We're dividing 11455397 by 913 
Let's see how many times 913 fits into 11455397.

Going ahead to step 1:
If we divide 1 by 913, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 913

Advancing to step 2:
913 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 913

On to step 3:
913 can be fit into 114 0 times, resulting in a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 114, we end up with 114.
Take the next digit (5) from the dividend and append it to 114, then repeat: 1145 / 913

Moving on to step 4:
913 can be fit into 1145 1 times, resulting in a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 913 from 1145 leaves us with 232.
Include the next digit (5) from the dividend after 232, then repeat: 2325 / 913

Step 5:
When dividing 2325 by 913, we get 2 with a remainder of 499.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1826 from 2325, we get 499.
Grab the next digit (3) from the dividend, add it to 499, then carry on: 4993 / 913

Step 6:
913 goes into 4993 5 times with a remainder of 428.
The next digit of our result is 5. 
Result so far: 125.0
Deduct 4565 from 4993 and we're left with 428.
Include the next digit (9) from the dividend after 428, then repeat: 4289 / 913

Moving on to step 7:
4289 divided by 913 is 4 with a remainder of 637.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
Subtract 3652 from 4289 to get 637.
Take the next digit (7) from the dividend and append it to 637, then repeat: 6377 / 913

Let's proceed to step 8:
913 can be fit into 6377 6 times, resulting in a remainder of 899.
The next digit of our result is 6. 
Result so far: 12546.0
If we subtract 5478 from 6377, we get 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

Advancing to step 9:
The number 913 fits into 8990 9 times, leaving a remainder of 773.
The number 9 becomes the next digit in our result. 
Result so far: 12546.9
If we subtract 8217 from 8990, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Let's proceed to step 10:
913 can be fit into 7730 8 times, resulting in a remainder of 426.
Write down 8 as next digit of the result. 
Result so far: 12546.98
If we take 7304 away from 7730, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 11:
4260 divided by 913 is 4 with a remainder of 608.
Write down 4 as next digit of the result. 
Result so far: 12546.984
If we take 3652 away from 4260, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 12:
913 can be fit into 6080 6 times, resulting in a remainder of 602.
Put 6 as the next digit of the answer. 
Result so far: 12546.9846
If we take 5478 away from 6080, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

On to step 13:
913 can be fit into 6020 6 times, resulting in a remainder of 542.
Use 6 as the next digit of our solution. 
Result so far: 12546.98466
Deduct 5478 from 6020 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

After the division, we end up with 12546.98466 and a remainder of 0.000542.
