We're dividing 143969 by 13 
We're looking to find how many times 13 goes into 143969.

Let's proceed to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 13

Let's proceed to step 2:
14 divided by 13 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 13 from 14.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 13

Step 3:
13 goes into 13 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 0 after subtracting 13 from 13.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 13

Advancing to step 4:
9 divided by 13 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 13

Step 5:
If we divide 96 by 13, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1107.0
If we subtract 91 from 96, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 13

Advancing to step 6:
When dividing 59 by 13, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 11074.0
If we subtract 52 from 59, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11074.5
If we take 65 away from 70, we end up 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.

On to step 8:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 11074.53
If we subtract 39 from 50, we 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.

On to step 9:
When dividing 110 by 13, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 11074.538
Subtract 104 from 110 to get 6.
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:
13 goes into 60 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11074.5384
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 11074.53846
The remainder is 2 after subtracting 78 from 80.
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:
20 divided by 13 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 11074.538461
Deduct 13 from 20 and we're left 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.

Advancing to step 13:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 11074.5384615
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.

Let's proceed to step 14:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 11074.53846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 11074.53846153 with a balance of 1.1e-08.
