We divide 156781 by 42
The aim is to understand the frequency of 42 in 156781.

Let's proceed to 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
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 42

On to step 2:
When dividing 15 by 42, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 42

On to step 3:
42 goes into 156 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 126 away from 156, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 42

Let's proceed to step 4:
The number 42 fits into 307 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 294 from 307 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 42

Advancing to step 5:
42 goes into 138 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 373.0
Subtract 126 from 138 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 42

Let's proceed to step 6:
121 divided by 42 is 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 3732.0
Deduct 84 from 121 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
When dividing 370 by 42, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 3732.8
If we subtract 336 from 370, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3732.88
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 3732.88 with a remaining 0.004.
