We divide 809639 by 23
We want to divide 809639 by 23.

Going ahead to step 1:
23 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 23

Let's proceed to step 2:
23 goes into 80 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 69 from 80, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 23

Moving on to step 3:
The number 23 fits into 119 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 115 from 119, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 23

Let's proceed to step 4:
The number 23 fits into 46 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
Subtract 46 from 46 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 23

On to step 5:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 3520.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 23

Let's proceed to step 6:
The number 23 fits into 39 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 35201.0
If we take 23 away from 39, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 35201.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 35201.69
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 35201.695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 35201.6956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 23 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 35201.69565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 23, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 35201.695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 35201.6956521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
170 divided by 23 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 35201.69565217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 35201.69565217, and the remainder is 9e-09.
