We divide 615491 by 25
We're looking to find how many times 25 goes into 615491.

Advancing to step 1:
If we divide 6 by 25, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 25

Let's proceed to step 2:
If we divide 61 by 25, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 50 away from 61, we end up with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 25

Moving on to step 3:
If we divide 115 by 25, we get 4 and a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 100 from 115, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 25

Advancing to step 4:
25 goes into 154 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 246.0
The remainder is 4 after subtracting 150 from 154.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 25

Advancing to step 5:
25 can be fit into 49 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 2461.0
The remainder is 24 after subtracting 25 from 49.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 25

Going ahead to step 6:
If we divide 241 by 25, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 24619.0
If we take 225 away from 241, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 25, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 24619.6
Subtracting 150 from 160 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24619.64
The remainder is 0 after subtracting 100 from 100.
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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24619.64
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 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24619.64
Deduct 0 from 0 and we're left 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.

The final outcome is 24619.64, with a leftover of 0.0.
