210450 ÷ 60 
The aim is to understand the frequency of 60 in 210450.

Step 1:
If we divide 2 by 60, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 60

Advancing to step 2:
The number 60 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 60

Moving on to step 3:
60 goes into 210 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 180 from 210, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 60

Advancing to step 4:
60 can be fit into 304 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 300 from 304, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 60

Step 5:
When dividing 45 by 60, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we take 0 away from 45, we end up with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 60

On to step 6:
60 can be fit into 450 7 times, resulting in a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 3507.0
The remainder is 30 after subtracting 420 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 60 fits into 300 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3507.5
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.

Step 8:
When dividing 0 by 60, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3507.5
Subtract 0 from 0 to 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.

Going ahead to step 9:
When dividing 0 by 60, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3507.5
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.

In conclusion, the division gives 3507.5 with a balance of 0.0.
