We're dividing 280721 by 60 
We want to figure out the number of times 280721 can be divided by 60.

Let's proceed to step 1:
60 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 60

Step 2:
If we divide 28 by 60, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 60

Let's proceed to step 3:
When dividing 280 by 60, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 240 away from 280, we end up with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 60

On to step 4:
60 can be fit into 407 6 times, resulting in a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 360 from 407, we get 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 60

Let's proceed to step 5:
When dividing 472 by 60, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
Deduct 420 from 472 and we're left with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 60

Let's proceed to step 6:
When dividing 521 by 60, we get 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 4678.0
If we take 480 away from 521, 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.

Going ahead to step 7:
The number 60 fits into 410 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 4678.6
If we subtract 360 from 410, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 60 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4678.68
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.

Advancing to step 9:
60 goes into 200 3 times with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 4678.683
If we subtract 180 from 200, we 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.

On to step 10:
If we divide 200 by 60, we get 3 and a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 4678.6833
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 4678.6833 with a remaining 0.0002.
