87871064 ÷ 424 
Our goal is to divide 87871064 by 424.

Let's proceed to step 1:
When dividing 8 by 424, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 424

Advancing to step 2:
87 divided by 424 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 424

Moving on to step 3:
424 can be fit into 878 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 30 after subtracting 848 from 878.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 424

Step 4:
When dividing 307 by 424, we get 0 with a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 307 after subtracting 0 from 307.
Include the next digit (1) from the dividend after 307, then repeat: 3071 / 424

Let's proceed to step 5:
The number 424 fits into 3071 7 times, leaving a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtract 2968 from 3071 to get 103.
Grab the next digit (0) from the dividend, add it to 103, then carry on: 1030 / 424

Let's proceed to step 6:
The number 424 fits into 1030 2 times, leaving a remainder of 182.
Put 2 as the next digit of the answer. 
Result so far: 2072.0
If we subtract 848 from 1030, we get 182.
Grab the next digit (6) from the dividend, add it to 182, then carry on: 1826 / 424

Advancing to step 7:
When dividing 1826 by 424, we get 4 with a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 20724.0
If we subtract 1696 from 1826, we get 130.
Append the next digit (4) from the dividend to 130 and continue with: 1304 / 424

Advancing to step 8:
If we divide 1304 by 424, we get 3 and a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 207243.0
Subtract 1272 from 1304 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
If we divide 320 by 424, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 207243.0
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
424 goes into 3200 7 times with a remainder of 232.
Write down 7 as next digit of the result. 
Result so far: 207243.07
If we take 2968 away from 3200, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
When dividing 2320 by 424, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 207243.075
The remainder is 200 after subtracting 2120 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
424 goes into 2000 4 times with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 207243.0754
The remainder is 304 after subtracting 1696 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
3040 divided by 424 is 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 207243.07547
Subtracting 2968 from 3040 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
If we divide 720 by 424, we get 1 and a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 207243.075471
The remainder is 296 after subtracting 424 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 15:
424 can be fit into 2960 6 times, resulting in a remainder of 416.
The next digit of our result is 6. 
Result so far: 207243.0754716
If we subtract 2544 from 2960, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 16:
4160 divided by 424 is 9 with a remainder of 344.
The number 9 becomes the next digit in our result. 
Result so far: 207243.07547169
Deduct 3816 from 4160 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 207243.07547169, and the remainder is 3.44e-07.
