We're dividing 399148 by 60 
Our goal is to divide 399148 by 60.

Moving on to step 1:
60 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 60

Moving on to step 2:
60 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 60

Moving on to step 3:
60 goes into 399 6 times with a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 360 from 399, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 60

Step 4:
The number 60 fits into 391 6 times, leaving a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 360 from 391 leaves us with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 60

Advancing to step 5:
60 goes into 314 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 665.0
If we subtract 300 from 314, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 60

Moving on to step 6:
When dividing 148 by 60, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6652.0
The remainder is 28 after subtracting 120 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
60 can be fit into 280 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 6652.4
If we take 240 away from 280, we end up with 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 8:
If we divide 400 by 60, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6652.46
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
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: 6652.466
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.

The final outcome is 6652.466, with a leftover of 0.004.
