399760 ÷ 60 
We want to divide 399760 by 60.

On to step 1:
When dividing 3 by 60, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 60

On to step 2:
39 divided by 60 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 60

Going ahead to step 3:
60 goes into 399 6 times with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 360 from 399 leaves us with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 60

Advancing to step 4:
60 can be fit into 397 6 times, resulting in a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 360 away from 397, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 60

On to step 5:
When dividing 376 by 60, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 666.0
Deduct 360 from 376 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 60

Moving on to step 6:
The number 60 fits into 160 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 6662.0
The remainder is 40 after subtracting 120 from 160.
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 7:
If we divide 400 by 60, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 6662.6
Subtract 360 from 400 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.

Let's proceed to step 8:
60 can be fit into 400 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6662.66
If we take 360 away from 400, 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.

The quotient of the division is 6662.66, and the remainder is 0.04.
