We look at the division of 25707969 by 633 
The aim is to understand the frequency of 633 in 25707969.

Advancing to step 1:
If we divide 2 by 633, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 633

Moving on to step 2:
25 divided by 633 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 633

Moving on to step 3:
633 goes into 257 0 times with a remainder of 257.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 257 and we're left with 257.
Take the next digit (0) from the dividend and append it to 257, then repeat: 2570 / 633

Let's proceed to step 4:
633 goes into 2570 4 times with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2532 from 2570, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 633

On to step 5:
633 goes into 387 0 times with a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 387 to get 387.
Bring next digit (9) of the dividend behind the 387 and repeat the process: 3879 / 633

Going ahead to step 6:
The number 633 fits into 3879 6 times, leaving a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
Subtracting 3798 from 3879 leaves us with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 633

Moving on to step 7:
The number 633 fits into 816 1 times, leaving a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 4061.0
Subtract 633 from 816 to get 183.
Grab the next digit (9) from the dividend, add it to 183, then carry on: 1839 / 633

Let's proceed to step 8:
633 can be fit into 1839 2 times, resulting in a remainder of 573.
Use 2 as the next digit of our solution. 
Result so far: 40612.0
Deduct 1266 from 1839 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 9:
633 can be fit into 5730 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 40612.9
Deduct 5697 from 5730 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
633 can be fit into 330 0 times, resulting in a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 40612.9
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
The number 633 fits into 3300 5 times, leaving a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 40612.905
If we take 3165 away from 3300, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 12:
The number 633 fits into 1350 2 times, leaving a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 40612.9052
The remainder is 84 after subtracting 1266 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
840 divided by 633 is 1 with a remainder of 207.
The next digit of our result is 1. 
Result so far: 40612.90521
Deduct 633 from 840 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 14:
2070 divided by 633 is 3 with a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 40612.905213
If we take 1899 away from 2070, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 15:
When dividing 1710 by 633, we get 2 with a remainder of 444.
Record the quotient 2 as the next digit in the result. 
Result so far: 40612.9052132
Subtract 1266 from 1710 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 16:
If we divide 4440 by 633, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 40612.90521327
The remainder is 9 after subtracting 4431 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 40612.90521327 with a remainder of 9e-09.
