We divide 21147 by 60
The aim is to understand the frequency of 60 in 21147.

On to step 1:
If we divide 2 by 60, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 60

Moving on to step 2:
The number 60 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 60

Step 3:
60 goes into 211 3 times with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 180 from 211, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 60

Let's proceed to step 4:
The number 60 fits into 314 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 300 away from 314, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 60

Going ahead to step 5:
The number 60 fits into 147 2 times, leaving a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
If we take 120 away from 147, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 6:
270 divided by 60 is 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 352.4
If we take 240 away from 270, 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.

Moving on to step 7:
60 can be fit into 300 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 352.45
Subtracting 300 from 300 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.

Let's proceed to step 8:
When dividing 0 by 60, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 352.45
Subtract 0 from 0 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.

Advancing to step 9:
0 divided by 60 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 352.45
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.

Our division results in 352.45 with a remaining 0.0.
