We look at the division of 508159 by 43 
We're looking to find how many times 43 goes into 508159.

Moving on to step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 43

Going ahead to step 2:
The number 43 fits into 50 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 43 from 50 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 43

Let's proceed to step 3:
43 can be fit into 78 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 43 away from 78, we end up with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 43

On to step 4:
351 divided by 43 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 344 from 351 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 43

Advancing to step 5:
When dividing 75 by 43, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1181.0
Subtracting 43 from 75 leaves us with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 43

Let's proceed to step 6:
If we divide 329 by 43, we get 7 and a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 11817.0
Subtracting 301 from 329 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 43 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 11817.6
If we subtract 258 from 280, 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.

On to step 8:
43 goes into 220 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 11817.65
Subtracting 215 from 220 leaves us 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 9:
50 divided by 43 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 11817.651
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
70 divided by 43 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 11817.6511
Subtract 43 from 70 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 11817.6511, and the remainder is 0.00027.
