We're dividing 78842409 by 584 
We want to figure out the number of times 78842409 can be divided by 584.

Advancing to step 1:
584 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 584

Advancing to step 2:
584 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 584

On to step 3:
The number 584 fits into 788 1 times, leaving a remainder of 204.
The next digit of our result is 1. 
Result so far: 1.0
If we take 584 away from 788, we end up with 204.
Grab the next digit (4) from the dividend, add it to 204, then carry on: 2044 / 584

On to step 4:
When dividing 2044 by 584, we get 3 with a remainder of 292.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1752 from 2044 to get 292.
Bring next digit (2) of the dividend behind the 292 and repeat the process: 2922 / 584

On to step 5:
When dividing 2922 by 584, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
If we take 2920 away from 2922, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 584

Moving on to step 6:
The number 584 fits into 24 0 times, leaving a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 1350.0
If we subtract 0 from 24, we get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 584

Let's proceed to step 7:
584 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 13500.0
If we take 0 away from 240, we end up with 240.
Include the next digit (9) from the dividend after 240, then repeat: 2409 / 584

Going ahead to step 8:
584 can be fit into 2409 4 times, resulting in a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 135004.0
Subtract 2336 from 2409 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
If we divide 730 by 584, we get 1 and a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 135004.1
Subtract 584 from 730 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
1460 divided by 584 is 2 with a remainder of 292.
Record the quotient 2 as the next digit in the result. 
Result so far: 135004.12
The remainder is 292 after subtracting 1168 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 11:
If we divide 2920 by 584, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 135004.125
Subtract 2920 from 2920 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.

Moving on to step 12:
584 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 135004.125
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.

Advancing to step 13:
0 divided by 584 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 135004.125
The remainder is 0 after subtracting 0 from 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 135004.125, with a leftover of 0.0.
