715289 ÷ 60 
The aim is to understand the frequency of 60 in 715289.

Step 1:
If we divide 7 by 60, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 60

On to step 2:
If we divide 71 by 60, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 60 from 71 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 60

Step 3:
60 can be fit into 115 1 times, resulting in a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 60 from 115 leaves us with 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 60

Moving on to step 4:
552 divided by 60 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 540 from 552, we get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 60

Step 5:
When dividing 128 by 60, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1192.0
Deduct 120 from 128 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 60

Advancing to step 6:
60 can be fit into 89 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 11921.0
Subtracting 60 from 89 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 60, we get 4 and a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 11921.4
Subtracting 240 from 290 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
60 can be fit into 500 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 11921.48
The remainder is 20 after subtracting 480 from 500.
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.
Record the quotient 3 as the next digit in the result. 
Result so far: 11921.483
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.

Let's proceed to step 10:
60 can be fit into 200 3 times, resulting in a remainder of 20.
The next digit of our result is 3. 
Result so far: 11921.4833
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.

The final result is 11921.4833 with a remainder of 0.0002.
