13243784 divided by 454 
We want to figure out the number of times 13243784 can be divided by 454.

Let's proceed to step 1:
454 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 454

Moving on to step 2:
When dividing 13 by 454, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 454

Step 3:
132 divided by 454 is 0 with a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 132 and we're left with 132.
Include the next digit (4) from the dividend after 132, then repeat: 1324 / 454

Going ahead to step 4:
If we divide 1324 by 454, we get 2 and a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 416 after subtracting 908 from 1324.
Fetch the next digit (3) from the dividend, attach it to 416 and continue: 4163 / 454

Moving on to step 5:
If we divide 4163 by 454, we get 9 and a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 4086 away from 4163, we end up with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 454

Advancing to step 6:
454 can be fit into 777 1 times, resulting in a remainder of 323.
Put 1 as the next digit of the answer. 
Result so far: 291.0
If we subtract 454 from 777, we get 323.
Grab the next digit (8) from the dividend, add it to 323, then carry on: 3238 / 454

Advancing to step 7:
When dividing 3238 by 454, we get 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 2917.0
If we take 3178 away from 3238, we end up with 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 454

Advancing to step 8:
When dividing 604 by 454, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 29171.0
Deduct 454 from 604 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
When dividing 1500 by 454, we get 3 with a remainder of 138.
The number 3 becomes the next digit in our result. 
Result so far: 29171.3
If we take 1362 away from 1500, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
When dividing 1380 by 454, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 29171.33
Deduct 1362 from 1380 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 29171.33, with a leftover of 0.018.
