We divide 816120 by 60
We're looking to find how many times 60 goes into 816120.

On to step 1:
60 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 60

On to step 2:
81 divided by 60 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 60 from 81 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 60

On to step 3:
The number 60 fits into 216 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 180 from 216 leaves us with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 60

Let's proceed to step 4:
361 divided by 60 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 136.0
Subtracting 360 from 361 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 60

Let's proceed to step 5:
12 divided by 60 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1360.0
If we subtract 0 from 12, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 60

Let's proceed to step 6:
The number 60 fits into 120 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 13602.0
Subtracting 120 from 120 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.

Advancing to step 7:
When dividing 0 by 60, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13602.0
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.

Step 8:
If we divide 0 by 60, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13602.0
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.

The final outcome is 13602.0, with a leftover of 0.0.
