Let's divide 11259121 by 13
Let's see how many times 13 fits into 11259121.

Advancing to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 13

Step 2:
13 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 13

Advancing to step 3:
When dividing 112 by 13, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
If we take 104 away from 112, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 13

Advancing to step 4:
85 divided by 13 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 86.0
The remainder is 7 after subtracting 78 from 85.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 13

Let's proceed to step 5:
13 goes into 79 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
If we subtract 78 from 79, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 13

Advancing to step 6:
13 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 8660.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 13

Step 7:
112 divided by 13 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 86608.0
The remainder is 8 after subtracting 104 from 112.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 13

Moving on to step 8:
13 goes into 81 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 866086.0
If we take 78 away from 81, 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.

Let's proceed to step 9:
When dividing 30 by 13, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 866086.2
Subtracting 26 from 30 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 10:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 866086.23
Subtract 39 from 40 to 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.

Step 11:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 866086.23
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 12:
100 divided by 13 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 866086.2307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 866086.23076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
When dividing 120 by 13, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 866086.230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 15:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 866086.2307692
Subtracting 26 from 30 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.

Going ahead to step 16:
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: 866086.23076923
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.

After the division, we end up with 866086.23076923 and a remainder of 1e-09.
