782406 ÷ 86 
We want to divide 782406 by 86.

On to step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 86

Going ahead to step 2:
86 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 86

Going ahead to step 3:
When dividing 782 by 86, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 774 from 782, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 86

Let's proceed to step 4:
The number 86 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 86

Moving on to step 5:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 909.0
If we subtract 774 from 840, we get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 86

On to step 6:
If we divide 666 by 86, we get 7 and a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 9097.0
Deduct 602 from 666 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
640 divided by 86 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 9097.7
If we take 602 away from 640, 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.

On to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9097.74
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
When dividing 360 by 86, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9097.744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9097.744 with a remainder of 0.0016.
