We look at the division of 866209 by 60 
We're looking to find how many times 60 goes into 866209.

Advancing to step 1:
60 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 60

On to step 2:
If we divide 86 by 60, we get 1 and a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 26 after subtracting 60 from 86.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 60

On to step 3:
If we divide 266 by 60, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 240 from 266 to get 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 60

Let's proceed to step 4:
If we divide 262 by 60, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Deduct 240 from 262 and we're left with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 60

Going ahead to step 5:
If we divide 220 by 60, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 1443.0
If we subtract 180 from 220, we get 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 60

Moving on to step 6:
60 goes into 409 6 times with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 14436.0
The remainder is 49 after subtracting 360 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
If we divide 490 by 60, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 14436.8
Deduct 480 from 490 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
60 can be fit into 100 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 14436.81
Subtract 60 from 100 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
When dividing 400 by 60, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 14436.816
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
The number 60 fits into 400 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 14436.8166
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 14436.8166 with a remaining 0.0004.
