45490 ÷ 43 
We want to divide 45490 by 43.

Going ahead to step 1:
43 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 43

On to step 2:
The number 43 fits into 45 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 45 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 43

Moving on to step 3:
The number 43 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 24 leaves us with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 43

Let's proceed to step 4:
43 can be fit into 249 5 times, resulting in a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 215 from 249 to get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 43

Let's proceed to step 5:
340 divided by 43 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.0
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 6:
The number 43 fits into 390 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1057.9
If we subtract 387 from 390, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
43 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1057.9
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 43 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 1057.906
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.

Moving on to step 9:
The number 43 fits into 420 9 times, leaving a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1057.9069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1057.90697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1057.906976
Subtracting 258 from 290 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 43, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1057.9069767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
190 divided by 43 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1057.90697674
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1057.90697674 and a remainder of 1.8e-08.
