We look at the division of 78423822 by 684 
We're looking to find how many times 684 goes into 78423822.

On to step 1:
7 divided by 684 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 684

On to step 2:
684 goes into 78 0 times with 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.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 684

On to step 3:
684 can be fit into 784 1 times, resulting in a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 684 from 784, we get 100.
Include the next digit (2) from the dividend after 100, then repeat: 1002 / 684

Step 4:
684 goes into 1002 1 times with a remainder of 318.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 684 from 1002 leaves us with 318.
Take the next digit (3) from the dividend and append it to 318, then repeat: 3183 / 684

On to step 5:
When dividing 3183 by 684, we get 4 with a remainder of 447.
The next digit of our result is 4. 
Result so far: 114.0
Subtract 2736 from 3183 to get 447.
Bring next digit (8) of the dividend behind the 447 and repeat the process: 4478 / 684

Advancing to step 6:
684 goes into 4478 6 times with a remainder of 374.
Use 6 as the next digit of our solution. 
Result so far: 1146.0
The remainder is 374 after subtracting 4104 from 4478.
Take the next digit (2) from the dividend and append it to 374, then repeat: 3742 / 684

Moving on to step 7:
684 goes into 3742 5 times with a remainder of 322.
Write down 5 as next digit of the result. 
Result so far: 11465.0
Deduct 3420 from 3742 and we're left with 322.
Take the next digit (2) from the dividend and append it to 322, then repeat: 3222 / 684

Step 8:
If we divide 3222 by 684, we get 4 and a remainder of 486.
Use 4 as the next digit of our solution. 
Result so far: 114654.0
Subtracting 2736 from 3222 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 9:
The number 684 fits into 4860 7 times, leaving a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 114654.7
If we take 4788 away from 4860, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
684 can be fit into 720 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 114654.71
If we take 684 away from 720, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 684, we get 0 and a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 114654.71
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
If we divide 3600 by 684, we get 5 and a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 114654.7105
The remainder is 180 after subtracting 3420 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
The number 684 fits into 1800 2 times, leaving a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 114654.71052
Deduct 1368 from 1800 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
The number 684 fits into 4320 6 times, leaving a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 114654.710526
Deduct 4104 from 4320 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 15:
The number 684 fits into 2160 3 times, leaving a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 114654.7105263
Subtracting 2052 from 2160 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 16:
1080 divided by 684 is 1 with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 114654.71052631
The remainder is 396 after subtracting 684 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final outcome is 114654.71052631, with a leftover of 3.96e-07.
