Let's divide 251902 by 60
We want to figure out the number of times 251902 can be divided by 60.

Advancing to step 1:
2 divided by 60 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 60

Going ahead to step 2:
60 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 60

Moving on to step 3:
If we divide 251 by 60, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 240 from 251 leaves us with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 60

Moving on to step 4:
60 can be fit into 119 1 times, resulting in a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 60 away from 119, we end up with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 60

Advancing to step 5:
The number 60 fits into 590 9 times, leaving a remainder of 50.
The next digit of our result is 9. 
Result so far: 419.0
Subtracting 540 from 590 leaves us with 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 60

On to step 6:
If we divide 502 by 60, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 4198.0
Subtract 480 from 502 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 60, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 4198.3
If we take 180 away from 220, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
60 goes into 400 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4198.36
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 60 fits into 400 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4198.366
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 4198.366 with a remainder of 0.004.
