86159468 ÷ 558 
We want to figure out the number of times 86159468 can be divided by 558.

Let's proceed to step 1:
8 divided by 558 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 558

Advancing to step 2:
558 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 558

Step 3:
The number 558 fits into 861 1 times, leaving a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 558 from 861 to get 303.
Grab the next digit (5) from the dividend, add it to 303, then carry on: 3035 / 558

Step 4:
558 goes into 3035 5 times with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2790 from 3035 and we're left with 245.
Fetch the next digit (9) from the dividend, attach it to 245 and continue: 2459 / 558

Advancing to step 5:
558 can be fit into 2459 4 times, resulting in a remainder of 227.
Write down 4 as next digit of the result. 
Result so far: 154.0
Deduct 2232 from 2459 and we're left with 227.
Take the next digit (4) from the dividend and append it to 227, then repeat: 2274 / 558

Going ahead to step 6:
558 can be fit into 2274 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1544.0
Subtracting 2232 from 2274 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 558

Moving on to step 7:
If we divide 426 by 558, we get 0 and a remainder of 426.
The next digit of our result is 0. 
Result so far: 15440.0
The remainder is 426 after subtracting 0 from 426.
Take the next digit (8) from the dividend and append it to 426, then repeat: 4268 / 558

Moving on to step 8:
4268 divided by 558 is 7 with a remainder of 362.
The next digit of our result is 7. 
Result so far: 154407.0
Deduct 3906 from 4268 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 9:
558 goes into 3620 6 times with a remainder of 272.
The next digit of our result is 6. 
Result so far: 154407.6
If we subtract 3348 from 3620, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
If we divide 2720 by 558, we get 4 and a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 154407.64
If we subtract 2232 from 2720, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
When dividing 4880 by 558, we get 8 with a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 154407.648
If we subtract 4464 from 4880, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 12:
4160 divided by 558 is 7 with a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 154407.6487
Deduct 3906 from 4160 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 13:
When dividing 2540 by 558, we get 4 with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 154407.64874
If we subtract 2232 from 2540, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 14:
The number 558 fits into 3080 5 times, leaving a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 154407.648745
If we subtract 2790 from 3080, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 15:
2900 divided by 558 is 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 154407.6487455
Deduct 2790 from 2900 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 154407.6487455, and the remainder is 1.1e-06.
