171216 divided by 60 
The aim is to understand the frequency of 60 in 171216.

Advancing to step 1:
When dividing 1 by 60, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 60

Advancing to step 2:
60 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 60

Moving on to step 3:
60 goes into 171 2 times with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 120 from 171 and we're left with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 60

Step 4:
When dividing 512 by 60, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 480 away from 512, we end up with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 60

Step 5:
321 divided by 60 is 5 with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Subtracting 300 from 321 leaves us with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 60

On to step 6:
When dividing 216 by 60, we get 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 2853.0
Subtracting 180 from 216 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 60 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2853.6
Subtract 360 from 360 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.

Step 8:
If we divide 0 by 60, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2853.6
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.

Moving on 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: 2853.6
If we subtract 0 from 0, we 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.

Our division results in 2853.6 with a remaining 0.0.
