We're dividing 15487241 by 691 
The aim is to understand the frequency of 691 in 15487241.

Advancing to step 1:
The number 691 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 691

Let's proceed to step 2:
If we divide 15 by 691, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 691

On to step 3:
If we divide 154 by 691, we get 0 and a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Bring next digit (8) of the dividend behind the 154 and repeat the process: 1548 / 691

Step 4:
The number 691 fits into 1548 2 times, leaving a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1382 from 1548 and we're left with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 691

Step 5:
The number 691 fits into 1667 2 times, leaving a remainder of 285.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 1382 away from 1667, we end up with 285.
Include the next digit (2) from the dividend after 285, then repeat: 2852 / 691

Let's proceed to step 6:
The number 691 fits into 2852 4 times, leaving a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 224.0
The remainder is 88 after subtracting 2764 from 2852.
Include the next digit (4) from the dividend after 88, then repeat: 884 / 691

Advancing to step 7:
691 can be fit into 884 1 times, resulting in a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 2241.0
The remainder is 193 after subtracting 691 from 884.
Fetch the next digit (1) from the dividend, attach it to 193 and continue: 1931 / 691

Let's proceed to step 8:
1931 divided by 691 is 2 with a remainder of 549.
The number 2 becomes the next digit in our result. 
Result so far: 22412.0
Subtract 1382 from 1931 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 9:
691 can be fit into 5490 7 times, resulting in a remainder of 653.
Put 7 as the next digit of the answer. 
Result so far: 22412.7
If we take 4837 away from 5490, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 10:
691 can be fit into 6530 9 times, resulting in a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 22412.79
If we subtract 6219 from 6530, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 11:
3110 divided by 691 is 4 with a remainder of 346.
Record the quotient 4 as the next digit in the result. 
Result so far: 22412.794
If we take 2764 away from 3110, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 12:
691 can be fit into 3460 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 22412.7945
The remainder is 5 after subtracting 3455 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 691 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 22412.7945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
691 can be fit into 500 0 times, resulting in a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 22412.7945
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 22412.7945, with a leftover of 5e-05.
