784051 divided by 42 
We want to divide 784051 by 42.

On to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 42

Going ahead to step 2:
If we divide 78 by 42, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 78, we end up with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 42

Step 3:
The number 42 fits into 364 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 336 from 364 and we're left with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 42

Step 4:
When dividing 280 by 42, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Subtract 252 from 280 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 42

Moving on to step 5:
42 can be fit into 285 6 times, resulting in a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 1866.0
If we subtract 252 from 285, we get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 42

Moving on to step 6:
42 can be fit into 331 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 18667.0
If we subtract 294 from 331, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 42 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 18667.8
If we subtract 336 from 370, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18667.88
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 18667.88, with a leftover of 0.004.
