We look at the division of 5169505 by 691 
The aim is to understand the frequency of 691 in 5169505.

On to step 1:
691 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 691

Step 2:
691 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 691

Going ahead to step 3:
The number 691 fits into 516 0 times, leaving a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Bring next digit (9) of the dividend behind the 516 and repeat the process: 5169 / 691

Let's proceed to step 4:
691 goes into 5169 7 times with a remainder of 332.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4837 from 5169 and we're left with 332.
Fetch the next digit (5) from the dividend, attach it to 332 and continue: 3325 / 691

Moving on to step 5:
When dividing 3325 by 691, we get 4 with a remainder of 561.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 2764 from 3325, we get 561.
Fetch the next digit (0) from the dividend, attach it to 561 and continue: 5610 / 691

On to step 6:
5610 divided by 691 is 8 with a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 748.0
Subtracting 5528 from 5610 leaves us with 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 691

Advancing to step 7:
691 goes into 825 1 times with a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 7481.0
The remainder is 134 after subtracting 691 from 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 8:
If we divide 1340 by 691, we get 1 and a remainder of 649.
The number 1 becomes the next digit in our result. 
Result so far: 7481.1
Subtracting 691 from 1340 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Going ahead to step 9:
The number 691 fits into 6490 9 times, leaving a remainder of 271.
The number 9 becomes the next digit in our result. 
Result so far: 7481.19
If we take 6219 away from 6490, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 10:
691 can be fit into 2710 3 times, resulting in a remainder of 637.
Put 3 as the next digit of the answer. 
Result so far: 7481.193
Subtract 2073 from 2710 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 11:
If we divide 6370 by 691, we get 9 and a remainder of 151.
The next digit of our result is 9. 
Result so far: 7481.1939
If we take 6219 away from 6370, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 12:
691 can be fit into 1510 2 times, resulting in a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 7481.19392
Subtracting 1382 from 1510 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
The number 691 fits into 1280 1 times, leaving a remainder of 589.
Put 1 as the next digit of the answer. 
Result so far: 7481.193921
The remainder is 589 after subtracting 691 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Moving on to step 14:
The number 691 fits into 5890 8 times, leaving a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 7481.1939218
The remainder is 362 after subtracting 5528 from 5890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 15:
The number 691 fits into 3620 5 times, leaving a remainder of 165.
The next digit of our result is 5. 
Result so far: 7481.19392185
If we subtract 3455 from 3620, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 7481.19392185, and the remainder is 1.65e-07.
