We're dividing 31085378 by 60 
The aim is to understand the frequency of 60 in 31085378.

Advancing to step 1:
The number 60 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 60

Advancing to step 2:
60 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 60

Let's proceed to step 3:
If we divide 310 by 60, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 300 from 310 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 60

On to step 4:
60 can be fit into 108 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 60 away from 108, we end up with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 60

Going ahead to step 5:
If we divide 485 by 60, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 518.0
Deduct 480 from 485 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 60

Advancing to step 6:
When dividing 53 by 60, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 5180.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 60

Step 7:
60 can be fit into 537 8 times, resulting in a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 51808.0
If we take 480 away from 537, we end up with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 60

Advancing to step 8:
578 divided by 60 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 518089.0
If we take 540 away from 578, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 60, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 518089.6
The remainder is 20 after subtracting 360 from 380.
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:
When dividing 200 by 60, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 518089.63
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 60 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 518089.633
The remainder is 20 after subtracting 180 from 200.
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 outcome is 518089.633, with a leftover of 0.002.
