We look at the division of 3042336 by 640 
The aim is to understand the frequency of 640 in 3042336.

Going ahead to step 1:
640 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 640

Going ahead to step 2:
If we divide 30 by 640, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 640

Advancing to step 3:
640 goes into 304 0 times with a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Take the next digit (2) from the dividend and append it to 304, then repeat: 3042 / 640

Advancing to step 4:
When dividing 3042 by 640, we get 4 with a remainder of 482.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 2560 from 3042 leaves us with 482.
Take the next digit (3) from the dividend and append it to 482, then repeat: 4823 / 640

Let's proceed to step 5:
The number 640 fits into 4823 7 times, leaving a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 4480 from 4823, we get 343.
Include the next digit (3) from the dividend after 343, then repeat: 3433 / 640

Going ahead to step 6:
The number 640 fits into 3433 5 times, leaving a remainder of 233.
Use 5 as the next digit of our solution. 
Result so far: 475.0
If we subtract 3200 from 3433, we get 233.
Fetch the next digit (6) from the dividend, attach it to 233 and continue: 2336 / 640

Step 7:
When dividing 2336 by 640, we get 3 with a remainder of 416.
Put 3 as the next digit of the answer. 
Result so far: 4753.0
If we subtract 1920 from 2336, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 8:
If we divide 4160 by 640, we get 6 and a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 4753.6
If we take 3840 away from 4160, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 9:
640 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4753.65
The remainder is 0 after subtracting 3200 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4753.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
640 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4753.65
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4753.65 with a remainder of 0.0.
