We're dividing 858720 by 13 
We're looking to find how many times 13 goes into 858720.

On to step 1:
13 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 13

Advancing to step 2:
If we divide 85 by 13, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 78 away from 85, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 13

Moving on to step 3:
78 divided by 13 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 0 after subtracting 78 from 78.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 13

Moving on to step 4:
When dividing 7 by 13, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 13

Step 5:
72 divided by 13 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 6605.0
If we subtract 65 from 72, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 13

Let's proceed to step 6:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 66055.0
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
13 goes into 50 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 66055.3
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 66055.38
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 66055.384
Deduct 52 from 60 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.

Advancing to step 10:
13 goes into 80 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66055.3846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 66055.38461
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 66055.384615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 66055.3846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 66055.38461538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 66055.38461538 with a remaining 6e-09.
