We're dividing 7923984 by 487 
We want to divide 7923984 by 487.

Going ahead to step 1:
If we divide 7 by 487, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 487

Let's proceed to step 2:
If we divide 79 by 487, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 487

Moving on to step 3:
792 divided by 487 is 1 with a remainder of 305.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 487 from 792 and we're left with 305.
Take the next digit (3) from the dividend and append it to 305, then repeat: 3053 / 487

Step 4:
The number 487 fits into 3053 6 times, leaving a remainder of 131.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 2922 from 3053 leaves us with 131.
Bring next digit (9) of the dividend behind the 131 and repeat the process: 1319 / 487

Advancing to step 5:
487 can be fit into 1319 2 times, resulting in a remainder of 345.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Deduct 974 from 1319 and we're left with 345.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 487

On to step 6:
If we divide 3458 by 487, we get 7 and a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 1627.0
The remainder is 49 after subtracting 3409 from 3458.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 487

On to step 7:
487 can be fit into 494 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 16271.0
The remainder is 7 after subtracting 487 from 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
If we divide 70 by 487, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 16271.0
Deduct 0 from 70 and we're left with 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 9:
If we divide 700 by 487, we get 1 and a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 16271.01
Deduct 487 from 700 and we're left 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 10:
487 can be fit into 2130 4 times, resulting in a remainder of 182.
Use 4 as the next digit of our solution. 
Result so far: 16271.014
Subtracting 1948 from 2130 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 11:
487 can be fit into 1820 3 times, resulting in a remainder of 359.
The number 3 becomes the next digit in our result. 
Result so far: 16271.0143
If we take 1461 away from 1820, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 12:
487 can be fit into 3590 7 times, resulting in a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 16271.01437
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.

On to step 13:
1810 divided by 487 is 3 with a remainder of 349.
Use 3 as the next digit of our solution. 
Result so far: 16271.014373
If we subtract 1461 from 1810, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 14:
487 can be fit into 3490 7 times, resulting in a remainder of 81.
The next digit of our result is 7. 
Result so far: 16271.0143737
Deduct 3409 from 3490 and we're left 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.

Going ahead to step 15:
When dividing 810 by 487, we get 1 with a remainder of 323.
Put 1 as the next digit of the answer. 
Result so far: 16271.01437371
Subtracting 487 from 810 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

The final result is 16271.01437371 with a remainder of 3.23e-07.
