We look at the division of 596780 by 86 
We want to divide 596780 by 86.

On to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 86

On to step 2:
If we divide 59 by 86, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 86

Going ahead to step 3:
86 can be fit into 596 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 516 from 596 and we're left with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 86

On to step 4:
86 goes into 807 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we take 774 away from 807, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 86

Going ahead to step 5:
338 divided by 86 is 3 with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 693.0
Deduct 258 from 338 and we're left with 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 86

On to step 6:
When dividing 800 by 86, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 6939.0
The remainder is 26 after subtracting 774 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 86, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 6939.3
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6939.3
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 86 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 6939.302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 86, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 6939.3023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 6939.30232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
480 divided by 86 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6939.302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
86 goes into 500 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 6939.3023255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 6939.3023255 with a remainder of 7e-07.
