We're dividing 28303383 by 959 
The aim is to understand the frequency of 959 in 28303383.

Step 1:
The number 959 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 959

Step 2:
28 divided by 959 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 959

Going ahead to step 3:
283 divided by 959 is 0 with a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 283 and we're left with 283.
Take the next digit (0) from the dividend and append it to 283, then repeat: 2830 / 959

Going ahead to step 4:
959 goes into 2830 2 times with a remainder of 912.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1918 from 2830 and we're left with 912.
Bring next digit (3) of the dividend behind the 912 and repeat the process: 9123 / 959

Advancing to step 5:
When dividing 9123 by 959, we get 9 with a remainder of 492.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 8631 from 9123 to get 492.
Fetch the next digit (3) from the dividend, attach it to 492 and continue: 4923 / 959

Going ahead to step 6:
959 goes into 4923 5 times with a remainder of 128.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Deduct 4795 from 4923 and we're left with 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 959

Going ahead to step 7:
When dividing 1288 by 959, we get 1 with a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 2951.0
Subtract 959 from 1288 to get 329.
Bring next digit (3) of the dividend behind the 329 and repeat the process: 3293 / 959

Let's proceed to step 8:
959 can be fit into 3293 3 times, resulting in a remainder of 416.
The next digit of our result is 3. 
Result so far: 29513.0
If we take 2877 away from 3293, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
The number 959 fits into 4160 4 times, leaving a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 29513.4
Deduct 3836 from 4160 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 10:
959 goes into 3240 3 times with a remainder of 363.
The next digit of our result is 3. 
Result so far: 29513.43
Deduct 2877 from 3240 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 11:
If we divide 3630 by 959, we get 3 and a remainder of 753.
Write down 3 as next digit of the result. 
Result so far: 29513.433
Subtracting 2877 from 3630 leaves us with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

In conclusion, the division gives 29513.433 with a balance of 0.0753.
