We divide 550809 by 43
We're looking to find how many times 43 goes into 550809.

Going ahead to step 1:
5 divided by 43 is 0 with 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.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 43

Advancing to step 2:
When dividing 55 by 43, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 55, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 43

On to step 3:
The number 43 fits into 120 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 86 from 120 to get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 43

Advancing to step 4:
43 goes into 348 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we take 344 away from 348, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 43

Going ahead to step 5:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1280.0
If we take 0 away from 40, we end up with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 43

Moving on to step 6:
43 goes into 409 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 12809.0
Subtracting 387 from 409 leaves us with 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 7:
If we divide 220 by 43, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12809.5
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
43 goes into 50 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 12809.51
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.

Advancing to step 9:
70 divided by 43 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 12809.511
If we subtract 43 from 70, we 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 final outcome is 12809.511, with a leftover of 0.0027.
