We look at the division of 785153 by 42 
Our goal is to divide 785153 by 42.

Step 1:
7 divided by 42 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Moving on to step 2:
If we divide 78 by 42, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 78 to get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 42

Let's proceed to step 3:
When dividing 365 by 42, we get 8 with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 336 from 365 to get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 42

Moving on to step 4:
When dividing 291 by 42, we get 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we subtract 252 from 291, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 42

On to step 5:
42 goes into 395 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 1869.0
Subtracting 378 from 395 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 42

Going ahead to step 6:
42 can be fit into 173 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 18694.0
The remainder is 5 after subtracting 168 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
42 goes into 50 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 18694.1
Subtracting 42 from 50 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.

Moving on to step 8:
42 goes into 80 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 18694.11
Deduct 42 from 80 and we're left 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.

Our division results in 18694.11 with a remaining 0.038.
