We divide 21486560 by 633
The aim is to understand the frequency of 633 in 21486560.

Step 1:
The number 633 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 633

On to step 2:
633 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 633

Advancing to step 3:
214 divided by 633 is 0 with a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 633

Step 4:
If we divide 2148 by 633, we get 3 and a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1899 from 2148 to get 249.
Take the next digit (6) from the dividend and append it to 249, then repeat: 2496 / 633

Advancing to step 5:
633 can be fit into 2496 3 times, resulting in a remainder of 597.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 597 after subtracting 1899 from 2496.
Grab the next digit (5) from the dividend, add it to 597, then carry on: 5975 / 633

Step 6:
633 goes into 5975 9 times with a remainder of 278.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
The remainder is 278 after subtracting 5697 from 5975.
Take the next digit (6) from the dividend and append it to 278, then repeat: 2786 / 633

Let's proceed to step 7:
The number 633 fits into 2786 4 times, leaving a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 3394.0
If we subtract 2532 from 2786, we get 254.
Include the next digit (0) from the dividend after 254, then repeat: 2540 / 633

Moving on to step 8:
When dividing 2540 by 633, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 33944.0
If we subtract 2532 from 2540, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 633, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 33944.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
633 can be fit into 800 1 times, resulting in a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 33944.01
Subtracting 633 from 800 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 11:
If we divide 1670 by 633, we get 2 and a remainder of 404.
The number 2 becomes the next digit in our result. 
Result so far: 33944.012
Subtract 1266 from 1670 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 12:
If we divide 4040 by 633, we get 6 and a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 33944.0126
If we take 3798 away from 4040, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 13:
633 can be fit into 2420 3 times, resulting in a remainder of 521.
The number 3 becomes the next digit in our result. 
Result so far: 33944.01263
Deduct 1899 from 2420 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Let's proceed to step 14:
When dividing 5210 by 633, we get 8 with a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 33944.012638
Deduct 5064 from 5210 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 15:
When dividing 1460 by 633, we get 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 33944.0126382
Subtracting 1266 from 1460 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 16:
1940 divided by 633 is 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 33944.01263823
The remainder is 41 after subtracting 1899 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 33944.01263823 with a remainder of 4.1e-08.
