We're dividing 454040 by 91 
Our goal is to divide 454040 by 91.

Moving on to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 91

Going ahead to step 2:
If we divide 45 by 91, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 91

Moving on to step 3:
91 can be fit into 454 4 times, resulting in a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 364 from 454, we get 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 91

Going ahead to step 4:
If we divide 900 by 91, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 49.0
If we take 819 away from 900, we end up with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 91

Step 5:
When dividing 814 by 91, we get 8 with a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 498.0
Deduct 728 from 814 and we're left with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 91

Step 6:
If we divide 860 by 91, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 4989.0
If we take 819 away from 860, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
91 can be fit into 410 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4989.4
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
When dividing 460 by 91, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4989.45
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
91 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4989.45
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 91 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 4989.4505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
91 can be fit into 450 4 times, resulting in a remainder of 86.
The next digit of our result is 4. 
Result so far: 4989.45054
If we subtract 364 from 450, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
The number 91 fits into 860 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 4989.450549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
The number 91 fits into 410 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 4989.4505494
Subtracting 364 from 410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
If we divide 460 by 91, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4989.45054945
Subtract 455 from 460 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 4989.45054945 with a remaining 5e-09.
