163988 ÷ 23 
We want to figure out the number of times 163988 can be divided by 23.

Moving on to step 1:
1 divided by 23 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 23

Advancing to step 2:
16 divided by 23 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 23

Going ahead to step 3:
23 goes into 163 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 161 from 163 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 23

Going ahead to step 4:
If we divide 29 by 23, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtract 23 from 29 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 23

On to step 5:
When dividing 68 by 23, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 712.0
If we take 46 away from 68, we end up with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 23

Moving on to step 6:
23 can be fit into 228 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 7129.0
Subtract 207 from 228 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.

Advancing to step 7:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 7129.9
If we take 207 away from 210, we end up 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.

Moving on to step 8:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 7129.91
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.

Let's proceed to step 9:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 7129.913
Subtracting 69 from 70 leaves us 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.

Step 10:
When dividing 10 by 23, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7129.913
If we take 0 away from 10, we end up 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 11:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7129.91304
Subtract 92 from 100 to 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.

Let's proceed to step 12:
23 can be fit into 80 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 7129.913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 7129.9130434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7129.91304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 7129.91304347 with a remaining 1.9e-08.
