65378839 ÷ 935 
The aim is to understand the frequency of 935 in 65378839.

Let's proceed to step 1:
If we divide 6 by 935, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 935

Let's proceed to step 2:
935 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 935

Going ahead to step 3:
The number 935 fits into 653 0 times, leaving a remainder of 653.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 653 leaves us with 653.
Fetch the next digit (7) from the dividend, attach it to 653 and continue: 6537 / 935

Moving on to step 4:
935 can be fit into 6537 6 times, resulting in a remainder of 927.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5610 from 6537 leaves us with 927.
Include the next digit (8) from the dividend after 927, then repeat: 9278 / 935

Advancing to step 5:
The number 935 fits into 9278 9 times, leaving a remainder of 863.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 8415 from 9278 leaves us with 863.
Include the next digit (8) from the dividend after 863, then repeat: 8638 / 935

Step 6:
8638 divided by 935 is 9 with a remainder of 223.
Record the quotient 9 as the next digit in the result. 
Result so far: 699.0
Subtract 8415 from 8638 to get 223.
Take the next digit (3) from the dividend and append it to 223, then repeat: 2233 / 935

Going ahead to step 7:
When dividing 2233 by 935, we get 2 with a remainder of 363.
The number 2 becomes the next digit in our result. 
Result so far: 6992.0
The remainder is 363 after subtracting 1870 from 2233.
Fetch the next digit (9) from the dividend, attach it to 363 and continue: 3639 / 935

On to step 8:
The number 935 fits into 3639 3 times, leaving a remainder of 834.
The number 3 becomes the next digit in our result. 
Result so far: 69923.0
If we subtract 2805 from 3639, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Step 9:
When dividing 8340 by 935, we get 8 with a remainder of 860.
Record the quotient 8 as the next digit in the result. 
Result so far: 69923.8
If we take 7480 away from 8340, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 10:
If we divide 8600 by 935, we get 9 and a remainder of 185.
Use 9 as the next digit of our solution. 
Result so far: 69923.89
Subtracting 8415 from 8600 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
1850 divided by 935 is 1 with a remainder of 915.
The next digit of our result is 1. 
Result so far: 69923.891
Subtracting 935 from 1850 leaves us with 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

On to step 12:
When dividing 9150 by 935, we get 9 with a remainder of 735.
Record the quotient 9 as the next digit in the result. 
Result so far: 69923.8919
Deduct 8415 from 9150 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Going ahead to step 13:
If we divide 7350 by 935, we get 7 and a remainder of 805.
Write down 7 as next digit of the result. 
Result so far: 69923.89197
Subtract 6545 from 7350 to get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Going ahead to step 14:
935 can be fit into 8050 8 times, resulting in a remainder of 570.
The number 8 becomes the next digit in our result. 
Result so far: 69923.891978
Subtracting 7480 from 8050 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 15:
The number 935 fits into 5700 6 times, leaving a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 69923.8919786
If we subtract 5610 from 5700, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
If we divide 900 by 935, we get 0 and a remainder of 900.
Put 0 as the next digit of the answer. 
Result so far: 69923.8919786
If we subtract 0 from 900, we get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

The final outcome is 69923.8919786, with a leftover of 9e-07.
