We look at the division of 81550851 by 60 
We want to divide 81550851 by 60.

Step 1:
If we divide 8 by 60, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 60

Step 2:
81 divided by 60 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 60 from 81, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 60

On to step 3:
When dividing 215 by 60, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 180 from 215 leaves us with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 60

Advancing to step 4:
When dividing 355 by 60, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 300 from 355 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 60

Step 5:
550 divided by 60 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 1359.0
Subtracting 540 from 550 leaves us with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 60

Moving on to step 6:
When dividing 108 by 60, we get 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 13591.0
If we take 60 away from 108, we end up with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 60

Let's proceed to step 7:
When dividing 485 by 60, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 135918.0
Subtracting 480 from 485 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 60

Let's proceed to step 8:
The number 60 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 1359180.0
Subtracting 0 from 51 leaves us 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.

On to step 9:
If we divide 510 by 60, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 1359180.8
If we take 480 away from 510, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 60, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1359180.85
Deduct 300 from 300 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.

Moving on to step 11:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1359180.85
Deduct 0 from 0 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.

On to step 12:
When dividing 0 by 60, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1359180.85
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 quotient of the division is 1359180.85, and the remainder is 0.0.
