We divide 393069 by 23
Our goal is to divide 393069 by 23.

Moving on to step 1:
If we divide 3 by 23, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 23

On to step 2:
If we divide 39 by 23, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 23 from 39 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 23

Step 3:
23 can be fit into 163 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 161 from 163, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 23

On to step 4:
20 divided by 23 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 170.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 23

On to step 5:
23 goes into 206 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 1708.0
Subtracting 184 from 206 leaves us with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 23

Step 6:
The number 23 fits into 229 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 17089.0
The remainder is 22 after subtracting 207 from 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 23, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 17089.9
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
130 divided by 23 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17089.95
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
When dividing 150 by 23, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 17089.956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 23, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17089.9565
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.

Let's proceed to step 11:
23 goes into 50 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 17089.95652
If we subtract 46 from 50, 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.

Going ahead to step 12:
If we divide 40 by 23, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 17089.956521
If we take 23 away from 40, we end up 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.

On to step 13:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 17089.9565217
Subtracting 161 from 170 leaves us 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.

Advancing to step 14:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 17089.95652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 17089.95652173 with a remainder of 2.1e-08.
