519428 ÷ 43 
We want to figure out the number of times 519428 can be divided by 43.

Step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 43

Going ahead to step 2:
43 goes into 51 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 43 away from 51, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 43

Let's proceed to step 3:
89 divided by 43 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 3 after subtracting 86 from 89.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 43

Moving on to step 4:
If we divide 34 by 43, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 120.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 43

Advancing to step 5:
43 can be fit into 342 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 1207.0
The remainder is 41 after subtracting 301 from 342.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 43

Step 6:
418 divided by 43 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 12079.0
If we subtract 387 from 418, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 43, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 12079.7
Subtracting 301 from 310 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 43, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12079.72
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
43 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12079.72
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
43 can be fit into 400 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 12079.7209
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
130 divided by 43 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 12079.72093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
43 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12079.72093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 43, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 12079.7209302
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 43 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 12079.72093023
The remainder is 11 after subtracting 129 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 12079.72093023 with a remaining 1.1e-08.
