We look at the division of 13390834 by 454 
We want to divide 13390834 by 454.

Let's proceed to step 1:
454 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 454

Step 2:
454 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 454

Moving on to step 3:
133 divided by 454 is 0 with a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 133 leaves us with 133.
Take the next digit (9) from the dividend and append it to 133, then repeat: 1339 / 454

Advancing to step 4:
If we divide 1339 by 454, we get 2 and a remainder of 431.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 908 from 1339 to get 431.
Bring next digit (0) of the dividend behind the 431 and repeat the process: 4310 / 454

Let's proceed to step 5:
The number 454 fits into 4310 9 times, leaving a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 224 after subtracting 4086 from 4310.
Take the next digit (8) from the dividend and append it to 224, then repeat: 2248 / 454

On to step 6:
2248 divided by 454 is 4 with a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 294.0
The remainder is 432 after subtracting 1816 from 2248.
Include the next digit (3) from the dividend after 432, then repeat: 4323 / 454

Going ahead to step 7:
When dividing 4323 by 454, we get 9 with a remainder of 237.
Record the quotient 9 as the next digit in the result. 
Result so far: 2949.0
Subtracting 4086 from 4323 leaves us with 237.
Take the next digit (4) from the dividend and append it to 237, then repeat: 2374 / 454

Step 8:
2374 divided by 454 is 5 with a remainder of 104.
The next digit of our result is 5. 
Result so far: 29495.0
Subtracting 2270 from 2374 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 9:
454 can be fit into 1040 2 times, resulting in a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 29495.2
If we take 908 away from 1040, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
454 goes into 1320 2 times with a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 29495.22
Subtract 908 from 1320 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The final result is 29495.22 with a remainder of 0.412.
