We look at the division of 721939 by 23 
We want to figure out the number of times 721939 can be divided by 23.

Moving on to step 1:
When dividing 7 by 23, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 23

Step 2:
The number 23 fits into 72 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 69 from 72 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 23

Step 3:
When dividing 31 by 23, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 8 after subtracting 23 from 31.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 23

Going ahead to step 4:
The number 23 fits into 89 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 313.0
If we subtract 69 from 89, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 23

On to step 5:
203 divided by 23 is 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 3138.0
If we take 184 away from 203, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 23

Going ahead to step 6:
23 goes into 199 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 31388.0
If we subtract 184 from 199, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 31388.6
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
23 goes into 120 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 31388.65
Subtracting 115 from 120 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.

On to step 9:
50 divided by 23 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 31388.652
If we take 46 away from 50, we end up 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.
Use 1 as the next digit of our solution. 
Result so far: 31388.6521
Subtracting 23 from 40 leaves us 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.

On to step 11:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 31388.65217
If we subtract 161 from 170, we 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.

Step 12:
23 goes into 90 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 31388.652173
If we take 69 away from 90, we end up 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.

Moving on to step 13:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 31388.6521739
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.

Moving on to step 14:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 31388.65217391
Subtracting 23 from 30 leaves us 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.

In conclusion, the division gives 31388.65217391 with a balance of 7e-09.
