We're dividing 25481107 by 73 
The aim is to understand the frequency of 73 in 25481107.

Step 1:
When dividing 2 by 73, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 73

Advancing to step 2:
73 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 73

On to step 3:
The number 73 fits into 254 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 219 from 254 and we're left with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 73

Advancing to step 4:
358 divided by 73 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 292 away from 358, we end up with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 73

On to step 5:
When dividing 661 by 73, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 349.0
Subtract 657 from 661 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 73

Step 6:
73 goes into 41 0 times with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 3490.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 73

Going ahead to step 7:
410 divided by 73 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 34905.0
If we take 365 away from 410, we end up with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 73

Moving on to step 8:
73 can be fit into 457 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 349056.0
Deduct 438 from 457 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
If we divide 190 by 73, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 349056.2
Deduct 146 from 190 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
The number 73 fits into 440 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 349056.26
Deduct 438 from 440 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 73, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 349056.26
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
200 divided by 73 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 349056.2602
Subtracting 146 from 200 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 73 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 349056.26027
If we subtract 511 from 540, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
If we divide 290 by 73, we get 3 and a remainder of 71.
The next digit of our result is 3. 
Result so far: 349056.260273
If we subtract 219 from 290, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 15:
When dividing 710 by 73, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 349056.2602739
If we take 657 away from 710, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 16:
When dividing 530 by 73, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 349056.26027397
The remainder is 19 after subtracting 511 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 349056.26027397, and the remainder is 1.9e-08.
