17610205 divided by 397 
The aim is to understand the frequency of 397 in 17610205.

Advancing to step 1:
If we divide 1 by 397, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 397

Going ahead to step 2:
The number 397 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 397

On to step 3:
If we divide 176 by 397, we get 0 and a remainder of 176.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 176 leaves us with 176.
Append the next digit (1) from the dividend to 176 and continue with: 1761 / 397

Moving on to step 4:
If we divide 1761 by 397, we get 4 and a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1588 away from 1761, we end up with 173.
Append the next digit (0) from the dividend to 173 and continue with: 1730 / 397

Step 5:
The number 397 fits into 1730 4 times, leaving a remainder of 142.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 1588 from 1730 leaves us with 142.
Take the next digit (2) from the dividend and append it to 142, then repeat: 1422 / 397

On to step 6:
The number 397 fits into 1422 3 times, leaving a remainder of 231.
The number 3 becomes the next digit in our result. 
Result so far: 443.0
Subtracting 1191 from 1422 leaves us with 231.
Append the next digit (0) from the dividend to 231 and continue with: 2310 / 397

Going ahead to step 7:
If we divide 2310 by 397, we get 5 and a remainder of 325.
The next digit of our result is 5. 
Result so far: 4435.0
Subtracting 1985 from 2310 leaves us with 325.
Append the next digit (5) from the dividend to 325 and continue with: 3255 / 397

Advancing to step 8:
The number 397 fits into 3255 8 times, leaving a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 44358.0
If we subtract 3176 from 3255, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
When dividing 790 by 397, we get 1 with a remainder of 393.
Record the quotient 1 as the next digit in the result. 
Result so far: 44358.1
The remainder is 393 after subtracting 397 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 10:
397 can be fit into 3930 9 times, resulting in a remainder of 357.
The next digit of our result is 9. 
Result so far: 44358.19
The remainder is 357 after subtracting 3573 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 11:
3570 divided by 397 is 8 with a remainder of 394.
Use 8 as the next digit of our solution. 
Result so far: 44358.198
If we take 3176 away from 3570, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 12:
397 can be fit into 3940 9 times, resulting in a remainder of 367.
The number 9 becomes the next digit in our result. 
Result so far: 44358.1989
The remainder is 367 after subtracting 3573 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 13:
When dividing 3670 by 397, we get 9 with a remainder of 97.
The next digit of our result is 9. 
Result so far: 44358.19899
Subtract 3573 from 3670 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final result is 44358.19899 with a remainder of 9.7e-05.
