25188409 ÷ 981 
The aim is to understand the frequency of 981 in 25188409.

Let's proceed to step 1:
The number 981 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 981

Advancing to step 2:
The number 981 fits into 25 0 times, leaving 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 (1) from the dividend, add it to 25, then carry on: 251 / 981

Let's proceed to step 3:
If we divide 251 by 981, we get 0 and a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Grab the next digit (8) from the dividend, add it to 251, then carry on: 2518 / 981

On to step 4:
981 goes into 2518 2 times with a remainder of 556.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 556 after subtracting 1962 from 2518.
Bring next digit (8) of the dividend behind the 556 and repeat the process: 5568 / 981

On to step 5:
The number 981 fits into 5568 5 times, leaving a remainder of 663.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 4905 from 5568 and we're left with 663.
Take the next digit (4) from the dividend and append it to 663, then repeat: 6634 / 981

On to step 6:
When dividing 6634 by 981, we get 6 with a remainder of 748.
Write down 6 as next digit of the result. 
Result so far: 256.0
The remainder is 748 after subtracting 5886 from 6634.
Include the next digit (0) from the dividend after 748, then repeat: 7480 / 981

Let's proceed to step 7:
981 can be fit into 7480 7 times, resulting in a remainder of 613.
Use 7 as the next digit of our solution. 
Result so far: 2567.0
Subtracting 6867 from 7480 leaves us with 613.
Include the next digit (9) from the dividend after 613, then repeat: 6139 / 981

Moving on to step 8:
If we divide 6139 by 981, we get 6 and a remainder of 253.
Use 6 as the next digit of our solution. 
Result so far: 25676.0
Deduct 5886 from 6139 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
The number 981 fits into 2530 2 times, leaving a remainder of 568.
Record the quotient 2 as the next digit in the result. 
Result so far: 25676.2
Subtract 1962 from 2530 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
5680 divided by 981 is 5 with a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 25676.25
The remainder is 775 after subtracting 4905 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Going ahead to step 11:
When dividing 7750 by 981, we get 7 with a remainder of 883.
The number 7 becomes the next digit in our result. 
Result so far: 25676.257
Deduct 6867 from 7750 and we're left with 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Advancing to step 12:
981 can be fit into 8830 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 25676.2579
If we take 8829 away from 8830, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
When dividing 10 by 981, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25676.2579
Subtract 0 from 10 to get 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 14:
981 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 25676.2579
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 25676.2579, and the remainder is 1e-05.
