We look at the division of 49603904 by 960 
The aim is to understand the frequency of 960 in 49603904.

Going ahead to step 1:
When dividing 4 by 960, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 960

Going ahead to step 2:
When dividing 49 by 960, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 960

Going ahead to step 3:
The number 960 fits into 496 0 times, leaving a remainder of 496.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 496, we get 496.
Include the next digit (0) from the dividend after 496, then repeat: 4960 / 960

Moving on to step 4:
When dividing 4960 by 960, we get 5 with a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4800 away from 4960, we end up with 160.
Fetch the next digit (3) from the dividend, attach it to 160 and continue: 1603 / 960

Moving on to step 5:
1603 divided by 960 is 1 with a remainder of 643.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 960 from 1603 and we're left with 643.
Grab the next digit (9) from the dividend, add it to 643, then carry on: 6439 / 960

Moving on to step 6:
If we divide 6439 by 960, we get 6 and a remainder of 679.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
Subtracting 5760 from 6439 leaves us with 679.
Include the next digit (0) from the dividend after 679, then repeat: 6790 / 960

On to step 7:
When dividing 6790 by 960, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 5167.0
Deduct 6720 from 6790 and we're left with 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 960

Going ahead to step 8:
704 divided by 960 is 0 with a remainder of 704.
Write down 0 as next digit of the result. 
Result so far: 51670.0
If we take 0 away from 704, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 9:
If we divide 7040 by 960, we get 7 and a remainder of 320.
The next digit of our result is 7. 
Result so far: 51670.7
The remainder is 320 after subtracting 6720 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
The number 960 fits into 3200 3 times, leaving a remainder of 320.
Write down 3 as next digit of the result. 
Result so far: 51670.73
If we subtract 2880 from 3200, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
960 goes into 3200 3 times with a remainder of 320.
The next digit of our result is 3. 
Result so far: 51670.733
Deduct 2880 from 3200 and we're left 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.

Our division results in 51670.733 with a remaining 0.032.
