99157352 ÷ 23 
We're looking to find how many times 23 goes into 99157352.

On to step 1:
The number 23 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 23

On to step 2:
23 can be fit into 99 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 92 from 99, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 23

Let's proceed to step 3:
23 can be fit into 71 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 2 after subtracting 69 from 71.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 23

Going ahead to step 4:
25 divided by 23 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
Subtract 23 from 25 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 23

On to step 5:
If we divide 27 by 23, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 4311.0
Deduct 23 from 27 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 23

Let's proceed to step 6:
43 divided by 23 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 43111.0
Subtract 23 from 43 to get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 23

Going ahead to step 7:
If we divide 205 by 23, we get 8 and a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 431118.0
Subtract 184 from 205 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 23

Let's proceed to step 8:
The number 23 fits into 212 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 4311189.0
Subtracting 207 from 212 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 9:
If we divide 50 by 23, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 4311189.2
Subtracting 46 from 50 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.

On to step 10:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 4311189.21
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.

Let's proceed to step 11:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 4311189.217
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.

On to step 12:
When dividing 90 by 23, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 4311189.2173
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.

Going ahead to step 13:
210 divided by 23 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 4311189.21739
Subtract 207 from 210 to 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.

Step 14:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4311189.217391
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.

Step 15:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 4311189.2173913
If we subtract 69 from 70, we 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.

Let's proceed to step 16:
23 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4311189.2173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4311189.2173913 and a remainder of 1e-08.
