28248121 ÷ 963 
The aim is to understand the frequency of 963 in 28248121.

Let's proceed to step 1:
The number 963 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 963

Let's proceed to step 2:
If we divide 28 by 963, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 963

Let's proceed to step 3:
When dividing 282 by 963, we get 0 with a remainder of 282.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 282 and we're left with 282.
Fetch the next digit (4) from the dividend, attach it to 282 and continue: 2824 / 963

Step 4:
If we divide 2824 by 963, we get 2 and a remainder of 898.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1926 away from 2824, we end up with 898.
Append the next digit (8) from the dividend to 898 and continue with: 8988 / 963

On to step 5:
963 goes into 8988 9 times with a remainder of 321.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 8667 from 8988 leaves us with 321.
Append the next digit (1) from the dividend to 321 and continue with: 3211 / 963

Step 6:
963 goes into 3211 3 times with a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 293.0
If we take 2889 away from 3211, we end up with 322.
Fetch the next digit (2) from the dividend, attach it to 322 and continue: 3222 / 963

Moving on to step 7:
The number 963 fits into 3222 3 times, leaving a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 2933.0
If we subtract 2889 from 3222, we get 333.
Append the next digit (1) from the dividend to 333 and continue with: 3331 / 963

Let's proceed to step 8:
The number 963 fits into 3331 3 times, leaving a remainder of 442.
Use 3 as the next digit of our solution. 
Result so far: 29333.0
Subtracting 2889 from 3331 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 9:
963 can be fit into 4420 4 times, resulting in a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 29333.4
Subtract 3852 from 4420 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
963 goes into 5680 5 times with a remainder of 865.
Put 5 as the next digit of the answer. 
Result so far: 29333.45
If we subtract 4815 from 5680, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

On to step 11:
8650 divided by 963 is 8 with a remainder of 946.
Use 8 as the next digit of our solution. 
Result so far: 29333.458
The remainder is 946 after subtracting 7704 from 8650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9460, and continue the process.

Moving on to step 12:
When dividing 9460 by 963, we get 9 with a remainder of 793.
Write down 9 as next digit of the result. 
Result so far: 29333.4589
Subtract 8667 from 9460 to get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

On to step 13:
When dividing 7930 by 963, we get 8 with a remainder of 226.
Write down 8 as next digit of the result. 
Result so far: 29333.45898
Subtracting 7704 from 7930 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 14:
When dividing 2260 by 963, we get 2 with a remainder of 334.
Put 2 as the next digit of the answer. 
Result so far: 29333.458982
The remainder is 334 after subtracting 1926 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 15:
963 can be fit into 3340 3 times, resulting in a remainder of 451.
Write down 3 as next digit of the result. 
Result so far: 29333.4589823
Subtract 2889 from 3340 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 16:
When dividing 4510 by 963, we get 4 with a remainder of 658.
Put 4 as the next digit of the answer. 
Result so far: 29333.45898234
The remainder is 658 after subtracting 3852 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The final outcome is 29333.45898234, with a leftover of 6.58e-07.
