25581181 divided by 247 
The aim is to understand the frequency of 247 in 25581181.

Step 1:
The number 247 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 247

On to step 2:
When dividing 25 by 247, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 247

Going ahead to step 3:
When dividing 255 by 247, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 247 from 255 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 247

Advancing to step 4:
The number 247 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 88 to get 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 247

Advancing to step 5:
247 goes into 881 3 times with a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 741 from 881 to get 140.
Take the next digit (1) from the dividend and append it to 140, then repeat: 1401 / 247

Step 6:
1401 divided by 247 is 5 with a remainder of 166.
The next digit of our result is 5. 
Result so far: 1035.0
Subtracting 1235 from 1401 leaves us with 166.
Append the next digit (8) from the dividend to 166 and continue with: 1668 / 247

Advancing to step 7:
When dividing 1668 by 247, we get 6 with a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 10356.0
Deduct 1482 from 1668 and we're left with 186.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 247

Advancing to step 8:
247 goes into 1861 7 times with a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 103567.0
Deduct 1729 from 1861 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
When dividing 1320 by 247, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 103567.5
If we take 1235 away from 1320, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
If we divide 850 by 247, we get 3 and a remainder of 109.
The next digit of our result is 3. 
Result so far: 103567.53
Deduct 741 from 850 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
247 can be fit into 1090 4 times, resulting in a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 103567.534
Subtract 988 from 1090 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
If we divide 1020 by 247, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 103567.5344
Deduct 988 from 1020 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 103567.5344, with a leftover of 0.00032.
