We're dividing 428738 by 42 
Our goal is to divide 428738 by 42.

Step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 42

Advancing to step 2:
If we divide 42 by 42, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 42 from 42.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 42

Step 3:
42 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 42

Going ahead to step 4:
42 can be fit into 87 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 84 from 87, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 42

Going ahead to step 5:
The number 42 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
If we take 0 away from 33, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 42

On to step 6:
The number 42 fits into 338 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 10208.0
Deduct 336 from 338 and we're left 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.

Moving on to step 7:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10208.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 10208.04
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 10208.047
If we take 294 away from 320, we end up 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.

Advancing to step 10:
If we divide 260 by 42, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10208.0476
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.

Advancing to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 10208.04761
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.

Going ahead to step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 10208.047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10208.047619
Deduct 0 from 20 and we're left with 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 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 10208.04761904
Subtracting 168 from 200 leaves us 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.

The final outcome is 10208.04761904, with a leftover of 3.2e-08.
