We're dividing 28089359 by 23 
We're looking to find how many times 23 goes into 28089359.

Advancing to step 1:
When dividing 2 by 23, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 23

Step 2:
The number 23 fits into 28 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 23 from 28 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 23

Let's proceed to step 3:
If we divide 50 by 23, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 46 from 50 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 23

On to step 4:
23 goes into 48 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 46 away from 48, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 23

Step 5:
If we divide 29 by 23, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1221.0
Subtracting 23 from 29 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 23

Let's proceed to step 6:
23 goes into 63 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 12212.0
If we take 46 away from 63, we end up with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 23

Step 7:
23 goes into 175 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 122127.0
The remainder is 14 after subtracting 161 from 175.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 23

Going ahead to step 8:
When dividing 149 by 23, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 1221276.0
Subtract 138 from 149 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
When dividing 110 by 23, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1221276.4
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
If we divide 180 by 23, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1221276.47
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1221276.478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 1221276.4782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 1221276.47826
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
23 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1221276.47826
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 1221276.4782608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
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: 1221276.47826086
If we take 138 away from 160, we end up 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.

Our division results in 1221276.47826086 with a remaining 2.2e-08.
