We look at the division of 753999 by 60 
The aim is to understand the frequency of 60 in 753999.

Let's proceed to step 1:
7 divided by 60 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 60

On to step 2:
75 divided by 60 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 60 away from 75, we end up with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 60

Let's proceed to step 3:
60 goes into 153 2 times with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 33 after subtracting 120 from 153.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 60

On to step 4:
If we divide 339 by 60, we get 5 and a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 125.0
Deduct 300 from 339 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 60

On to step 5:
If we divide 399 by 60, we get 6 and a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 1256.0
If we take 360 away from 399, we end up with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 60

Let's proceed to step 6:
The number 60 fits into 399 6 times, leaving a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 12566.0
Subtracting 360 from 399 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 60, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 12566.6
If we take 360 away from 390, 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.

Going ahead to step 8:
If we divide 300 by 60, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12566.65
Deduct 300 from 300 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.

Moving on to step 9:
60 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12566.65
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.

Step 10:
0 divided by 60 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12566.65
If we subtract 0 from 0, 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.

After the division, we end up with 12566.65 and a remainder of 0.0.
