We divide 1243129 by 13
Let's see how many times 13 fits into 1243129.

Advancing to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 13

On to step 2:
13 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 13

Step 3:
When dividing 124 by 13, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 117 from 124 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 13

Let's proceed to step 4:
73 divided by 13 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 65 from 73 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 13

On to step 5:
13 goes into 81 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 956.0
Subtracting 78 from 81 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 13

Going ahead to step 6:
13 can be fit into 32 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 9562.0
If we subtract 26 from 32, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 13

On to step 7:
When dividing 69 by 13, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 95625.0
Subtracting 65 from 69 leaves us 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.

Advancing to step 8:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 95625.3
Subtracting 39 from 40 leaves us 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.

Advancing to step 9:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 95625.3
Subtract 0 from 10 to 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.

Going ahead to step 10:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 95625.307
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.

Step 11:
90 divided by 13 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 95625.3076
Subtracting 78 from 90 leaves us 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.

Moving on to step 12:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 95625.30769
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 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 95625.307692
If we subtract 26 from 30, we get 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 14:
If we divide 40 by 13, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 95625.3076923
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.

Advancing to step 15:
When dividing 10 by 13, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 95625.3076923
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.

In conclusion, the division gives 95625.3076923 with a balance of 1e-08.
