6698273 ÷ 25 
The aim is to understand the frequency of 25 in 6698273.

Moving on to step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

On to step 2:
66 divided by 25 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 50 from 66 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 25

Step 3:
25 goes into 169 6 times with a remainder of 19.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 150 from 169 and we're left with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 25

On to step 4:
25 can be fit into 198 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
Subtract 175 from 198 to get 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 25

Advancing to step 5:
The number 25 fits into 232 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 2679.0
If we take 225 away from 232, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 25

Let's proceed to step 6:
When dividing 77 by 25, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 26793.0
Subtract 75 from 77 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 25

Going ahead to step 7:
When dividing 23 by 25, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 267930.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
230 divided by 25 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 267930.9
The remainder is 5 after subtracting 225 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 25, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 267930.92
If we take 50 away from 50, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 267930.92
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 267930.92
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 267930.92, and the remainder is 0.0.
