We look at the division of 80843193 by 634 
The aim is to understand the frequency of 634 in 80843193.

Moving on to step 1:
8 divided by 634 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 634

Moving on to step 2:
If we divide 80 by 634, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 634

Advancing to step 3:
634 can be fit into 808 1 times, resulting in a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 634 from 808 and we're left with 174.
Append the next digit (4) from the dividend to 174 and continue with: 1744 / 634

Let's proceed to step 4:
634 goes into 1744 2 times with a remainder of 476.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1268 from 1744 to get 476.
Bring next digit (3) of the dividend behind the 476 and repeat the process: 4763 / 634

Let's proceed to step 5:
634 can be fit into 4763 7 times, resulting in a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 4438 from 4763 to get 325.
Grab the next digit (1) from the dividend, add it to 325, then carry on: 3251 / 634

Moving on to step 6:
If we divide 3251 by 634, we get 5 and a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 1275.0
Subtract 3170 from 3251 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 634

Advancing to step 7:
819 divided by 634 is 1 with a remainder of 185.
Put 1 as the next digit of the answer. 
Result so far: 12751.0
If we subtract 634 from 819, we get 185.
Include the next digit (3) from the dividend after 185, then repeat: 1853 / 634

Going ahead to step 8:
When dividing 1853 by 634, we get 2 with a remainder of 585.
Write down 2 as next digit of the result. 
Result so far: 127512.0
Deduct 1268 from 1853 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 9:
634 can be fit into 5850 9 times, resulting in a remainder of 144.
Write down 9 as next digit of the result. 
Result so far: 127512.9
If we take 5706 away from 5850, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 10:
When dividing 1440 by 634, we get 2 with a remainder of 172.
The next digit of our result is 2. 
Result so far: 127512.92
Subtract 1268 from 1440 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
When dividing 1720 by 634, we get 2 with a remainder of 452.
The next digit of our result is 2. 
Result so far: 127512.922
The remainder is 452 after subtracting 1268 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 127512.922, with a leftover of 0.0452.
