90516928 ÷ 633 
The aim is to understand the frequency of 633 in 90516928.

On to step 1:
The number 633 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 633

Let's proceed to step 2:
633 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 633

Advancing to step 3:
When dividing 905 by 633, we get 1 with a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 633 from 905 to get 272.
Grab the next digit (1) from the dividend, add it to 272, then carry on: 2721 / 633

Advancing to step 4:
If we divide 2721 by 633, we get 4 and a remainder of 189.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2532 from 2721 leaves us with 189.
Bring next digit (6) of the dividend behind the 189 and repeat the process: 1896 / 633

Advancing to step 5:
The number 633 fits into 1896 2 times, leaving a remainder of 630.
The next digit of our result is 2. 
Result so far: 142.0
Subtract 1266 from 1896 to get 630.
Bring next digit (9) of the dividend behind the 630 and repeat the process: 6309 / 633

Let's proceed to step 6:
6309 divided by 633 is 9 with a remainder of 612.
Use 9 as the next digit of our solution. 
Result so far: 1429.0
Deduct 5697 from 6309 and we're left with 612.
Bring next digit (2) of the dividend behind the 612 and repeat the process: 6122 / 633

Going ahead to step 7:
When dividing 6122 by 633, we get 9 with a remainder of 425.
Write down 9 as next digit of the result. 
Result so far: 14299.0
Subtracting 5697 from 6122 leaves us with 425.
Append the next digit (8) from the dividend to 425 and continue with: 4258 / 633

Going ahead to step 8:
633 goes into 4258 6 times with a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 142996.0
Subtracting 3798 from 4258 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 9:
4600 divided by 633 is 7 with a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 142996.7
If we subtract 4431 from 4600, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 10:
1690 divided by 633 is 2 with a remainder of 424.
Use 2 as the next digit of our solution. 
Result so far: 142996.72
Deduct 1266 from 1690 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 11:
633 can be fit into 4240 6 times, resulting in a remainder of 442.
Use 6 as the next digit of our solution. 
Result so far: 142996.726
If we subtract 3798 from 4240, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 12:
4420 divided by 633 is 6 with a remainder of 622.
The number 6 becomes the next digit in our result. 
Result so far: 142996.7266
Subtracting 3798 from 4420 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

After the division, we end up with 142996.7266 and a remainder of 0.00622.
