Let's divide 665173 by 99
We want to figure out the number of times 665173 can be divided by 99.

Step 1:
6 divided by 99 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 99

Step 2:
66 divided by 99 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 99

Step 3:
When dividing 665 by 99, we get 6 with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 594 from 665 leaves us with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 99

Step 4:
The number 99 fits into 711 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 693 from 711, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 99

Moving on to step 5:
99 goes into 187 1 times with a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 671.0
The remainder is 88 after subtracting 99 from 187.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 99

Going ahead to step 6:
883 divided by 99 is 8 with a remainder of 91.
The next digit of our result is 8. 
Result so far: 6718.0
If we subtract 792 from 883, we 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.

Advancing to step 7:
99 can be fit into 910 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6718.9
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 8:
99 can be fit into 190 1 times, resulting in a remainder of 91.
The next digit of our result is 1. 
Result so far: 6718.91
Subtracting 99 from 190 leaves us 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 9:
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: 6718.919
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.

Going ahead to step 10:
190 divided by 99 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6718.9191
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.

Moving on to step 11:
99 can be fit into 910 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 6718.91919
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 12:
190 divided by 99 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6718.919191
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.

Let's proceed to step 13:
If we divide 910 by 99, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 6718.9191919
If we subtract 891 from 910, we get 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 14:
99 goes into 190 1 times with a remainder of 91.
The next digit of our result is 1. 
Result so far: 6718.91919191
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.

Our division results in 6718.91919191 with a remaining 9.1e-08.
