We're dividing 86866323 by 102 
Let's see how many times 102 fits into 86866323.

On to step 1:
102 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 102

Let's proceed to step 2:
102 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 102

Going ahead to step 3:
868 divided by 102 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 816 from 868 to get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 102

Moving on to step 4:
The number 102 fits into 526 5 times, leaving a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 510 away from 526, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 102

On to step 5:
If we divide 166 by 102, we get 1 and a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 851.0
Deduct 102 from 166 and we're left with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 102

Moving on to step 6:
102 can be fit into 643 6 times, resulting in a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 8516.0
If we subtract 612 from 643, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 102

Advancing to step 7:
102 goes into 312 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 85163.0
The remainder is 6 after subtracting 306 from 312.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 102

Going ahead to step 8:
If we divide 63 by 102, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 851630.0
Deduct 0 from 63 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
102 goes into 630 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 851630.6
Subtracting 612 from 630 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
102 goes into 180 1 times with a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 851630.61
If we take 102 away from 180, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
The number 102 fits into 780 7 times, leaving a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 851630.617
If we subtract 714 from 780, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
102 goes into 660 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 851630.6176
Subtract 612 from 660 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
102 goes into 480 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 851630.61764
Subtract 408 from 480 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.

Moving on to step 14:
When dividing 720 by 102, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 851630.617647
Deduct 714 from 720 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
60 divided by 102 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 851630.617647
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
102 can be fit into 600 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 851630.61764705
Subtracting 510 from 600 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 851630.61764705 and a remainder of 9e-08.
