We're dividing 780619 by 86 
Our goal is to divide 780619 by 86.

Advancing to step 1:
86 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 86

Going ahead to step 2:
The number 86 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 86

Let's proceed to step 3:
86 goes into 780 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 774 from 780 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 86

Step 4:
86 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 86

On to step 5:
86 can be fit into 661 7 times, resulting in a remainder of 59.
The next digit of our result is 7. 
Result so far: 907.0
The remainder is 59 after subtracting 602 from 661.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 86

Step 6:
If we divide 599 by 86, we get 6 and a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 9076.0
If we subtract 516 from 599, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
If we divide 830 by 86, we get 9 and a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 9076.9
Deduct 774 from 830 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 9076.96
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 86, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 9076.965
If we subtract 430 from 440, 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 10:
When dividing 100 by 86, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 9076.9651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 9076.96511
If we take 86 away from 140, we end up 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 final result is 9076.96511 with a remainder of 5.4e-05.
