399078 ÷ 60 
Our goal is to divide 399078 by 60.

Advancing to step 1:
The number 60 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 60

Step 2:
When dividing 39 by 60, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 60

Step 3:
When dividing 399 by 60, we get 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 360 away from 399, we end up with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 60

Step 4:
60 can be fit into 390 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 360 from 390 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 60

Let's proceed to step 5:
60 can be fit into 307 5 times, resulting in a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Subtract 300 from 307 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 60

Advancing to step 6:
60 can be fit into 78 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 6651.0
If we take 60 away from 78, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 60 fits into 180 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 6651.3
Deduct 180 from 180 and we're left 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.

Let's proceed to step 8:
When dividing 0 by 60, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6651.3
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.

Step 9:
0 divided by 60 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6651.3
Subtracting 0 from 0 leaves us 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 6651.3 and a remainder of 0.0.
