We divide 81802714 by 397
The aim is to understand the frequency of 397 in 81802714.

Let's proceed to step 1:
The number 397 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 397

Let's proceed to step 2:
397 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 397

On to step 3:
When dividing 818 by 397, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 794 away from 818, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 397

Advancing to step 4:
If we divide 240 by 397, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 240 leaves us with 240.
Take the next digit (2) from the dividend and append it to 240, then repeat: 2402 / 397

Going ahead to step 5:
397 can be fit into 2402 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
Deduct 2382 from 2402 and we're left with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 397

Step 6:
207 divided by 397 is 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 2060.0
Deduct 0 from 207 and we're left with 207.
Include the next digit (1) from the dividend after 207, then repeat: 2071 / 397

Moving on to step 7:
2071 divided by 397 is 5 with a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 20605.0
If we subtract 1985 from 2071, we get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 397

Advancing to step 8:
If we divide 864 by 397, we get 2 and a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 206052.0
The remainder is 70 after subtracting 794 from 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
397 can be fit into 700 1 times, resulting in a remainder of 303.
The next digit of our result is 1. 
Result so far: 206052.1
If we take 397 away from 700, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 10:
The number 397 fits into 3030 7 times, leaving a remainder of 251.
Use 7 as the next digit of our solution. 
Result so far: 206052.17
Subtracting 2779 from 3030 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 11:
2510 divided by 397 is 6 with a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 206052.176
If we subtract 2382 from 2510, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
1280 divided by 397 is 3 with a remainder of 89.
The next digit of our result is 3. 
Result so far: 206052.1763
Subtracting 1191 from 1280 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 13:
890 divided by 397 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 206052.17632
Deduct 794 from 890 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
The number 397 fits into 960 2 times, leaving a remainder of 166.
The next digit of our result is 2. 
Result so far: 206052.176322
If we take 794 away from 960, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

After the division, we end up with 206052.176322 and a remainder of 1.66e-05.
