78918085 ÷ 723 
We want to divide 78918085 by 723.

Advancing to step 1:
7 divided by 723 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 723

Step 2:
723 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 723

Let's proceed to step 3:
789 divided by 723 is 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 723 from 789 leaves us with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 723

On to step 4:
If we divide 661 by 723, we get 0 and a remainder of 661.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 661, we end up with 661.
Append the next digit (8) from the dividend to 661 and continue with: 6618 / 723

Advancing to step 5:
723 goes into 6618 9 times with a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 6507 from 6618 and we're left with 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 723

Step 6:
1110 divided by 723 is 1 with a remainder of 387.
Put 1 as the next digit of the answer. 
Result so far: 1091.0
The remainder is 387 after subtracting 723 from 1110.
Include the next digit (8) from the dividend after 387, then repeat: 3878 / 723

Advancing to step 7:
When dividing 3878 by 723, we get 5 with a remainder of 263.
Record the quotient 5 as the next digit in the result. 
Result so far: 10915.0
If we take 3615 away from 3878, we end up with 263.
Include the next digit (5) from the dividend after 263, then repeat: 2635 / 723

Moving on to step 8:
If we divide 2635 by 723, we get 3 and a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 109153.0
Subtracting 2169 from 2635 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 9:
When dividing 4660 by 723, we get 6 with a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 109153.6
Subtracting 4338 from 4660 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 10:
If we divide 3220 by 723, we get 4 and a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 109153.64
Subtracting 2892 from 3220 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 11:
The number 723 fits into 3280 4 times, leaving a remainder of 388.
The next digit of our result is 4. 
Result so far: 109153.644
The remainder is 388 after subtracting 2892 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The quotient of the division is 109153.644, and the remainder is 0.0388.
