We're dividing 397913 by 25 
We want to figure out the number of times 397913 can be divided by 25.

Let's proceed to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 25

On to step 2:
25 can be fit into 39 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 25 from 39 leaves us with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 25

Let's proceed to step 3:
25 can be fit into 147 5 times, resulting in a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 125 from 147 leaves us with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 25

On to step 4:
25 goes into 229 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Deduct 225 from 229 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 25

Let's proceed to step 5:
The number 25 fits into 41 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
Deduct 25 from 41 and we're left with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 25

Advancing to step 6:
25 goes into 163 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 15916.0
Subtract 150 from 163 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 25, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 15916.5
Subtracting 125 from 130 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
25 goes into 50 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 15916.52
Subtract 50 from 50 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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15916.52
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.

Let's proceed to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15916.52
The remainder is 0 after subtracting 0 from 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 quotient of the division is 15916.52, and the remainder is 0.0.
