Let's divide 99016857 by 509
We want to figure out the number of times 99016857 can be divided by 509.

Advancing to step 1:
509 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 509

On to step 2:
If we divide 99 by 509, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 509

Going ahead to step 3:
When dividing 990 by 509, we get 1 with a remainder of 481.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 509 from 990 to get 481.
Grab the next digit (1) from the dividend, add it to 481, then carry on: 4811 / 509

Let's proceed to step 4:
509 goes into 4811 9 times with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 4581 from 4811, we get 230.
Include the next digit (6) from the dividend after 230, then repeat: 2306 / 509

Moving on to step 5:
509 goes into 2306 4 times with a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
The remainder is 270 after subtracting 2036 from 2306.
Grab the next digit (8) from the dividend, add it to 270, then carry on: 2708 / 509

Let's proceed to step 6:
2708 divided by 509 is 5 with a remainder of 163.
Put 5 as the next digit of the answer. 
Result so far: 1945.0
If we take 2545 away from 2708, we end up with 163.
Fetch the next digit (5) from the dividend, attach it to 163 and continue: 1635 / 509

On to step 7:
When dividing 1635 by 509, we get 3 with a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 19453.0
The remainder is 108 after subtracting 1527 from 1635.
Append the next digit (7) from the dividend to 108 and continue with: 1087 / 509

Advancing to step 8:
When dividing 1087 by 509, we get 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 194532.0
If we take 1018 away from 1087, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
509 goes into 690 1 times with a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 194532.1
Subtract 509 from 690 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 10:
When dividing 1810 by 509, we get 3 with a remainder of 283.
Put 3 as the next digit of the answer. 
Result so far: 194532.13
If we take 1527 away from 1810, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 11:
The number 509 fits into 2830 5 times, leaving a remainder of 285.
The next digit of our result is 5. 
Result so far: 194532.135
If we take 2545 away from 2830, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 12:
When dividing 2850 by 509, we get 5 with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 194532.1355
Deduct 2545 from 2850 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

In conclusion, the division gives 194532.1355 with a balance of 0.00305.
