We look at the division of 451464 by 84 
We want to divide 451464 by 84.

On to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 84

Moving on to step 2:
84 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 84

Going ahead to step 3:
The number 84 fits into 451 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 420 away from 451, we end up with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 84

Advancing to step 4:
84 can be fit into 314 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 252 from 314 to get 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 84

Going ahead to step 5:
84 goes into 626 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 537.0
The remainder is 38 after subtracting 588 from 626.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 84

On to step 6:
384 divided by 84 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5374.0
If we take 336 away from 384, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
480 divided by 84 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5374.5
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 5374.57
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 84, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 5374.571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
360 divided by 84 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 5374.5714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 5374.57142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
720 divided by 84 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 5374.571428
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 5374.5714285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 5374.57142857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5374.57142857 with a remainder of 1.2e-08.
