50403918 ÷ 60 
The aim is to understand the frequency of 60 in 50403918.

Going ahead to step 1:
When dividing 5 by 60, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 60

Moving on to step 2:
60 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 60

On to step 3:
When dividing 504 by 60, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 24 after subtracting 480 from 504.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 60

On to step 4:
240 divided by 60 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtract 240 from 240 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 60

Advancing to step 5:
The number 60 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 840.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 60

Moving on to step 6:
60 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 8400.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 60

Going ahead to step 7:
The number 60 fits into 391 6 times, leaving a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 84006.0
Subtracting 360 from 391 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 60

Moving on to step 8:
60 can be fit into 318 5 times, resulting in a remainder of 18.
The next digit of our result is 5. 
Result so far: 840065.0
The remainder is 18 after subtracting 300 from 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
If we divide 180 by 60, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 840065.3
If we take 180 away from 180, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
60 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 840065.3
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.

Let's proceed to step 11:
When dividing 0 by 60, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 840065.3
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.

In conclusion, the division gives 840065.3 with a balance of 0.0.
