Let's divide 80765423 by 558
We want to figure out the number of times 80765423 can be divided by 558.

Going ahead to step 1:
558 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 558

On to step 2:
When dividing 80 by 558, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 558

Going ahead to step 3:
807 divided by 558 is 1 with a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 558 from 807 to get 249.
Bring next digit (6) of the dividend behind the 249 and repeat the process: 2496 / 558

On to step 4:
If we divide 2496 by 558, we get 4 and a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 264 after subtracting 2232 from 2496.
Include the next digit (5) from the dividend after 264, then repeat: 2645 / 558

Going ahead to step 5:
If we divide 2645 by 558, we get 4 and a remainder of 413.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtract 2232 from 2645 to get 413.
Fetch the next digit (4) from the dividend, attach it to 413 and continue: 4134 / 558

Going ahead to step 6:
The number 558 fits into 4134 7 times, leaving a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 1447.0
The remainder is 228 after subtracting 3906 from 4134.
Append the next digit (2) from the dividend to 228 and continue with: 2282 / 558

Step 7:
558 goes into 2282 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 14474.0
If we take 2232 away from 2282, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 558

Going ahead to step 8:
558 goes into 503 0 times with a remainder of 503.
The number 0 becomes the next digit in our result. 
Result so far: 144740.0
Subtract 0 from 503 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Going ahead to step 9:
If we divide 5030 by 558, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 144740.9
If we take 5022 away from 5030, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
558 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 144740.9
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
558 goes into 800 1 times with a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 144740.901
If we take 558 away from 800, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
558 goes into 2420 4 times with a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 144740.9014
If we subtract 2232 from 2420, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 13:
1880 divided by 558 is 3 with a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 144740.90143
The remainder is 206 after subtracting 1674 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 14:
The number 558 fits into 2060 3 times, leaving a remainder of 386.
Write down 3 as next digit of the result. 
Result so far: 144740.901433
If we take 1674 away from 2060, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

After the division, we end up with 144740.901433 and a remainder of 3.86e-05.
