We're dividing 620837 by 42 
Our goal is to divide 620837 by 42.

Moving on to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 42

Going ahead to step 2:
The number 42 fits into 62 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 62 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 42

Going ahead to step 3:
When dividing 200 by 42, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 168 from 200 and we're left with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 42

Let's proceed to step 4:
328 divided by 42 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 147.0
Deduct 294 from 328 and we're left with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 42

Going ahead to step 5:
343 divided by 42 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 1478.0
Subtract 336 from 343 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 42

Going ahead to step 6:
42 goes into 77 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 14781.0
If we subtract 42 from 77, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
If we divide 350 by 42, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 14781.8
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 8:
When dividing 140 by 42, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 14781.83
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.

On to step 9:
140 divided by 42 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 14781.833
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 14781.833 and a remainder of 0.0014.
