Let's divide 645004 by 99
Let's see how many times 99 fits into 645004.

Going ahead to step 1:
6 divided by 99 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 99

Going ahead to step 2:
When dividing 64 by 99, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 99

On to step 3:
When dividing 645 by 99, we get 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 594 away from 645, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 99

On to step 4:
When dividing 510 by 99, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 495 from 510, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 99

Let's proceed to step 5:
150 divided by 99 is 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 651.0
If we subtract 99 from 150, we get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 99

Advancing to step 6:
When dividing 514 by 99, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 6515.0
Deduct 495 from 514 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
99 can be fit into 190 1 times, resulting in a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6515.1
The remainder is 91 after subtracting 99 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 8:
If we divide 910 by 99, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 6515.19
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
99 can be fit into 190 1 times, resulting in a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 6515.191
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 10:
When dividing 910 by 99, we get 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 6515.1919
If we take 891 away from 910, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
190 divided by 99 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 6515.19191
Deduct 99 from 190 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 12:
910 divided by 99 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 6515.191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
190 divided by 99 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 6515.1919191
Subtract 99 from 190 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 14:
The number 99 fits into 910 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 6515.19191919
Subtracting 891 from 910 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 6515.19191919 with a remaining 1.9e-08.
