86241674 ÷ 102 
Our goal is to divide 86241674 by 102.

Let's proceed to step 1:
8 divided by 102 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 102

Let's proceed to step 2:
When dividing 86 by 102, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 102

Step 3:
The number 102 fits into 862 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 816 away from 862, we end up with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 102

Moving on to step 4:
464 divided by 102 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 56 after subtracting 408 from 464.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 102

Going ahead to step 5:
102 can be fit into 561 5 times, resulting in a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
The remainder is 51 after subtracting 510 from 561.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 102

Step 6:
516 divided by 102 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 8455.0
Deduct 510 from 516 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 102

Moving on to step 7:
102 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 84550.0
Subtract 0 from 67 to get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 102

Advancing to step 8:
102 can be fit into 674 6 times, resulting in a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 845506.0
The remainder is 62 after subtracting 612 from 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
102 can be fit into 620 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 845506.6
If we subtract 612 from 620, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
102 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 845506.6
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 102, we get 7 with a remainder of 86.
Write down 7 as next digit of the result. 
Result so far: 845506.607
The remainder is 86 after subtracting 714 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
If we divide 860 by 102, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 845506.6078
Subtracting 816 from 860 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 102, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 845506.60784
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
102 can be fit into 320 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 845506.607843
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 15:
When dividing 140 by 102, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 845506.6078431
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 16:
When dividing 380 by 102, we get 3 with a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 845506.60784313
Subtracting 306 from 380 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 845506.60784313 with a remaining 7.4e-08.
