We're dividing 80669129 by 633 
The aim is to understand the frequency of 633 in 80669129.

Advancing to step 1:
633 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 633

Step 2:
633 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 633

Going ahead to step 3:
If we divide 806 by 633, we get 1 and a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 633 from 806 to get 173.
Include the next digit (6) from the dividend after 173, then repeat: 1736 / 633

Moving on to step 4:
The number 633 fits into 1736 2 times, leaving a remainder of 470.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1266 from 1736 and we're left with 470.
Fetch the next digit (9) from the dividend, attach it to 470 and continue: 4709 / 633

Going ahead to step 5:
633 goes into 4709 7 times with a remainder of 278.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 278 after subtracting 4431 from 4709.
Bring next digit (1) of the dividend behind the 278 and repeat the process: 2781 / 633

Advancing to step 6:
The number 633 fits into 2781 4 times, leaving a remainder of 249.
The next digit of our result is 4. 
Result so far: 1274.0
Subtract 2532 from 2781 to get 249.
Take the next digit (2) from the dividend and append it to 249, then repeat: 2492 / 633

Going ahead to step 7:
The number 633 fits into 2492 3 times, leaving a remainder of 593.
Record the quotient 3 as the next digit in the result. 
Result so far: 12743.0
Subtract 1899 from 2492 to get 593.
Bring next digit (9) of the dividend behind the 593 and repeat the process: 5939 / 633

Step 8:
The number 633 fits into 5939 9 times, leaving a remainder of 242.
Write down 9 as next digit of the result. 
Result so far: 127439.0
Subtract 5697 from 5939 to get 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 9:
2420 divided by 633 is 3 with a remainder of 521.
Use 3 as the next digit of our solution. 
Result so far: 127439.3
Subtracting 1899 from 2420 leaves us 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.

On to step 10:
633 goes into 5210 8 times with a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 127439.38
Subtract 5064 from 5210 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
633 goes into 1460 2 times with a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 127439.382
The remainder is 194 after subtracting 1266 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 12:
The number 633 fits into 1940 3 times, leaving a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 127439.3823
Subtract 1899 from 1940 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
410 divided by 633 is 0 with a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 127439.3823
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
633 goes into 4100 6 times with a remainder of 302.
The next digit of our result is 6. 
Result so far: 127439.382306
The remainder is 302 after subtracting 3798 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 15:
If we divide 3020 by 633, we get 4 and a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 127439.3823064
Deduct 2532 from 3020 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 16:
The number 633 fits into 4880 7 times, leaving a remainder of 449.
The number 7 becomes the next digit in our result. 
Result so far: 127439.38230647
If we take 4431 away from 4880, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

The quotient of the division is 127439.38230647, and the remainder is 4.49e-07.
