779505 divided by 86 
Our goal is to divide 779505 by 86.

Let's proceed to step 1:
86 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 86

On to step 2:
77 divided by 86 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 86

Going ahead to step 3:
86 can be fit into 779 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 774 from 779 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 86

Advancing to step 4:
55 divided by 86 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 86

Going ahead to step 5:
550 divided by 86 is 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 906.0
If we subtract 516 from 550, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 86

Let's proceed to step 6:
When dividing 345 by 86, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 9064.0
Subtract 344 from 345 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 86, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9064.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 9064.01
If we take 86 away from 100, we end up 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.

Step 9:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 9064.011
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 9064.011, and the remainder is 0.0054.
