154217 ÷ 60 
The aim is to understand the frequency of 60 in 154217.

On to step 1:
60 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 60

On to step 2:
15 divided by 60 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 60

Going ahead to step 3:
When dividing 154 by 60, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 34 after subtracting 120 from 154.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 60

Going ahead to step 4:
When dividing 342 by 60, we get 5 with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 300 from 342 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 60

On to step 5:
The number 60 fits into 421 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtracting 420 from 421 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 60

Going ahead to step 6:
The number 60 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 2570.0
Subtract 0 from 17 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 60 is 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2570.2
If we take 120 away from 170, we end up 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.

Going ahead to step 8:
If we divide 500 by 60, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 2570.28
Deduct 480 from 500 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.

Advancing to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 2570.283
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.

Moving on to step 10:
60 goes into 200 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 2570.2833
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.

The final outcome is 2570.2833, with a leftover of 0.0002.
