587931 ÷ 43 
We want to divide 587931 by 43.

On to step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 43

Moving on to step 2:
When dividing 58 by 43, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 58, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 43

On to step 3:
The number 43 fits into 157 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 28 after subtracting 129 from 157.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 43

Moving on to step 4:
If we divide 289 by 43, we get 6 and a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 136.0
The remainder is 31 after subtracting 258 from 289.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 43

Step 5:
313 divided by 43 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 1367.0
If we subtract 301 from 313, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 43

Step 6:
When dividing 121 by 43, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 13672.0
If we subtract 86 from 121, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 43 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13672.8
Subtracting 344 from 350 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
43 can be fit into 60 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 13672.81
Subtracting 43 from 60 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.

Advancing to step 9:
The number 43 fits into 170 3 times, leaving a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 13672.813
If we take 129 away from 170, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
The number 43 fits into 410 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 13672.8139
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13672.81395
Subtracting 215 from 230 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
43 goes into 150 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 13672.813953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
210 divided by 43 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 13672.8139534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
The number 43 fits into 380 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 13672.81395348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 13672.81395348, with a leftover of 3.6e-08.
