We look at the division of 813111 by 60 
We want to divide 813111 by 60.

Advancing to step 1:
The number 60 fits into 8 0 times, leaving 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.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 60

Going ahead to step 2:
The number 60 fits into 81 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 60 from 81 to get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 60

Advancing to step 3:
If we divide 213 by 60, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 180 from 213 leaves us with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 60

Moving on to step 4:
60 can be fit into 331 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 300 from 331, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 60

Moving on to step 5:
60 can be fit into 311 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 1355.0
Subtracting 300 from 311 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 60

Moving on to step 6:
111 divided by 60 is 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 13551.0
If we take 60 away from 111, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
When dividing 510 by 60, we get 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 13551.8
Subtract 480 from 510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 60, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 13551.85
Subtract 300 from 300 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 60, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13551.85
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.

Advancing to step 10:
60 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13551.85
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.

The final result is 13551.85 with a remainder of 0.0.
