We look at the division of 78778919 by 584 
Our goal is to divide 78778919 by 584.

On to step 1:
584 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 584

Moving on to step 2:
The number 584 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 584

Advancing to step 3:
787 divided by 584 is 1 with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 584 from 787 leaves us with 203.
Grab the next digit (7) from the dividend, add it to 203, then carry on: 2037 / 584

Going ahead to step 4:
2037 divided by 584 is 3 with a remainder of 285.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1752 from 2037 leaves us with 285.
Append the next digit (8) from the dividend to 285 and continue with: 2858 / 584

Step 5:
When dividing 2858 by 584, we get 4 with a remainder of 522.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 2336 from 2858 to get 522.
Include the next digit (9) from the dividend after 522, then repeat: 5229 / 584

Moving on to step 6:
If we divide 5229 by 584, we get 8 and a remainder of 557.
Write down 8 as next digit of the result. 
Result so far: 1348.0
Subtract 4672 from 5229 to get 557.
Append the next digit (1) from the dividend to 557 and continue with: 5571 / 584

Moving on to step 7:
584 goes into 5571 9 times with a remainder of 315.
Put 9 as the next digit of the answer. 
Result so far: 13489.0
Deduct 5256 from 5571 and we're left with 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 584

Advancing to step 8:
If we divide 3159 by 584, we get 5 and a remainder of 239.
Use 5 as the next digit of our solution. 
Result so far: 134895.0
If we subtract 2920 from 3159, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 9:
584 can be fit into 2390 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 134895.4
If we take 2336 away from 2390, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
If we divide 540 by 584, we get 0 and a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 134895.4
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
If we divide 5400 by 584, we get 9 and a remainder of 144.
Write down 9 as next digit of the result. 
Result so far: 134895.409
Subtract 5256 from 5400 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
The number 584 fits into 1440 2 times, leaving a remainder of 272.
The next digit of our result is 2. 
Result so far: 134895.4092
The remainder is 272 after subtracting 1168 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 13:
2720 divided by 584 is 4 with a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 134895.40924
Subtract 2336 from 2720 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
584 goes into 3840 6 times with a remainder of 336.
The number 6 becomes the next digit in our result. 
Result so far: 134895.409246
Subtracting 3504 from 3840 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 15:
If we divide 3360 by 584, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 134895.4092465
Subtract 2920 from 3360 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 16:
If we divide 4400 by 584, we get 7 and a remainder of 312.
The number 7 becomes the next digit in our result. 
Result so far: 134895.40924657
If we take 4088 away from 4400, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 134895.40924657 with a remainder of 3.12e-07.
