We divide 138452 by 42
The aim is to understand the frequency of 42 in 138452.

Step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Advancing to step 2:
42 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 42

Moving on to step 3:
42 goes into 138 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 126 from 138 and we're left with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 42

Advancing to step 4:
The number 42 fits into 124 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtract 84 from 124 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 42

Let's proceed to step 5:
42 can be fit into 405 9 times, resulting in a remainder of 27.
The next digit of our result is 9. 
Result so far: 329.0
The remainder is 27 after subtracting 378 from 405.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 42

Advancing to step 6:
272 divided by 42 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 3296.0
If we subtract 252 from 272, 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.

Going ahead to step 7:
200 divided by 42 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 3296.4
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.

Let's proceed to step 8:
320 divided by 42 is 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 3296.47
Subtracting 294 from 320 leaves us 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.

Advancing to step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3296.476
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.

Going ahead to step 10:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 3296.4761
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.

Moving on to step 11:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 3296.47619
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.

Advancing to step 12:
42 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3296.47619
If we take 0 away from 20, we end up with 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:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 3296.4761904
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.

Let's proceed to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 3296.47619047
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.

After the division, we end up with 3296.47619047 and a remainder of 2.6e-08.
