We look at the division of 287198 by 60 
We want to figure out the number of times 287198 can be divided by 60.

On to step 1:
When dividing 2 by 60, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 60

On to step 2:
If we divide 28 by 60, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 60

Step 3:
If we divide 287 by 60, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 240 from 287, we get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 60

Let's proceed to step 4:
The number 60 fits into 471 7 times, leaving a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 420 away from 471, we end up with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 60

On to step 5:
519 divided by 60 is 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 478.0
The remainder is 39 after subtracting 480 from 519.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 60

Going ahead to step 6:
398 divided by 60 is 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 4786.0
Deduct 360 from 398 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 60 fits into 380 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 4786.6
The remainder is 20 after subtracting 360 from 380.
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:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 4786.63
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.

On to step 9:
When dividing 200 by 60, we get 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 4786.633
Subtracting 180 from 200 leaves us 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.

The final outcome is 4786.633, with a leftover of 0.002.
