4050490 ÷ 558 
Let's see how many times 558 fits into 4050490.

Let's proceed to step 1:
The number 558 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 558

Moving on to step 2:
40 divided by 558 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 558

Advancing to step 3:
558 can be fit into 405 0 times, resulting in a remainder of 405.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 405, we end up with 405.
Fetch the next digit (0) from the dividend, attach it to 405 and continue: 4050 / 558

Going ahead to step 4:
The number 558 fits into 4050 7 times, leaving a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 3906 from 4050 to get 144.
Bring next digit (4) of the dividend behind the 144 and repeat the process: 1444 / 558

Going ahead to step 5:
When dividing 1444 by 558, we get 2 with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 1116 from 1444 to get 328.
Append the next digit (9) from the dividend to 328 and continue with: 3289 / 558

Moving on to step 6:
The number 558 fits into 3289 5 times, leaving a remainder of 499.
Use 5 as the next digit of our solution. 
Result so far: 725.0
The remainder is 499 after subtracting 2790 from 3289.
Fetch the next digit (0) from the dividend, attach it to 499 and continue: 4990 / 558

On to step 7:
558 goes into 4990 8 times with a remainder of 526.
The number 8 becomes the next digit in our result. 
Result so far: 7258.0
If we subtract 4464 from 4990, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 8:
When dividing 5260 by 558, we get 9 with a remainder of 238.
Put 9 as the next digit of the answer. 
Result so far: 7258.9
Deduct 5022 from 5260 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
558 can be fit into 2380 4 times, resulting in a remainder of 148.
The next digit of our result is 4. 
Result so far: 7258.94
The remainder is 148 after subtracting 2232 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
The number 558 fits into 1480 2 times, leaving a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 7258.942
Subtracting 1116 from 1480 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
The number 558 fits into 3640 6 times, leaving a remainder of 292.
Put 6 as the next digit of the answer. 
Result so far: 7258.9426
If we subtract 3348 from 3640, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 12:
The number 558 fits into 2920 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 7258.94265
Deduct 2790 from 2920 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 13:
The number 558 fits into 1300 2 times, leaving a remainder of 184.
The next digit of our result is 2. 
Result so far: 7258.942652
Subtract 1116 from 1300 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 14:
558 can be fit into 1840 3 times, resulting in a remainder of 166.
The next digit of our result is 3. 
Result so far: 7258.9426523
Deduct 1674 from 1840 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 15:
The number 558 fits into 1660 2 times, leaving a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 7258.94265232
If we subtract 1116 from 1660, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Our division results in 7258.94265232 with a remaining 5.44e-07.
