78770581 divided by 823 
We want to figure out the number of times 78770581 can be divided by 823.

Going ahead to step 1:
When dividing 7 by 823, we get 0 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 823

Moving on to step 2:
823 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 823

Step 3:
If we divide 787 by 823, we get 0 and a remainder of 787.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 787 leaves us with 787.
Include the next digit (7) from the dividend after 787, then repeat: 7877 / 823

Advancing to step 4:
If we divide 7877 by 823, we get 9 and a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 7407 from 7877 and we're left with 470.
Grab the next digit (0) from the dividend, add it to 470, then carry on: 4700 / 823

Advancing to step 5:
823 goes into 4700 5 times with a remainder of 585.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 585 after subtracting 4115 from 4700.
Include the next digit (5) from the dividend after 585, then repeat: 5855 / 823

On to step 6:
5855 divided by 823 is 7 with a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 957.0
If we take 5761 away from 5855, we end up with 94.
Grab the next digit (8) from the dividend, add it to 94, then carry on: 948 / 823

Moving on to step 7:
948 divided by 823 is 1 with a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 9571.0
Deduct 823 from 948 and we're left with 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 823

On to step 8:
823 goes into 1251 1 times with a remainder of 428.
Use 1 as the next digit of our solution. 
Result so far: 95711.0
The remainder is 428 after subtracting 823 from 1251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 9:
823 goes into 4280 5 times with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 95711.5
Subtracting 4115 from 4280 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
823 goes into 1650 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 95711.52
If we subtract 1646 from 1650, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 823 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 95711.52
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
400 divided by 823 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 95711.52
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 95711.52, with a leftover of 0.004.
