advancing to step 8:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4943.76
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.

Step 9:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 4943.761
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.

Advancing to step 10:
If we divide 380 by 42, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 4943.7619
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.

Let's proceed to step 11:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4943.7619
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.

On to step 12:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 4943.761904
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 13:
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: 4943.7619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 4943.76190476
Deduct 252 from 260 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.

The quotient of the division is 4943.76190476, and the remainder is 8e-09.
