Let's divide 345043 by 23
We're looking to find how many times 23 goes into 345043.

On to step 1:
23 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 23

On to step 2:
23 can be fit into 34 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 23 from 34, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 23

Going ahead to step 3:
When dividing 115 by 23, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 115 from 115 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 23

Advancing to step 4:
0 divided by 23 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we subtract 0 from 0, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 23

On to step 5:
23 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 1500.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 23

Step 6:
23 can be fit into 43 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 15001.0
Deduct 23 from 43 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 15001.8
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
If we divide 160 by 23, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 15001.86
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
23 goes into 220 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 15001.869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
If we divide 130 by 23, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 15001.8695
If we take 115 away from 130, we end up 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.

Going ahead to step 11:
23 goes into 150 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 15001.86956
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 12:
120 divided by 23 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 15001.869565
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.

Going ahead to step 13:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 15001.8695652
Subtracting 46 from 50 leaves us 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.

Going ahead to step 14:
23 goes into 40 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 15001.86956521
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.

Our division results in 15001.86956521 with a remaining 1.7e-08.
