859290 ÷ 60 
Our goal is to divide 859290 by 60.

Going ahead to step 1:
8 divided by 60 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 60

Advancing to step 2:
60 can be fit into 85 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 25 after subtracting 60 from 85.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 60

Step 3:
The number 60 fits into 259 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 240 from 259 and we're left with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 60

Advancing to step 4:
If we divide 192 by 60, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we subtract 180 from 192, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 60

Moving on to step 5:
60 can be fit into 129 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 1432.0
The remainder is 9 after subtracting 120 from 129.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 60

Let's proceed to step 6:
60 goes into 90 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 14321.0
If we take 60 away from 90, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 60, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14321.5
If we take 300 away from 300, 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.

Moving on to step 8:
When dividing 0 by 60, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14321.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 60 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14321.5
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.

After the division, we end up with 14321.5 and a remainder of 0.0.
