Let's divide 43088078 by 558
Let's see how many times 558 fits into 43088078.

On to step 1:
When dividing 4 by 558, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 558

Moving on to step 2:
The number 558 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 558

Going ahead to step 3:
When dividing 430 by 558, we get 0 with a remainder of 430.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 430, we end up with 430.
Bring next digit (8) of the dividend behind the 430 and repeat the process: 4308 / 558

Advancing to step 4:
The number 558 fits into 4308 7 times, leaving a remainder of 402.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 3906 from 4308 to get 402.
Take the next digit (8) from the dividend and append it to 402, then repeat: 4028 / 558

On to step 5:
The number 558 fits into 4028 7 times, leaving a remainder of 122.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 3906 from 4028, we get 122.
Include the next digit (0) from the dividend after 122, then repeat: 1220 / 558

Advancing to step 6:
558 goes into 1220 2 times with a remainder of 104.
The next digit of our result is 2. 
Result so far: 772.0
If we subtract 1116 from 1220, we get 104.
Grab the next digit (7) from the dividend, add it to 104, then carry on: 1047 / 558

Advancing to step 7:
If we divide 1047 by 558, we get 1 and a remainder of 489.
The next digit of our result is 1. 
Result so far: 7721.0
Subtract 558 from 1047 to get 489.
Grab the next digit (8) from the dividend, add it to 489, then carry on: 4898 / 558

Moving on to step 8:
If we divide 4898 by 558, we get 8 and a remainder of 434.
Write down 8 as next digit of the result. 
Result so far: 77218.0
If we take 4464 away from 4898, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 9:
4340 divided by 558 is 7 with a remainder of 434.
Put 7 as the next digit of the answer. 
Result so far: 77218.7
If we take 3906 away from 4340, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 10:
The number 558 fits into 4340 7 times, leaving a remainder of 434.
Put 7 as the next digit of the answer. 
Result so far: 77218.77
Subtracting 3906 from 4340 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

The final result is 77218.77 with a remainder of 0.434.
