We're dividing 90808 by 23 
We want to figure out the number of times 90808 can be divided by 23.

Advancing to step 1:
If we divide 9 by 23, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 23

Moving on to step 2:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 69 from 90 to get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 23

Moving on to step 3:
When dividing 218 by 23, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 207 from 218 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 23

Moving on to step 4:
If we divide 110 by 23, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Subtracting 92 from 110 leaves us with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 23

Moving on to step 5:
23 can be fit into 188 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 3948.0
Subtracting 184 from 188 leaves us 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.

Advancing to step 6:
If we divide 40 by 23, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3948.1
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.

Moving on to step 7:
23 goes into 170 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3948.17
Deduct 161 from 170 and we're left 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 8:
23 goes into 90 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3948.173
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.

Step 9:
If we divide 210 by 23, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 3948.1739
Deduct 207 from 210 and we're left 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.

Going ahead to step 10:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3948.17391
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.

Going ahead to step 11:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3948.173913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 3948.173913
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.

Advancing to step 13:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3948.17391304
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 3948.17391304 and a remainder of 8e-09.
