Let's divide 29116734 by 645
The aim is to understand the frequency of 645 in 29116734.

Let's proceed to step 1:
If we divide 2 by 645, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 645

Step 2:
29 divided by 645 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 645

Let's proceed to step 3:
645 can be fit into 291 0 times, resulting in a remainder of 291.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 291 to get 291.
Append the next digit (1) from the dividend to 291 and continue with: 2911 / 645

Step 4:
2911 divided by 645 is 4 with a remainder of 331.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2580 away from 2911, we end up with 331.
Take the next digit (6) from the dividend and append it to 331, then repeat: 3316 / 645

Let's proceed to step 5:
645 can be fit into 3316 5 times, resulting in a remainder of 91.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 3225 from 3316 to get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 645

Going ahead to step 6:
917 divided by 645 is 1 with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 451.0
If we subtract 645 from 917, we get 272.
Append the next digit (3) from the dividend to 272 and continue with: 2723 / 645

Step 7:
If we divide 2723 by 645, we get 4 and a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 4514.0
Subtracting 2580 from 2723 leaves us with 143.
Include the next digit (4) from the dividend after 143, then repeat: 1434 / 645

Going ahead to step 8:
1434 divided by 645 is 2 with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 45142.0
Subtracting 1290 from 1434 leaves us 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.

Let's proceed to step 9:
The number 645 fits into 1440 2 times, leaving a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 45142.2
Deduct 1290 from 1440 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
645 goes into 1500 2 times with a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 45142.22
If we subtract 1290 from 1500, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 45142.22 with a balance of 0.21.
