We're dividing 170301 by 23 
We want to figure out the number of times 170301 can be divided by 23.

Moving on to step 1:
The number 23 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 23

Moving on to step 2:
When dividing 17 by 23, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 23

On to step 3:
When dividing 170 by 23, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 9 after subtracting 161 from 170.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 23

Let's proceed to step 4:
The number 23 fits into 93 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 92 away from 93, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 23

Going ahead to step 5:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 740.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 23

Step 6:
23 goes into 101 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 7404.0
Subtract 92 from 101 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 7:
When dividing 90 by 23, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 7404.3
Subtracting 69 from 90 leaves us with 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 8:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 7404.39
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.

Going ahead to step 9:
If we divide 30 by 23, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 7404.391
If we take 23 away from 30, we end up 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.

On to step 10:
When dividing 70 by 23, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 7404.3913
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.

Moving on to step 11:
When dividing 10 by 23, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7404.3913
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.

Step 12:
If we divide 100 by 23, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7404.391304
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.

Step 13:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 7404.3913043
Deduct 69 from 80 and we're left 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.

Let's proceed to step 14:
The number 23 fits into 110 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 7404.39130434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 7404.39130434 with a remainder of 1.8e-08.
