We look at the division of 16634365 by 489 
We want to divide 16634365 by 489.

On to step 1:
The number 489 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 489

Let's proceed to step 2:
16 divided by 489 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 489

Advancing to step 3:
489 can be fit into 166 0 times, resulting in a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Fetch the next digit (3) from the dividend, attach it to 166 and continue: 1663 / 489

Advancing to step 4:
The number 489 fits into 1663 3 times, leaving a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1467 away from 1663, we end up with 196.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 489

Moving on to step 5:
489 goes into 1964 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 1956 from 1964 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 489

Moving on to step 6:
The number 489 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 489

On to step 7:
836 divided by 489 is 1 with a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 3401.0
If we subtract 489 from 836, we get 347.
Bring next digit (5) of the dividend behind the 347 and repeat the process: 3475 / 489

Step 8:
If we divide 3475 by 489, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 34017.0
The remainder is 52 after subtracting 3423 from 3475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 489 fits into 520 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 34017.1
Subtracting 489 from 520 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
489 goes into 310 0 times with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 34017.1
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
If we divide 3100 by 489, we get 6 and a remainder of 166.
The next digit of our result is 6. 
Result so far: 34017.106
If we subtract 2934 from 3100, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 12:
489 can be fit into 1660 3 times, resulting in a remainder of 193.
The next digit of our result is 3. 
Result so far: 34017.1063
Subtracting 1467 from 1660 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 13:
1930 divided by 489 is 3 with a remainder of 463.
The number 3 becomes the next digit in our result. 
Result so far: 34017.10633
The remainder is 463 after subtracting 1467 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

The final outcome is 34017.10633, with a leftover of 0.000463.
