Let's divide 213321 by 60
The aim is to understand the frequency of 60 in 213321.

Going ahead to step 1:
2 divided by 60 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 60

Step 2:
When dividing 21 by 60, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 60

Moving on to step 3:
The number 60 fits into 213 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 180 from 213 and we're left with 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 60

Going ahead to step 4:
60 goes into 333 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 300 from 333, we get 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 60

Step 5:
When dividing 332 by 60, we get 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 355.0
Subtracting 300 from 332 leaves us with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 60

Moving on to step 6:
321 divided by 60 is 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 3555.0
If we subtract 300 from 321, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 60 is 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3555.3
Deduct 180 from 210 and we're left 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.

On to step 8:
The number 60 fits into 300 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3555.35
If we subtract 300 from 300, 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.

Let's proceed to step 9:
When dividing 0 by 60, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3555.35
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.

Step 10:
0 divided by 60 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3555.35
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 final outcome is 3555.35, with a leftover of 0.0.
