We're dividing 863490 by 13 
Let's see how many times 13 fits into 863490.

Moving on to step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 13

Going ahead to step 2:
When dividing 86 by 13, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 78 from 86, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 13

Advancing to step 3:
13 goes into 83 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 78 from 83 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 13

Advancing to step 4:
If we divide 54 by 13, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 664.0
Deduct 52 from 54 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 13

Moving on to step 5:
The number 13 fits into 29 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 6642.0
The remainder is 3 after subtracting 26 from 29.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 13

Moving on to step 6:
13 goes into 30 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 66422.0
Deduct 26 from 30 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
13 goes into 40 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 66422.3
If we subtract 39 from 40, we 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.

Let's proceed to step 8:
When dividing 10 by 13, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 66422.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 13, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 66422.307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 66422.3076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
120 divided by 13 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 66422.30769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
13 goes into 30 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 66422.307692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 66422.3076923
The remainder is 1 after subtracting 39 from 40.
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 14:
When dividing 10 by 13, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 66422.3076923
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 66422.3076923 with a balance of 1e-08.
