Let's divide 29903697 by 691
The aim is to understand the frequency of 691 in 29903697.

On to step 1:
2 divided by 691 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 691

On to step 2:
When dividing 29 by 691, we get 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 691

Let's proceed to step 3:
If we divide 299 by 691, we get 0 and a remainder of 299.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 299, we get 299.
Take the next digit (0) from the dividend and append it to 299, then repeat: 2990 / 691

Going ahead to step 4:
691 goes into 2990 4 times with a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2764 away from 2990, we end up with 226.
Bring next digit (3) of the dividend behind the 226 and repeat the process: 2263 / 691

On to step 5:
When dividing 2263 by 691, we get 3 with a remainder of 190.
The next digit of our result is 3. 
Result so far: 43.0
If we take 2073 away from 2263, we end up with 190.
Append the next digit (6) from the dividend to 190 and continue with: 1906 / 691

Let's proceed to step 6:
1906 divided by 691 is 2 with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 432.0
If we subtract 1382 from 1906, we get 524.
Append the next digit (9) from the dividend to 524 and continue with: 5249 / 691

Let's proceed to step 7:
The number 691 fits into 5249 7 times, leaving a remainder of 412.
Write down 7 as next digit of the result. 
Result so far: 4327.0
If we take 4837 away from 5249, we end up with 412.
Fetch the next digit (7) from the dividend, attach it to 412 and continue: 4127 / 691

Step 8:
The number 691 fits into 4127 5 times, leaving a remainder of 672.
Write down 5 as next digit of the result. 
Result so far: 43275.0
If we take 3455 away from 4127, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 9:
691 can be fit into 6720 9 times, resulting in a remainder of 501.
The next digit of our result is 9. 
Result so far: 43275.9
If we subtract 6219 from 6720, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Let's proceed to step 10:
691 can be fit into 5010 7 times, resulting in a remainder of 173.
Put 7 as the next digit of the answer. 
Result so far: 43275.97
Subtracting 4837 from 5010 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
1730 divided by 691 is 2 with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 43275.972
If we subtract 1382 from 1730, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 12:
When dividing 3480 by 691, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 43275.9725
If we subtract 3455 from 3480, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
If we divide 250 by 691, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 43275.9725
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
The number 691 fits into 2500 3 times, leaving a remainder of 427.
Write down 3 as next digit of the result. 
Result so far: 43275.972503
If we subtract 2073 from 2500, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 15:
691 goes into 4270 6 times with a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 43275.9725036
Subtracting 4146 from 4270 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 16:
When dividing 1240 by 691, we get 1 with a remainder of 549.
Write down 1 as next digit of the result. 
Result so far: 43275.97250361
If we subtract 691 from 1240, we 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.

The final result is 43275.97250361 with a remainder of 5.49e-07.
