Let's divide 78640543 by 816
We want to divide 78640543 by 816.

Moving on to step 1:
The number 816 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 816

Advancing to step 2:
816 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 816

Moving on to step 3:
The number 816 fits into 786 0 times, leaving a remainder of 786.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 786 to get 786.
Take the next digit (4) from the dividend and append it to 786, then repeat: 7864 / 816

Advancing to step 4:
816 goes into 7864 9 times with a remainder of 520.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7344 from 7864 and we're left with 520.
Grab the next digit (0) from the dividend, add it to 520, then carry on: 5200 / 816

Let's proceed to step 5:
816 goes into 5200 6 times with a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 4896 from 5200, we get 304.
Append the next digit (5) from the dividend to 304 and continue with: 3045 / 816

Moving on to step 6:
3045 divided by 816 is 3 with a remainder of 597.
Use 3 as the next digit of our solution. 
Result so far: 963.0
Deduct 2448 from 3045 and we're left with 597.
Bring next digit (4) of the dividend behind the 597 and repeat the process: 5974 / 816

Let's proceed to step 7:
816 goes into 5974 7 times with a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 9637.0
Subtract 5712 from 5974 to get 262.
Append the next digit (3) from the dividend to 262 and continue with: 2623 / 816

Step 8:
816 goes into 2623 3 times with a remainder of 175.
The next digit of our result is 3. 
Result so far: 96373.0
If we take 2448 away from 2623, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 9:
1750 divided by 816 is 2 with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 96373.2
If we subtract 1632 from 1750, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 10:
When dividing 1180 by 816, we get 1 with a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 96373.21
If we subtract 816 from 1180, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
816 goes into 3640 4 times with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 96373.214
Deduct 3264 from 3640 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 12:
3760 divided by 816 is 4 with a remainder of 496.
Use 4 as the next digit of our solution. 
Result so far: 96373.2144
Subtract 3264 from 3760 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

In conclusion, the division gives 96373.2144 with a balance of 0.00496.
