We look at the division of 454840 by 84 
We're looking to find how many times 84 goes into 454840.

Step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
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 / 84

Moving on to step 2:
If we divide 45 by 84, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 84

Let's proceed to step 3:
84 can be fit into 454 5 times, resulting in a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 420 away from 454, we end up with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 84

Going ahead to step 4:
When dividing 348 by 84, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 336 from 348 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 84

Step 5:
124 divided by 84 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
Subtracting 84 from 124 leaves us with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 84

Let's proceed to step 6:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 5414.0
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
If we divide 640 by 84, we get 7 and a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 5414.7
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 5414.76
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
160 divided by 84 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 5414.761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
When dividing 760 by 84, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 5414.7619
If we take 756 away from 760, we end up 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.

On to step 11:
84 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5414.7619
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 84 fits into 400 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 5414.761904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 5414.7619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
84 goes into 520 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 5414.76190476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 5414.76190476 with a remainder of 1.6e-08.
