256859 ÷ 43 
Our goal is to divide 256859 by 43.

Going ahead to step 1:
The number 43 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 43

Let's proceed to step 2:
43 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 43

Going ahead to step 3:
When dividing 256 by 43, we get 5 with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 215 away from 256, we end up with 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 43

Let's proceed to step 4:
43 can be fit into 418 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 387 from 418, we get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 43

Going ahead to step 5:
43 can be fit into 315 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 597.0
If we take 301 away from 315, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 43

Going ahead to step 6:
If we divide 149 by 43, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 5973.0
If we take 129 away from 149, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 43 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 5973.4
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
43 goes into 280 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 5973.46
Subtracting 258 from 280 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.

Going ahead to step 9:
The number 43 fits into 220 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5973.465
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.

Step 10:
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: 5973.4651
If we subtract 43 from 50, we 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.

Let's proceed to step 11:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 5973.46511
Deduct 43 from 70 and we're left with 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 5973.46511, and the remainder is 2.7e-05.
