We look at the division of 81566810 by 558 
We want to figure out the number of times 81566810 can be divided by 558.

Moving on to step 1:
8 divided by 558 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 558

Let's proceed to step 2:
558 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 558

On to step 3:
If we divide 815 by 558, we get 1 and a remainder of 257.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 257 after subtracting 558 from 815.
Take the next digit (6) from the dividend and append it to 257, then repeat: 2576 / 558

Let's proceed to step 4:
558 can be fit into 2576 4 times, resulting in a remainder of 344.
The next digit of our result is 4. 
Result so far: 14.0
If we take 2232 away from 2576, we end up with 344.
Bring next digit (6) of the dividend behind the 344 and repeat the process: 3446 / 558

Going ahead to step 5:
When dividing 3446 by 558, we get 6 with a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Subtracting 3348 from 3446 leaves us with 98.
Take the next digit (8) from the dividend and append it to 98, then repeat: 988 / 558

Let's proceed to step 6:
The number 558 fits into 988 1 times, leaving a remainder of 430.
Write down 1 as next digit of the result. 
Result so far: 1461.0
Deduct 558 from 988 and we're left with 430.
Take the next digit (1) from the dividend and append it to 430, then repeat: 4301 / 558

Let's proceed to step 7:
If we divide 4301 by 558, we get 7 and a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 14617.0
Deduct 3906 from 4301 and we're left with 395.
Take the next digit (0) from the dividend and append it to 395, then repeat: 3950 / 558

Going ahead to step 8:
558 can be fit into 3950 7 times, resulting in a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 146177.0
If we subtract 3906 from 3950, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
558 goes into 440 0 times with a remainder of 440.
The next digit of our result is 0. 
Result so far: 146177.0
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
If we divide 4400 by 558, we get 7 and a remainder of 494.
Write down 7 as next digit of the result. 
Result so far: 146177.07
The remainder is 494 after subtracting 3906 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 11:
558 can be fit into 4940 8 times, resulting in a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 146177.078
Subtracting 4464 from 4940 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 12:
558 can be fit into 4760 8 times, resulting in a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 146177.0788
If we take 4464 away from 4760, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 146177.0788, with a leftover of 0.00296.
