We're dividing 537109 by 23 
Let's see how many times 23 fits into 537109.

Let's proceed to step 1:
The number 23 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 23

On to step 2:
23 goes into 53 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 46 from 53 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 23

On to step 3:
The number 23 fits into 77 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 69 from 77, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 23

Let's proceed to step 4:
23 goes into 81 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 233.0
Deduct 69 from 81 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 23

Let's proceed to step 5:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2335.0
Deduct 115 from 120 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 23

Moving on to step 6:
23 can be fit into 59 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 23352.0
Subtracting 46 from 59 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 23, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 23352.5
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 23352.56
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 23, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23352.565
If we take 115 away from 120, we end up 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.

Advancing to step 10:
When dividing 50 by 23, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 23352.5652
Subtract 46 from 50 to get 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 11:
40 divided by 23 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 23352.56521
If we take 23 away from 40, we end up 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.

Going ahead to step 12:
170 divided by 23 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 23352.565217
Subtracting 161 from 170 leaves us 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.

On to step 13:
When dividing 90 by 23, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 23352.5652173
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.

On to step 14:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 23352.56521739
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.

The final outcome is 23352.56521739, with a leftover of 3e-09.
