We're dividing 52453275 by 691 
The aim is to understand the frequency of 691 in 52453275.

Moving on to step 1:
If we divide 5 by 691, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 691

Step 2:
If we divide 52 by 691, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 691

On to step 3:
691 goes into 524 0 times with a remainder of 524.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 524 and we're left with 524.
Include the next digit (5) from the dividend after 524, then repeat: 5245 / 691

Advancing to step 4:
691 goes into 5245 7 times with a remainder of 408.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4837 from 5245 to get 408.
Take the next digit (3) from the dividend and append it to 408, then repeat: 4083 / 691

Step 5:
The number 691 fits into 4083 5 times, leaving a remainder of 628.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 628 after subtracting 3455 from 4083.
Append the next digit (2) from the dividend to 628 and continue with: 6282 / 691

Moving on to step 6:
When dividing 6282 by 691, we get 9 with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 759.0
If we subtract 6219 from 6282, we get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 691

Advancing to step 7:
When dividing 637 by 691, we get 0 with a remainder of 637.
The number 0 becomes the next digit in our result. 
Result so far: 7590.0
If we subtract 0 from 637, we get 637.
Take the next digit (5) from the dividend and append it to 637, then repeat: 6375 / 691

Let's proceed to step 8:
6375 divided by 691 is 9 with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 75909.0
Subtracting 6219 from 6375 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 9:
The number 691 fits into 1560 2 times, leaving a remainder of 178.
The next digit of our result is 2. 
Result so far: 75909.2
Deduct 1382 from 1560 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
691 can be fit into 1780 2 times, resulting in a remainder of 398.
Record the quotient 2 as the next digit in the result. 
Result so far: 75909.22
Deduct 1382 from 1780 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Our division results in 75909.22 with a remaining 0.398.
