We're dividing 851462 by 42 
The aim is to understand the frequency of 42 in 851462.

On to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 42

Moving on to step 2:
42 can be fit into 85 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 84 from 85 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 42

Let's proceed to step 3:
42 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 42

Step 4:
When dividing 114 by 42, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtract 84 from 114 to get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 42

Moving on to step 5:
The number 42 fits into 306 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 2027.0
Deduct 294 from 306 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 42

Step 6:
When dividing 122 by 42, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 20272.0
If we subtract 84 from 122, we 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.

Going ahead to step 7:
When dividing 380 by 42, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 20272.9
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.

Moving on to step 8:
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: 20272.9
Subtract 0 from 20 to 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.

Advancing to step 9:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 20272.904
Subtracting 168 from 200 leaves us 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.

Going ahead to step 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 20272.9047
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.

Step 11:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 20272.90476
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.

On to step 12:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 20272.904761
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.

Step 13:
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: 20272.9047619
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.

Step 14:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20272.9047619
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.

In conclusion, the division gives 20272.9047619 with a balance of 2e-08.
