135206 divided by 42 
The aim is to understand the frequency of 42 in 135206.

Moving on to step 1:
42 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 42

Moving on to step 2:
13 divided by 42 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 42

Going ahead to step 3:
If we divide 135 by 42, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 9 after subtracting 126 from 135.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 42

Advancing to step 4:
92 divided by 42 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtract 84 from 92 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 42

On to step 5:
If we divide 80 by 42, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtract 42 from 80 to get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 42

On to step 6:
If we divide 386 by 42, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 3219.0
Subtracting 378 from 386 leaves us 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.

Going ahead to step 7:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 3219.1
If we take 42 away from 80, we end up 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.

On to step 8:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 3219.19
Deduct 378 from 380 and we're left with 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 9:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3219.19
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.

Advancing to step 10:
200 divided by 42 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3219.1904
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.

Advancing to step 11:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 3219.19047
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 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: 3219.190476
Subtracting 252 from 260 leaves us 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.

Going ahead to step 13:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3219.1904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 3219.19047619
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.

In conclusion, the division gives 3219.19047619 with a balance of 2e-09.
