144156 ÷ 42 
The aim is to understand the frequency of 42 in 144156.

Moving on to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 42

Let's proceed to step 2:
42 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 42

Going ahead to step 3:
42 can be fit into 144 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 126 away from 144, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 42

Let's proceed to step 4:
42 can be fit into 181 4 times, resulting in a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 168 from 181 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 42

Advancing to step 5:
When dividing 135 by 42, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
If we subtract 126 from 135, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 42

Let's proceed to step 6:
96 divided by 42 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3432.0
If we take 84 away from 96, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 42, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3432.2
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3432.28
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3432.285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 42 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3432.2857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 3432.28571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 3432.285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3432.2857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3432.28571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3432.28571428 and a remainder of 2.4e-08.
