Let's divide 780039 by 86
We want to figure out the number of times 780039 can be divided by 86.

Moving on to step 1:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 86

Step 2:
If we divide 78 by 86, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 86

Step 3:
780 divided by 86 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 6 after subtracting 774 from 780.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 86

Advancing to step 4:
86 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 90.0
The remainder is 60 after subtracting 0 from 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 86

Going ahead to step 5:
86 can be fit into 603 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 907.0
Subtract 602 from 603 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 86

Moving on to step 6:
86 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 9070.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 86, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 9070.2
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
The number 86 fits into 180 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9070.22
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 9070.22 with a remaining 0.008.
