579948 ÷ 43 
We want to divide 579948 by 43.

Step 1:
43 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 43

Step 2:
43 can be fit into 57 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 43 from 57 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 43

Moving on to step 3:
43 can be fit into 149 3 times, resulting in a remainder of 20.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 20 after subtracting 129 from 149.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 43

Going ahead to step 4:
The number 43 fits into 209 4 times, leaving a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we subtract 172 from 209, we get 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 43

On to step 5:
43 can be fit into 374 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 1348.0
Deduct 344 from 374 and we're left with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 43

Step 6:
The number 43 fits into 308 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 13487.0
Subtracting 301 from 308 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 43, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 13487.1
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.

On to step 8:
270 divided by 43 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 13487.16
If we take 258 away from 270, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 43 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 13487.162
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
43 goes into 340 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 13487.1627
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 11:
When dividing 390 by 43, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 13487.16279
The remainder is 3 after subtracting 387 from 390.
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 12:
43 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13487.16279
The remainder is 30 after subtracting 0 from 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 13:
When dividing 300 by 43, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 13487.1627906
If we subtract 258 from 300, we get 42.
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 14:
When dividing 420 by 43, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 13487.16279069
If we take 387 away from 420, we end up 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.

The final outcome is 13487.16279069, with a leftover of 3.3e-08.
