We're dividing 16585974 by 489 
We want to divide 16585974 by 489.

On to step 1:
If we divide 1 by 489, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 489

Going ahead to step 2:
If we divide 16 by 489, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 489

On to step 3:
When dividing 165 by 489, we get 0 with a remainder of 165.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 165 and we're left with 165.
Fetch the next digit (8) from the dividend, attach it to 165 and continue: 1658 / 489

Moving on to step 4:
When dividing 1658 by 489, we get 3 with a remainder of 191.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1467 from 1658, we get 191.
Fetch the next digit (5) from the dividend, attach it to 191 and continue: 1915 / 489

On to step 5:
1915 divided by 489 is 3 with a remainder of 448.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 1467 away from 1915, we end up with 448.
Grab the next digit (9) from the dividend, add it to 448, then carry on: 4489 / 489

Moving on to step 6:
The number 489 fits into 4489 9 times, leaving a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 339.0
Deduct 4401 from 4489 and we're left with 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 489

Going ahead to step 7:
887 divided by 489 is 1 with a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 3391.0
The remainder is 398 after subtracting 489 from 887.
Append the next digit (4) from the dividend to 398 and continue with: 3984 / 489

Going ahead to step 8:
The number 489 fits into 3984 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 33918.0
Subtract 3912 from 3984 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
720 divided by 489 is 1 with a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 33918.1
Subtracting 489 from 720 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 10:
The number 489 fits into 2310 4 times, leaving a remainder of 354.
The next digit of our result is 4. 
Result so far: 33918.14
If we take 1956 away from 2310, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 11:
489 can be fit into 3540 7 times, resulting in a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 33918.147
If we take 3423 away from 3540, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 12:
489 can be fit into 1170 2 times, resulting in a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 33918.1472
Subtracting 978 from 1170 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
The number 489 fits into 1920 3 times, leaving a remainder of 453.
The next digit of our result is 3. 
Result so far: 33918.14723
Deduct 1467 from 1920 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 14:
4530 divided by 489 is 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 33918.147239
Deduct 4401 from 4530 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 15:
1290 divided by 489 is 2 with a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 33918.1472392
Subtracting 978 from 1290 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 16:
If we divide 3120 by 489, we get 6 and a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 33918.14723926
Subtract 2934 from 3120 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

After the division, we end up with 33918.14723926 and a remainder of 1.86e-07.
