We divide 857808 by 13
Our goal is to divide 857808 by 13.

Going ahead to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 13

Let's proceed to step 2:
13 can be fit into 85 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 78 from 85 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 13

Moving on to step 3:
13 can be fit into 77 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 65 from 77, we get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 13

Step 4:
13 can be fit into 128 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 659.0
Subtracting 117 from 128 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 13

Let's proceed to step 5:
110 divided by 13 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 6598.0
If we take 104 away from 110, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 13

On to step 6:
If we divide 68 by 13, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 65985.0
If we take 65 away from 68, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 65985.2
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.

Step 8:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 65985.23
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.

Advancing to step 9:
13 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 65985.23
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.

Moving on to step 10:
13 goes into 100 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 65985.2307
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 13, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 65985.23076
If we take 78 away from 90, we end up with 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 12:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 65985.230769
Subtracting 117 from 120 leaves us with 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 13:
If we divide 30 by 13, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 65985.2307692
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.

Moving on to step 14:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 65985.23076923
If we take 39 away from 40, we end up 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.

The final outcome is 65985.23076923, with a leftover of 1e-09.
