Let's divide 285253 by 13
We want to figure out the number of times 285253 can be divided by 13.

Going ahead to step 1:
2 divided by 13 is 0 with 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

Advancing to step 2:
When dividing 28 by 13, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 26 from 28, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 13

Moving on to step 3:
The number 13 fits into 25 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 12 after subtracting 13 from 25.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 13

Advancing to step 4:
If we divide 122 by 13, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
The remainder is 5 after subtracting 117 from 122.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 13

Advancing to step 5:
13 can be fit into 55 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 2194.0
If we take 52 away from 55, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 13

Step 6:
If we divide 33 by 13, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 21942.0
Subtracting 26 from 33 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21942.5
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 13 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 21942.53
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 21942.538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 21942.5384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
13 goes into 80 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 21942.53846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 21942.538461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21942.5384615
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 21942.53846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 21942.53846153, with a leftover of 1.1e-08.
