Let's divide 43428686 by 558
Our goal is to divide 43428686 by 558.

On to step 1:
4 divided by 558 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 558

On to step 2:
558 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 558

On to step 3:
434 divided by 558 is 0 with a remainder of 434.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 434 and we're left with 434.
Fetch the next digit (2) from the dividend, attach it to 434 and continue: 4342 / 558

Going ahead to step 4:
4342 divided by 558 is 7 with a remainder of 436.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 3906 from 4342 to get 436.
Append the next digit (8) from the dividend to 436 and continue with: 4368 / 558

On to step 5:
If we divide 4368 by 558, we get 7 and a remainder of 462.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 3906 away from 4368, we end up with 462.
Include the next digit (6) from the dividend after 462, then repeat: 4626 / 558

Moving on to step 6:
558 can be fit into 4626 8 times, resulting in a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 778.0
If we subtract 4464 from 4626, we get 162.
Grab the next digit (8) from the dividend, add it to 162, then carry on: 1628 / 558

Going ahead to step 7:
1628 divided by 558 is 2 with a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 7782.0
Deduct 1116 from 1628 and we're left with 512.
Bring next digit (6) of the dividend behind the 512 and repeat the process: 5126 / 558

Let's proceed to step 8:
When dividing 5126 by 558, we get 9 with a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 77829.0
If we subtract 5022 from 5126, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 9:
558 goes into 1040 1 times with a remainder of 482.
Record the quotient 1 as the next digit in the result. 
Result so far: 77829.1
Deduct 558 from 1040 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 10:
558 goes into 4820 8 times with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 77829.18
Subtract 4464 from 4820 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
558 goes into 3560 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 77829.186
The remainder is 212 after subtracting 3348 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 12:
2120 divided by 558 is 3 with a remainder of 446.
The next digit of our result is 3. 
Result so far: 77829.1863
The remainder is 446 after subtracting 1674 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 13:
558 can be fit into 4460 7 times, resulting in a remainder of 554.
Put 7 as the next digit of the answer. 
Result so far: 77829.18637
Subtracting 3906 from 4460 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 14:
558 goes into 5540 9 times with a remainder of 518.
The number 9 becomes the next digit in our result. 
Result so far: 77829.186379
If we take 5022 away from 5540, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 15:
When dividing 5180 by 558, we get 9 with a remainder of 158.
Use 9 as the next digit of our solution. 
Result so far: 77829.1863799
If we subtract 5022 from 5180, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final outcome is 77829.1863799, with a leftover of 1.58e-06.
