437212 divided by 23 
Let's see how many times 23 fits into 437212.

Step 1:
23 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 23

Let's proceed to step 2:
23 can be fit into 43 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 43, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 23

Going ahead to step 3:
207 divided by 23 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 207 from 207, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 23

Let's proceed to step 4:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Going ahead to step 5:
23 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 1900.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 23

On to step 6:
212 divided by 23 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 19009.0
Deduct 207 from 212 and we're left 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 7:
If we divide 50 by 23, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 19009.2
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.

Step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 19009.21
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.

Moving on to step 9:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 19009.217
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.

Let's proceed to step 10:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 19009.2173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
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: 19009.21739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 19009.217391
If we subtract 23 from 30, we get 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 13:
If we divide 70 by 23, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 19009.2173913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
23 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19009.2173913
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.

The final outcome is 19009.2173913, with a leftover of 1e-08.
