We divide 28993390 by 23
We want to divide 28993390 by 23.

Step 1:
23 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 23

Advancing to step 2:
23 can be fit into 28 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 28, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 23

Moving on to step 3:
23 goes into 59 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 46 away from 59, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 23

Moving on to step 4:
When dividing 139 by 23, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 1 after subtracting 138 from 139.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 23

Let's proceed to step 5:
If we divide 13 by 23, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 1260.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 23

Step 6:
The number 23 fits into 133 5 times, leaving a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 12605.0
Deduct 115 from 133 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 23

On to step 7:
23 goes into 189 8 times with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 126058.0
The remainder is 5 after subtracting 184 from 189.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 23

Going ahead to step 8:
If we divide 50 by 23, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1260582.0
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1260582.1
Deduct 23 from 40 and we're left 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.

Going ahead to step 10:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 1260582.17
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.

Moving on to step 11:
If we divide 90 by 23, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1260582.173
If we subtract 69 from 90, we 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.

Moving on to step 12:
23 goes into 210 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 1260582.1739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1260582.17391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1260582.173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 15:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1260582.173913
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
23 goes into 100 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1260582.17391304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 1260582.17391304, with a leftover of 8e-09.
