We look at the division of 836472 by 42 
We want to divide 836472 by 42.

Let's proceed to step 1:
42 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 42

Step 2:
When dividing 83 by 42, we get 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 83 and we're left with 41.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 42

On to step 3:
42 goes into 416 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 378 from 416, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 42

On to step 4:
42 can be fit into 384 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 199.0
The remainder is 6 after subtracting 378 from 384.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 42

Going ahead to step 5:
67 divided by 42 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1991.0
If we subtract 42 from 67, we get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 42

Step 6:
If we divide 252 by 42, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 19916.0
If we subtract 252 from 252, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
42 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19916.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19916.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 19916.0, with a leftover of 0.0.
