We're dividing 30217507 by 397 
The aim is to understand the frequency of 397 in 30217507.

Going ahead to step 1:
397 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 397

Moving on to step 2:
When dividing 30 by 397, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 397

Going ahead to step 3:
If we divide 302 by 397, we get 0 and a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 302, we end up with 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 397

Step 4:
3021 divided by 397 is 7 with a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 2779 from 3021 to get 242.
Fetch the next digit (7) from the dividend, attach it to 242 and continue: 2427 / 397

Let's proceed to step 5:
2427 divided by 397 is 6 with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 2382 from 2427 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 397

Step 6:
397 can be fit into 455 1 times, resulting in a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we take 397 away from 455, we end up with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 397

Step 7:
If we divide 580 by 397, we get 1 and a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 7611.0
The remainder is 183 after subtracting 397 from 580.
Append the next digit (7) from the dividend to 183 and continue with: 1837 / 397

Going ahead to step 8:
1837 divided by 397 is 4 with a remainder of 249.
Write down 4 as next digit of the result. 
Result so far: 76114.0
If we subtract 1588 from 1837, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 9:
397 can be fit into 2490 6 times, resulting in a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 76114.6
If we subtract 2382 from 2490, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
When dividing 1080 by 397, we get 2 with a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 76114.62
Subtract 794 from 1080 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 11:
397 goes into 2860 7 times with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 76114.627
Subtract 2779 from 2860 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
When dividing 810 by 397, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 76114.6272
If we subtract 794 from 810, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
397 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 76114.6272
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 397, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 76114.627204
If we subtract 1588 from 1600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
397 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 76114.627204
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
397 goes into 1200 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 76114.62720403
If we take 1191 away from 1200, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 76114.62720403 with a balance of 9e-09.
