We look at the division of 353078 by 60 
The aim is to understand the frequency of 60 in 353078.

On to step 1:
If we divide 3 by 60, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 60

Step 2:
When dividing 35 by 60, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 60

Let's proceed to step 3:
353 divided by 60 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 300 from 353 and we're left with 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 60

Moving on to step 4:
60 can be fit into 530 8 times, resulting in a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 480 from 530 to get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 60

Going ahead to step 5:
60 can be fit into 507 8 times, resulting in a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 588.0
If we subtract 480 from 507, we get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 60

Advancing to step 6:
If we divide 278 by 60, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 5884.0
Subtract 240 from 278 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
60 can be fit into 380 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5884.6
Subtract 360 from 380 to 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.

Let's proceed to step 8:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 5884.63
Subtract 180 from 200 to 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.

Step 9:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 5884.633
Deduct 180 from 200 and we're left 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.

After the division, we end up with 5884.633 and a remainder of 0.002.
