We're dividing 850834 by 42 
The aim is to understand the frequency of 42 in 850834.

Step 1:
42 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 42

Let's proceed to step 2:
85 divided by 42 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 84 from 85 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 42

Let's proceed to step 3:
10 divided by 42 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 10 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 42

Going ahead to step 4:
42 can be fit into 108 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Subtracting 84 from 108 leaves us with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 42

Going ahead to step 5:
42 goes into 243 5 times with a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 2025.0
Subtracting 210 from 243 leaves us with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 42

Let's proceed to step 6:
42 can be fit into 334 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 20257.0
If we take 294 away from 334, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 20257.9
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20257.95
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20257.952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 20257.9523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 20257.95238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20257.95238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 42, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 20257.9523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20257.95238095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 20257.95238095 with a balance of 1e-08.
