We look at the division of 458577 by 84 
We're looking to find how many times 84 goes into 458577.

Moving on to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 84

Moving on to step 2:
84 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 84

Let's proceed to step 3:
458 divided by 84 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 38 after subtracting 420 from 458.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 84

Going ahead to step 4:
84 can be fit into 385 4 times, resulting in a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 336 from 385, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 84

Advancing to step 5:
497 divided by 84 is 5 with a remainder of 77.
Use 5 as the next digit of our solution. 
Result so far: 545.0
Subtracting 420 from 497 leaves us with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 84

On to step 6:
The number 84 fits into 777 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5459.0
The remainder is 21 after subtracting 756 from 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 84 fits into 210 2 times, leaving a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 5459.2
Subtract 168 from 210 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
420 divided by 84 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5459.25
If we subtract 420 from 420, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 84, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5459.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
84 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5459.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5459.25 with a remaining 0.0.
