Let's divide 86308061 by 102
We want to figure out the number of times 86308061 can be divided by 102.

Advancing to step 1:
102 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 102

Advancing to step 2:
The number 102 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 102

Going ahead to step 3:
102 can be fit into 863 8 times, resulting in a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 816 from 863 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 102

Step 4:
102 goes into 470 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 62 after subtracting 408 from 470.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 102

Let's proceed to step 5:
When dividing 628 by 102, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 846.0
Deduct 612 from 628 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 102

Step 6:
If we divide 160 by 102, we get 1 and a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 8461.0
Subtracting 102 from 160 leaves us with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 102

Advancing to step 7:
102 can be fit into 586 5 times, resulting in a remainder of 76.
The next digit of our result is 5. 
Result so far: 84615.0
Subtract 510 from 586 to get 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 102

Step 8:
When dividing 761 by 102, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 846157.0
Deduct 714 from 761 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
102 goes into 470 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 846157.4
The remainder is 62 after subtracting 408 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
If we divide 620 by 102, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 846157.46
The remainder is 8 after subtracting 612 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
102 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 846157.46
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 102 fits into 800 7 times, leaving a remainder of 86.
Write down 7 as next digit of the result. 
Result so far: 846157.4607
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.

Let's proceed to step 13:
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: 846157.46078
If we take 816 away from 860, we end up 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.

Advancing to step 14:
If we divide 440 by 102, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 846157.460784
If we subtract 408 from 440, we 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.

Step 15:
If we divide 320 by 102, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 846157.4607843
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.

Going ahead to step 16:
The number 102 fits into 140 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 846157.46078431
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 846157.46078431 and a remainder of 3.8e-08.
