We look at the division of 43388239 by 23 
We want to divide 43388239 by 23.

Advancing to step 1:
4 divided by 23 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 23

Moving on to step 2:
If we divide 43 by 23, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 20 after subtracting 23 from 43.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 23

Step 3:
When dividing 203 by 23, we get 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 184 away from 203, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 23

Let's proceed to step 4:
23 goes into 198 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 188.0
Deduct 184 from 198 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 23

On to step 5:
If we divide 148 by 23, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1886.0
If we take 138 away from 148, we end up with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 23

Going ahead to step 6:
When dividing 102 by 23, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 18864.0
Subtracting 92 from 102 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 23

On to step 7:
When dividing 103 by 23, we get 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 188644.0
Subtract 92 from 103 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 23

Moving on to step 8:
If we divide 119 by 23, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 1886445.0
If we subtract 115 from 119, we 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.

Advancing to step 9:
When dividing 40 by 23, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1886445.1
If we subtract 23 from 40, we get 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 10:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1886445.17
Deduct 161 from 170 and we're left 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.

Step 11:
23 goes into 90 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 1886445.173
If we subtract 69 from 90, we 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.

Advancing to step 12:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1886445.1739
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.

Moving on to step 13:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1886445.17391
Subtract 23 from 30 to 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.

On to step 14:
When dividing 70 by 23, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1886445.173913
Subtracting 69 from 70 leaves us 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 15:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1886445.173913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
If we divide 100 by 23, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1886445.17391304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 1886445.17391304, with a leftover of 8e-09.
