We look at the division of 3865376 by 735 
The aim is to understand the frequency of 735 in 3865376.

Let's proceed to step 1:
The number 735 fits into 3 0 times, leaving 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 (8) from the dividend, attach it to 3 and continue: 38 / 735

Advancing to step 2:
38 divided by 735 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 735

Advancing to step 3:
735 goes into 386 0 times with a remainder of 386.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Fetch the next digit (5) from the dividend, attach it to 386 and continue: 3865 / 735

Step 4:
735 goes into 3865 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 3675 from 3865 leaves us with 190.
Bring next digit (3) of the dividend behind the 190 and repeat the process: 1903 / 735

Moving on to step 5:
1903 divided by 735 is 2 with a remainder of 433.
The next digit of our result is 2. 
Result so far: 52.0
If we take 1470 away from 1903, we end up with 433.
Include the next digit (7) from the dividend after 433, then repeat: 4337 / 735

Advancing to step 6:
735 goes into 4337 5 times with a remainder of 662.
The next digit of our result is 5. 
Result so far: 525.0
If we take 3675 away from 4337, we end up with 662.
Bring next digit (6) of the dividend behind the 662 and repeat the process: 6626 / 735

Moving on to step 7:
The number 735 fits into 6626 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 5259.0
Subtract 6615 from 6626 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
The number 735 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 5259.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
735 goes into 1100 1 times with a remainder of 365.
The number 1 becomes the next digit in our result. 
Result so far: 5259.01
Subtract 735 from 1100 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
When dividing 3650 by 735, we get 4 with a remainder of 710.
Record the quotient 4 as the next digit in the result. 
Result so far: 5259.014
If we take 2940 away from 3650, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 11:
735 goes into 7100 9 times with a remainder of 485.
Use 9 as the next digit of our solution. 
Result so far: 5259.0149
Subtracting 6615 from 7100 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 12:
If we divide 4850 by 735, we get 6 and a remainder of 440.
The next digit of our result is 6. 
Result so far: 5259.01496
Subtract 4410 from 4850 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
4400 divided by 735 is 5 with a remainder of 725.
Record the quotient 5 as the next digit in the result. 
Result so far: 5259.014965
If we subtract 3675 from 4400, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 14:
When dividing 7250 by 735, we get 9 with a remainder of 635.
Put 9 as the next digit of the answer. 
Result so far: 5259.0149659
The remainder is 635 after subtracting 6615 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 15:
735 goes into 6350 8 times with a remainder of 470.
Write down 8 as next digit of the result. 
Result so far: 5259.01496598
If we subtract 5880 from 6350, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 5259.01496598 with a remainder of 4.7e-07.
