We look at the division of 78785 by 42 
We want to figure out the number of times 78785 can be divided by 42.

Going ahead to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 42

Let's proceed to step 2:
If we divide 78 by 42, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 78 to get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 42

Step 3:
42 goes into 367 8 times with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 31 after subtracting 336 from 367.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 42

Going ahead to step 4:
When dividing 318 by 42, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Deduct 294 from 318 and we're left with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 42

Advancing to step 5:
245 divided by 42 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1875.0
The remainder is 35 after subtracting 210 from 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 6:
42 goes into 350 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1875.8
If we subtract 336 from 350, we 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.

Step 7:
If we divide 140 by 42, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 1875.83
If we subtract 126 from 140, we 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.

Advancing to step 8:
42 goes into 140 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 1875.833
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.

After the division, we end up with 1875.833 and a remainder of 0.0014.
