We look at the division of 489166 by 99 
Let's see how many times 99 fits into 489166.

On to step 1:
If we divide 4 by 99, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 99

Moving on to step 2:
48 divided by 99 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 99

Going ahead to step 3:
The number 99 fits into 489 4 times, leaving a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 396 from 489 to get 93.
Grab the next digit (1) from the dividend, add it to 93, then carry on: 931 / 99

Going ahead to step 4:
931 divided by 99 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 891 from 931, we get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 99

Moving on to step 5:
99 goes into 406 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we take 396 away from 406, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 99

Let's proceed to step 6:
106 divided by 99 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4941.0
The remainder is 7 after subtracting 99 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 99 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4941.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
99 goes into 700 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 4941.07
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 99, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 4941.07
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
99 can be fit into 700 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 4941.0707
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
70 divided by 99 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4941.0707
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
99 can be fit into 700 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 4941.070707
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
99 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 4941.070707
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
The number 99 fits into 700 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 4941.07070707
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 4941.07070707, with a leftover of 7e-09.
