We look at the division of 4209841 by 487 
We want to figure out the number of times 4209841 can be divided by 487.

Moving on to step 1:
If we divide 4 by 487, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 487

Step 2:
The number 487 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 487

On to step 3:
487 goes into 420 0 times with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 420 leaves us with 420.
Grab the next digit (9) from the dividend, add it to 420, then carry on: 4209 / 487

Going ahead to step 4:
The number 487 fits into 4209 8 times, leaving a remainder of 313.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 3896 from 4209 and we're left with 313.
Take the next digit (8) from the dividend and append it to 313, then repeat: 3138 / 487

Moving on to step 5:
487 goes into 3138 6 times with a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 2922 from 3138 and we're left with 216.
Include the next digit (4) from the dividend after 216, then repeat: 2164 / 487

Going ahead to step 6:
487 goes into 2164 4 times with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 864.0
If we take 1948 away from 2164, we end up with 216.
Append the next digit (1) from the dividend to 216 and continue with: 2161 / 487

Advancing to step 7:
If we divide 2161 by 487, we get 4 and a remainder of 213.
Write down 4 as next digit of the result. 
Result so far: 8644.0
If we take 1948 away from 2161, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 8:
487 goes into 2130 4 times with a remainder of 182.
Use 4 as the next digit of our solution. 
Result so far: 8644.4
Subtract 1948 from 2130 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 9:
The number 487 fits into 1820 3 times, leaving a remainder of 359.
The next digit of our result is 3. 
Result so far: 8644.43
The remainder is 359 after subtracting 1461 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 10:
If we divide 3590 by 487, we get 7 and a remainder of 181.
The number 7 becomes the next digit in our result. 
Result so far: 8644.437
Subtracting 3409 from 3590 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 11:
1810 divided by 487 is 3 with a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 8644.4373
If we take 1461 away from 1810, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 12:
487 can be fit into 3490 7 times, resulting in a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 8644.43737
Subtracting 3409 from 3490 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 13:
810 divided by 487 is 1 with a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 8644.437371
If we subtract 487 from 810, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 14:
When dividing 3230 by 487, we get 6 with a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 8644.4373716
Deduct 2922 from 3230 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 15:
487 goes into 3080 6 times with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 8644.43737166
If we take 2922 away from 3080, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

In conclusion, the division gives 8644.43737166 with a balance of 1.58e-07.
