We're dividing 436671 by 23 
Our goal is to divide 436671 by 23.

Advancing to step 1:
23 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 23

Step 2:
If we divide 43 by 23, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 23 from 43 to get 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 23

Going ahead to step 3:
If we divide 206 by 23, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 184 from 206, we get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 23

Advancing to step 4:
23 goes into 226 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 189.0
Subtracting 207 from 226 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 23

Let's proceed to step 5:
23 goes into 197 8 times with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 1898.0
Subtracting 184 from 197 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 23

Step 6:
The number 23 fits into 131 5 times, leaving a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 18985.0
Deduct 115 from 131 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 7:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 18985.6
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.

Moving on to step 8:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 18985.69
Subtract 207 from 220 to 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.

Going ahead to step 9:
When dividing 130 by 23, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 18985.695
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.

Going ahead to step 10:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 18985.6956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
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: 18985.69565
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
50 divided by 23 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 18985.695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 23, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 18985.6956521
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.

Let's proceed to step 14:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 18985.69565217
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.

The final outcome is 18985.69565217, with a leftover of 9e-09.
