Let's divide 285042 by 13
We want to figure out the number of times 285042 can be divided by 13.

Going ahead to step 1:
If we divide 2 by 13, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 13

Step 2:
When dividing 28 by 13, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 26 away from 28, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 13

On to step 3:
13 goes into 25 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 13 away from 25, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 13

Going ahead to step 4:
If we divide 120 by 13, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
Subtract 117 from 120 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 13

Step 5:
13 can be fit into 34 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2192.0
The remainder is 8 after subtracting 26 from 34.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 13

Let's proceed to step 6:
13 can be fit into 82 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 21926.0
The remainder is 4 after subtracting 78 from 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 21926.3
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.

Moving on to step 8:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 21926.3
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.

Advancing to step 9:
100 divided by 13 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 21926.307
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:
90 divided by 13 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 21926.3076
Deduct 78 from 90 and we're left 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.

Advancing to step 11:
When dividing 120 by 13, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 21926.30769
Deduct 117 from 120 and we're left 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.

Step 12:
When dividing 30 by 13, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 21926.307692
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 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 21926.3076923
Deduct 39 from 40 and we're left 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.

Let's proceed to step 14:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 21926.3076923
Deduct 0 from 10 and we're left 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.

The final result is 21926.3076923 with a remainder of 1e-08.
