We divide 309647 by 45
The aim is to understand the frequency of 45 in 309647.

Moving on to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 45

Step 2:
When dividing 30 by 45, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 45

Let's proceed to step 3:
The number 45 fits into 309 6 times, leaving a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 270 from 309 leaves us with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 45

Going ahead to step 4:
45 can be fit into 396 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtracting 360 from 396 leaves us with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 45

Going ahead to step 5:
If we divide 364 by 45, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 688.0
Deduct 360 from 364 and we're left with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 45

Moving on to step 6:
If we divide 47 by 45, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 6881.0
Deduct 45 from 47 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 45, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6881.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6881.04
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 45 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6881.044
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 6881.044 with a balance of 0.002.
