53228729 divided by 60 
The aim is to understand the frequency of 60 in 53228729.

On to step 1:
When dividing 5 by 60, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 60

Moving on to step 2:
If we divide 53 by 60, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 60

Step 3:
The number 60 fits into 532 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 480 from 532 to get 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 60

Advancing to step 4:
522 divided by 60 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 480 from 522 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 60

Moving on to step 5:
When dividing 428 by 60, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
Deduct 420 from 428 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 60

Advancing to step 6:
The number 60 fits into 87 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 8871.0
If we take 60 away from 87, we end up with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 60

Advancing to step 7:
When dividing 272 by 60, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 88714.0
The remainder is 32 after subtracting 240 from 272.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 60

Step 8:
60 goes into 329 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 887145.0
If we subtract 300 from 329, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
60 goes into 290 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 887145.4
Subtract 240 from 290 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 60 fits into 500 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 887145.48
Subtract 480 from 500 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.

Step 11:
60 goes into 200 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 887145.483
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.

Let's proceed to step 12:
200 divided by 60 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 887145.4833
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 result is 887145.4833 with a remainder of 0.0002.
