We're dividing 53631439 by 960 
The aim is to understand the frequency of 960 in 53631439.

Let's proceed to step 1:
When dividing 5 by 960, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 960

Step 2:
When dividing 53 by 960, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 960

Step 3:
960 goes into 536 0 times with a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 536, we end up with 536.
Take the next digit (3) from the dividend and append it to 536, then repeat: 5363 / 960

Going ahead to step 4:
960 goes into 5363 5 times with a remainder of 563.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4800 away from 5363, we end up with 563.
Fetch the next digit (1) from the dividend, attach it to 563 and continue: 5631 / 960

Going ahead to step 5:
The number 960 fits into 5631 5 times, leaving a remainder of 831.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 4800 from 5631 and we're left with 831.
Take the next digit (4) from the dividend and append it to 831, then repeat: 8314 / 960

On to step 6:
The number 960 fits into 8314 8 times, leaving a remainder of 634.
The next digit of our result is 8. 
Result so far: 558.0
Subtract 7680 from 8314 to get 634.
Append the next digit (3) from the dividend to 634 and continue with: 6343 / 960

Moving on to step 7:
The number 960 fits into 6343 6 times, leaving a remainder of 583.
Use 6 as the next digit of our solution. 
Result so far: 5586.0
If we subtract 5760 from 6343, we get 583.
Bring next digit (9) of the dividend behind the 583 and repeat the process: 5839 / 960

On to step 8:
When dividing 5839 by 960, we get 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 55866.0
If we take 5760 away from 5839, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
The number 960 fits into 790 0 times, leaving a remainder of 790.
The number 0 becomes the next digit in our result. 
Result so far: 55866.0
Subtracting 0 from 790 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
960 can be fit into 7900 8 times, resulting in a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 55866.08
The remainder is 220 after subtracting 7680 from 7900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
The number 960 fits into 2200 2 times, leaving a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 55866.082
Subtract 1920 from 2200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
2800 divided by 960 is 2 with a remainder of 880.
The number 2 becomes the next digit in our result. 
Result so far: 55866.0822
Deduct 1920 from 2800 and we're left with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

In conclusion, the division gives 55866.0822 with a balance of 0.0088.
