We look at the division of 807477 by 60 
The aim is to understand the frequency of 60 in 807477.

On to step 1:
8 divided by 60 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 60

Step 2:
60 goes into 80 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 60 from 80 to get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 60

Let's proceed to step 3:
When dividing 207 by 60, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 180 from 207 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 60

Moving on to step 4:
60 can be fit into 274 4 times, resulting in a remainder of 34.
The next digit of our result is 4. 
Result so far: 134.0
The remainder is 34 after subtracting 240 from 274.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 60

Let's proceed to step 5:
60 can be fit into 347 5 times, resulting in a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 1345.0
Subtracting 300 from 347 leaves us with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 60

Going ahead to step 6:
60 goes into 477 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 13457.0
Subtract 420 from 477 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
570 divided by 60 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 13457.9
If we subtract 540 from 570, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 60, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13457.95
The remainder is 0 after subtracting 300 from 300.
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 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13457.95
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.

Advancing to step 10:
60 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13457.95
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.

The final outcome is 13457.95, with a leftover of 0.0.
