We're dividing 784492 by 42 
Our goal is to divide 784492 by 42.

On to step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the 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

Moving on to step 2:
42 goes into 78 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 78 and we're left with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 42

Advancing to step 3:
42 can be fit into 364 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 336 from 364 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 42

Step 4:
284 divided by 42 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we take 252 away from 284, we end up with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 42

Let's proceed to step 5:
329 divided by 42 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 1867.0
If we subtract 294 from 329, we get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 42

Step 6:
When dividing 352 by 42, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18678.0
The remainder is 16 after subtracting 336 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18678.3
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
42 goes into 340 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18678.38
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 18678.38
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 42 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 18678.3809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 18678.38095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 18678.380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 18678.3809523
Subtract 126 from 160 to 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.

Advancing to step 14:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18678.38095238
Subtract 336 from 340 to 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 18678.38095238, with a leftover of 4e-09.
