We're dividing 787484 by 42 
We're looking to find how many times 42 goes into 787484.

On to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Moving on to step 2:
The number 42 fits into 78 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 78, we end up with 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 42

On to step 3:
42 goes into 367 8 times with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 336 away from 367, we end up with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 42

Advancing to step 4:
If we divide 314 by 42, we get 7 and a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
Subtracting 294 from 314 leaves us with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 42

Let's proceed to step 5:
When dividing 208 by 42, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 1874.0
The remainder is 40 after subtracting 168 from 208.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 42

Going ahead to step 6:
The number 42 fits into 404 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 18749.0
Subtracting 378 from 404 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
42 goes into 260 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 18749.6
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
If we divide 80 by 42, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 18749.61
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 18749.619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 18749.619
If we subtract 0 from 20, we 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.

Let's proceed to step 11:
200 divided by 42 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 18749.61904
Deduct 168 from 200 and we're left 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.

Step 12:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 18749.619047
If we subtract 294 from 320, we 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 13:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 18749.6190476
Deduct 252 from 260 and we're left 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.

Going ahead to step 14:
If we divide 80 by 42, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 18749.61904761
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.

The final result is 18749.61904761 with a remainder of 3.8e-08.
