13608021 ÷ 487 
Let's see how many times 487 fits into 13608021.

Step 1:
If we divide 1 by 487, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 487

Going ahead to step 2:
When dividing 13 by 487, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 487

Moving on to step 3:
487 goes into 136 0 times with a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 136, we end up with 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 487

Moving on to step 4:
1360 divided by 487 is 2 with a remainder of 386.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 386 after subtracting 974 from 1360.
Append the next digit (8) from the dividend to 386 and continue with: 3868 / 487

Let's proceed to step 5:
The number 487 fits into 3868 7 times, leaving a remainder of 459.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 3409 from 3868 to get 459.
Include the next digit (0) from the dividend after 459, then repeat: 4590 / 487

Let's proceed to step 6:
If we divide 4590 by 487, we get 9 and a remainder of 207.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we subtract 4383 from 4590, we get 207.
Include the next digit (2) from the dividend after 207, then repeat: 2072 / 487

Step 7:
When dividing 2072 by 487, we get 4 with a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 2794.0
Subtract 1948 from 2072 to get 124.
Grab the next digit (1) from the dividend, add it to 124, then carry on: 1241 / 487

On to step 8:
When dividing 1241 by 487, we get 2 with a remainder of 267.
The number 2 becomes the next digit in our result. 
Result so far: 27942.0
The remainder is 267 after subtracting 974 from 1241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 9:
The number 487 fits into 2670 5 times, leaving a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 27942.5
Subtracting 2435 from 2670 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 10:
If we divide 2350 by 487, we get 4 and a remainder of 402.
Record the quotient 4 as the next digit in the result. 
Result so far: 27942.54
If we subtract 1948 from 2350, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 11:
If we divide 4020 by 487, we get 8 and a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 27942.548
Subtracting 3896 from 4020 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 12:
487 can be fit into 1240 2 times, resulting in a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 27942.5482
Subtracting 974 from 1240 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 13:
487 goes into 2660 5 times with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 27942.54825
Deduct 2435 from 2660 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 14:
2250 divided by 487 is 4 with a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 27942.548254
If we subtract 1948 from 2250, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 15:
3020 divided by 487 is 6 with a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 27942.5482546
Deduct 2922 from 3020 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
The number 487 fits into 980 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 27942.54825462
If we subtract 974 from 980, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 27942.54825462 and a remainder of 6e-09.
