Let's divide 878089 by 13
We want to divide 878089 by 13.

Advancing to step 1:
If we divide 8 by 13, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 13

Let's proceed to step 2:
13 goes into 87 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 78 from 87 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 13

Going ahead to step 3:
The number 13 fits into 98 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we take 91 away from 98, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 13

On to step 4:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 675.0
If we subtract 65 from 70, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 13

On to step 5:
58 divided by 13 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6754.0
Deduct 52 from 58 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 13

Advancing to step 6:
The number 13 fits into 69 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 67545.0
Subtract 65 from 69 to get 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:
40 divided by 13 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 67545.3
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 67545.3
Subtract 0 from 10 to 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.

Moving on to step 9:
100 divided by 13 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 67545.307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
When dividing 90 by 13, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 67545.3076
If we subtract 78 from 90, we 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:
If we divide 120 by 13, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 67545.30769
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.

Step 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 67545.307692
Subtracting 26 from 30 leaves us 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 13:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 67545.3076923
Subtracting 39 from 40 leaves us with 1.
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:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 67545.3076923
If we subtract 0 from 10, 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.

Our division results in 67545.3076923 with a remaining 1e-08.
