We look at the division of 25356574 by 147 
The aim is to understand the frequency of 147 in 25356574.

Step 1:
2 divided by 147 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 147

Going ahead to step 2:
147 can be fit into 25 0 times, resulting in 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.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 147

Going ahead to step 3:
If we divide 253 by 147, we get 1 and a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 147 from 253 to get 106.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 147

Step 4:
When dividing 1065 by 147, we get 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 1029 from 1065 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 147

On to step 5:
147 can be fit into 366 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Deduct 294 from 366 and we're left with 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 147

On to step 6:
If we divide 725 by 147, we get 4 and a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 1724.0
The remainder is 137 after subtracting 588 from 725.
Grab the next digit (7) from the dividend, add it to 137, then carry on: 1377 / 147

Step 7:
147 goes into 1377 9 times with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 17249.0
If we take 1323 away from 1377, we end up with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 147

On to step 8:
147 goes into 544 3 times with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 172493.0
If we subtract 441 from 544, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
When dividing 1030 by 147, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 172493.7
Deduct 1029 from 1030 and we're left 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.

Let's proceed to step 10:
When dividing 10 by 147, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 172493.7
Deduct 0 from 10 and we're left 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.

Let's proceed to step 11:
147 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 172493.7
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 final outcome is 172493.7, with a leftover of 0.01.
