25457961 ÷ 201 
We want to figure out the number of times 25457961 can be divided by 201.

Going ahead to step 1:
If we divide 2 by 201, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 201

Advancing to step 2:
201 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 201

Step 3:
254 divided by 201 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 201 from 254 and we're left with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 201

Let's proceed to step 4:
If we divide 535 by 201, we get 2 and a remainder of 133.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 402 from 535 leaves us with 133.
Fetch the next digit (7) from the dividend, attach it to 133 and continue: 1337 / 201

Advancing to step 5:
201 can be fit into 1337 6 times, resulting in a remainder of 131.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 1206 away from 1337, we end up with 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 201

Let's proceed to step 6:
The number 201 fits into 1319 6 times, leaving a remainder of 113.
Put 6 as the next digit of the answer. 
Result so far: 1266.0
Subtracting 1206 from 1319 leaves us with 113.
Bring next digit (6) of the dividend behind the 113 and repeat the process: 1136 / 201

Going ahead to step 7:
201 goes into 1136 5 times with a remainder of 131.
Use 5 as the next digit of our solution. 
Result so far: 12665.0
Subtract 1005 from 1136 to get 131.
Include the next digit (1) from the dividend after 131, then repeat: 1311 / 201

Moving on to step 8:
1311 divided by 201 is 6 with a remainder of 105.
The number 6 becomes the next digit in our result. 
Result so far: 126656.0
Subtracting 1206 from 1311 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
If we divide 1050 by 201, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 126656.5
Subtracting 1005 from 1050 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 201 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 126656.52
Subtracting 402 from 450 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 201, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 126656.522
If we subtract 402 from 480, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 126656.522 and a remainder of 0.0078.
