We look at the division of 870402 by 13 
Our goal is to divide 870402 by 13.

Going ahead to step 1:
8 divided by 13 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 13

Step 2:
87 divided by 13 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 9 after subtracting 78 from 87.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 13

Let's proceed to step 3:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 12 after subtracting 78 from 90.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 13

On to step 4:
13 can be fit into 124 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 669.0
Subtracting 117 from 124 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 13

Moving on to step 5:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6695.0
The remainder is 5 after subtracting 65 from 70.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 13

Advancing to step 6:
52 divided by 13 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 66954.0
The remainder is 0 after subtracting 52 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66954.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 13 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 66954.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 66954.0, with a leftover of 0.0.
