We look at the division of 25499600 by 60 
We want to figure out the number of times 25499600 can be divided by 60.

Let's proceed to step 1:
When dividing 2 by 60, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 60

Step 2:
60 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 60

Going ahead to step 3:
60 goes into 254 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 240 from 254 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 60

Step 4:
149 divided by 60 is 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 120 from 149 leaves us with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 60

On to step 5:
60 goes into 299 4 times with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
The remainder is 59 after subtracting 240 from 299.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 60

On to step 6:
596 divided by 60 is 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 4249.0
Deduct 540 from 596 and we're left with 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 60

Let's proceed to step 7:
If we divide 560 by 60, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 42499.0
Deduct 540 from 560 and we're left with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 60

Let's proceed to step 8:
60 goes into 200 3 times with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 424993.0
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 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 424993.3
Subtracting 180 from 200 leaves us 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.

Moving on to step 10:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 424993.33
Deduct 180 from 200 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.

The final outcome is 424993.33, with a leftover of 0.02.
