We look at the division of 523989 by 43 
Our goal is to divide 523989 by 43.

Going ahead to step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 43

Let's proceed to step 2:
If we divide 52 by 43, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 9 after subtracting 43 from 52.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 43

Let's proceed to step 3:
If we divide 93 by 43, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 86 from 93, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 43

Advancing to step 4:
79 divided by 43 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 43 from 79 and we're left with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 43

On to step 5:
43 goes into 368 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1218.0
If we subtract 344 from 368, we get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 43

Advancing to step 6:
43 can be fit into 249 5 times, resulting in a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 12185.0
If we subtract 215 from 249, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
The number 43 fits into 340 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 12185.7
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
The number 43 fits into 390 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 12185.79
If we subtract 387 from 390, we 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.

Let's proceed to step 9:
If we divide 30 by 43, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12185.79
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 43, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 12185.7906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 43 is 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 12185.79069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
If we divide 330 by 43, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 12185.790697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
43 can be fit into 290 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 12185.7906976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
If we divide 320 by 43, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 12185.79069767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 12185.79069767 with a remainder of 1.9e-08.
