We're dividing 788430 by 42 
We're looking to find how many times 42 goes into 788430.

Moving on to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
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:
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
Subtracting 42 from 78 leaves us with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 42

Let's proceed to step 3:
368 divided by 42 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 336 away from 368, we end up with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 42

Going ahead to step 4:
42 goes into 324 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 187.0
The remainder is 30 after subtracting 294 from 324.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 42

Moving on to step 5:
The number 42 fits into 303 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1877.0
The remainder is 9 after subtracting 294 from 303.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 42

Moving on to step 6:
42 can be fit into 90 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 18772.0
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 18772.1
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 18772.14
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 18772.142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 18772.1428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
42 goes into 240 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 18772.14285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 18772.142857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 18772.1428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18772.14285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 18772.14285714 and a remainder of 1.2e-08.
