Let's divide 99876086 by 566
We want to figure out the number of times 99876086 can be divided by 566.

Step 1:
If we divide 9 by 566, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 566

Going ahead to step 2:
99 divided by 566 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 566

Let's proceed to step 3:
566 can be fit into 998 1 times, resulting in a remainder of 432.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 432 after subtracting 566 from 998.
Bring next digit (7) of the dividend behind the 432 and repeat the process: 4327 / 566

Moving on to step 4:
566 can be fit into 4327 7 times, resulting in a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3962 from 4327 and we're left with 365.
Take the next digit (6) from the dividend and append it to 365, then repeat: 3656 / 566

Moving on to step 5:
If we divide 3656 by 566, we get 6 and a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
If we subtract 3396 from 3656, we get 260.
Append the next digit (0) from the dividend to 260 and continue with: 2600 / 566

Moving on to step 6:
566 can be fit into 2600 4 times, resulting in a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 1764.0
Subtract 2264 from 2600 to get 336.
Append the next digit (8) from the dividend to 336 and continue with: 3368 / 566

Going ahead to step 7:
The number 566 fits into 3368 5 times, leaving a remainder of 538.
The next digit of our result is 5. 
Result so far: 17645.0
If we subtract 2830 from 3368, we get 538.
Take the next digit (6) from the dividend and append it to 538, then repeat: 5386 / 566

Advancing to step 8:
566 goes into 5386 9 times with a remainder of 292.
The next digit of our result is 9. 
Result so far: 176459.0
Subtract 5094 from 5386 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 9:
If we divide 2920 by 566, we get 5 and a remainder of 90.
The next digit of our result is 5. 
Result so far: 176459.5
The remainder is 90 after subtracting 2830 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
566 can be fit into 900 1 times, resulting in a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 176459.51
The remainder is 334 after subtracting 566 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 11:
3340 divided by 566 is 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 176459.515
If we take 2830 away from 3340, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 12:
When dividing 5100 by 566, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 176459.5159
Subtract 5094 from 5100 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
566 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 176459.5159
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
566 goes into 600 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 176459.515901
Deduct 566 from 600 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 15:
340 divided by 566 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 176459.515901
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 16:
566 can be fit into 3400 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 176459.51590106
If we subtract 3396 from 3400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 176459.51590106 with a balance of 4e-09.
