We divide 778841 by 45
The aim is to understand the frequency of 45 in 778841.

Let's proceed to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 45

On to step 2:
The number 45 fits into 77 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 77 leaves us with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 45

Moving on to step 3:
328 divided by 45 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 315 away from 328, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 45

Let's proceed to step 4:
When dividing 138 by 45, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we subtract 135 from 138, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 45

Advancing to step 5:
34 divided by 45 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 1730.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 45

Going ahead to step 6:
The number 45 fits into 341 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 17307.0
If we subtract 315 from 341, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 45, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17307.5
Subtract 225 from 260 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
45 goes into 350 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 17307.57
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 17307.577
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 17307.577 with a balance of 0.0035.
