We look at the division of 213371 by 60 
The aim is to understand the frequency of 60 in 213371.

Advancing to step 1:
60 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 60

Advancing to step 2:
21 divided by 60 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 60

Let's proceed to step 3:
213 divided by 60 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 180 from 213 to get 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 60

Advancing to step 4:
If we divide 333 by 60, we get 5 and a remainder of 33.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 300 from 333 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 60

Let's proceed to step 5:
60 can be fit into 337 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 355.0
Subtracting 300 from 337 leaves us with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 60

Going ahead to step 6:
When dividing 371 by 60, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 3556.0
If we take 360 away from 371, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 60 fits into 110 1 times, leaving a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 3556.1
The remainder is 50 after subtracting 60 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
60 can be fit into 500 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3556.18
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3556.183
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 60 is 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 3556.1833
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3556.1833 with a remaining 0.0002.
