785813 ÷ 42 
We want to figure out the number of times 785813 can be divided by 42.

Advancing to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 42

Moving on to step 2:
The number 42 fits into 78 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 36 after subtracting 42 from 78.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 42

Moving on to step 3:
When dividing 365 by 42, we get 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 336 from 365, we get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 42

Let's proceed to step 4:
When dividing 298 by 42, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
Subtracting 294 from 298 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 42

Moving on to step 5:
If we divide 41 by 42, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 1870.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 42

Going ahead to step 6:
The number 42 fits into 413 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 18709.0
Subtract 378 from 413 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
42 can be fit into 350 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 18709.8
The remainder is 14 after subtracting 336 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 42, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 18709.83
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
140 divided by 42 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 18709.833
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 18709.833 and a remainder of 0.0014.
