We look at the division of 789789 by 23 
Let's see how many times 23 fits into 789789.

Let's proceed to step 1:
23 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 23

Let's proceed to step 2:
If we divide 78 by 23, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 69 away from 78, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 23

Moving on to step 3:
23 can be fit into 99 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 92 from 99 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 23

Let's proceed to step 4:
The number 23 fits into 77 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Subtracting 69 from 77 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 23

Advancing to step 5:
When dividing 88 by 23, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3433.0
If we take 69 away from 88, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 23

Let's proceed to step 6:
When dividing 199 by 23, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 34338.0
If we take 184 away from 199, we end up 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.

Let's proceed to step 7:
If we divide 150 by 23, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 34338.6
Subtracting 138 from 150 leaves us 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 8:
If we divide 120 by 23, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 34338.65
The remainder is 5 after subtracting 115 from 120.
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 9:
23 can be fit into 50 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 34338.652
Subtract 46 from 50 to 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 10:
40 divided by 23 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 34338.6521
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
170 divided by 23 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 34338.65217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
23 goes into 90 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 34338.652173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 34338.6521739
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 34338.65217391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 34338.65217391, with a leftover of 7e-09.
