455900 ÷ 60 
Our goal is to divide 455900 by 60.

Step 1:
The number 60 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 60

Advancing to step 2:
When dividing 45 by 60, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 60

Let's proceed to step 3:
If we divide 455 by 60, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 420 from 455, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 60

Let's proceed to step 4:
When dividing 359 by 60, we get 5 with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 300 from 359 leaves us with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 60

Step 5:
60 can be fit into 590 9 times, resulting in a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 759.0
The remainder is 50 after subtracting 540 from 590.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 60

Going ahead to step 6:
60 can be fit into 500 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 7598.0
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 60 fits into 200 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 7598.3
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 7598.33
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 7598.33 with a remaining 0.02.
