We divide 720645 by 23
Our goal is to divide 720645 by 23.

Advancing to step 1:
When dividing 7 by 23, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 23

Step 2:
23 can be fit into 72 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 69 from 72, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 23

Step 3:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 23 from 30 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 23

Step 4:
The number 23 fits into 76 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Deduct 69 from 76 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 23

On to step 5:
The number 23 fits into 74 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 3133.0
If we take 69 away from 74, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 23

Let's proceed to step 6:
If we divide 55 by 23, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 31332.0
Deduct 46 from 55 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.

Let's proceed to step 7:
23 goes into 90 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 31332.3
Deduct 69 from 90 and we're left 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.

Let's proceed to step 8:
23 goes into 210 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 31332.39
Subtracting 207 from 210 leaves us 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 9:
If we divide 30 by 23, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 31332.391
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.

Going ahead to step 10:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 31332.3913
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.

Advancing to step 11:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 31332.3913
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.

Moving on to step 12:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31332.391304
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.

Going ahead to step 13:
When dividing 80 by 23, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 31332.3913043
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.

Step 14:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 31332.39130434
Subtract 92 from 110 to 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.

After the division, we end up with 31332.39130434 and a remainder of 1.8e-08.
