We look at the division of 991610 by 25 
We want to divide 991610 by 25.

Advancing to step 1:
If we divide 9 by 25, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 25

Moving on to step 2:
99 divided by 25 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 75 from 99 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 25

Moving on to step 3:
25 can be fit into 241 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 225 away from 241, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 25

Going ahead to step 4:
25 can be fit into 166 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 396.0
If we take 150 away from 166, we end up with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 25

Step 5:
When dividing 161 by 25, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 3966.0
Subtracting 150 from 161 leaves us with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 25

Going ahead to step 6:
25 goes into 110 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 39664.0
If we take 100 away from 110, we end up 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.

Step 7:
When dividing 100 by 25, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 39664.4
Deduct 100 from 100 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 8:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39664.4
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.

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: 39664.4
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.

Our division results in 39664.4 with a remaining 0.0.
