65707036 ÷ 397 
The aim is to understand the frequency of 397 in 65707036.

Moving on to step 1:
If we divide 6 by 397, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 397

On to step 2:
If we divide 65 by 397, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 397

Moving on to step 3:
397 goes into 657 1 times with a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 397 from 657 to get 260.
Append the next digit (0) from the dividend to 260 and continue with: 2600 / 397

Going ahead to step 4:
2600 divided by 397 is 6 with a remainder of 218.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 2382 from 2600, we get 218.
Grab the next digit (7) from the dividend, add it to 218, then carry on: 2187 / 397

Step 5:
When dividing 2187 by 397, we get 5 with a remainder of 202.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 1985 from 2187 and we're left with 202.
Append the next digit (0) from the dividend to 202 and continue with: 2020 / 397

Going ahead to step 6:
397 goes into 2020 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1655.0
Deduct 1985 from 2020 and we're left with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 397

On to step 7:
When dividing 353 by 397, we get 0 with a remainder of 353.
The number 0 becomes the next digit in our result. 
Result so far: 16550.0
Subtracting 0 from 353 leaves us with 353.
Fetch the next digit (6) from the dividend, attach it to 353 and continue: 3536 / 397

Step 8:
397 can be fit into 3536 8 times, resulting in a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 165508.0
Deduct 3176 from 3536 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
397 can be fit into 3600 9 times, resulting in a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 165508.9
If we take 3573 away from 3600, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
397 goes into 270 0 times with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 165508.9
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
397 can be fit into 2700 6 times, resulting in a remainder of 318.
The next digit of our result is 6. 
Result so far: 165508.906
If we subtract 2382 from 2700, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 12:
When dividing 3180 by 397, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 165508.9068
If we take 3176 away from 3180, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 397 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 165508.9068
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
When dividing 400 by 397, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 165508.906801
Subtracting 397 from 400 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
30 divided by 397 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 165508.906801
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
When dividing 300 by 397, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 165508.906801
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 165508.906801 with a remainder of 3e-07.
