We're dividing 16553777 by 86 
We want to divide 16553777 by 86.

On to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 86

Let's proceed to step 2:
The number 86 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 86

Advancing to step 3:
The number 86 fits into 165 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 165 to get 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 86

Step 4:
86 goes into 795 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 774 from 795 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 86

On to step 5:
When dividing 213 by 86, we get 2 with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
Deduct 172 from 213 and we're left with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 86

On to step 6:
When dividing 417 by 86, we get 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 1924.0
Subtract 344 from 417 to get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 86

On to step 7:
737 divided by 86 is 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 19248.0
Subtracting 688 from 737 leaves us with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 86

Advancing to step 8:
When dividing 497 by 86, we get 5 with a remainder of 67.
The next digit of our result is 5. 
Result so far: 192485.0
Subtract 430 from 497 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
86 goes into 670 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 192485.7
Deduct 602 from 670 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
If we divide 680 by 86, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 192485.77
Deduct 602 from 680 and we're left 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.

After the division, we end up with 192485.77 and a remainder of 0.078.
