We divide 691460 by 45
The aim is to understand the frequency of 45 in 691460.

Step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 45

On to step 2:
When dividing 69 by 45, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 69, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 45

Let's proceed to step 3:
241 divided by 45 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 16 after subtracting 225 from 241.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 45

Step 4:
45 goes into 164 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 135 from 164 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 45

Step 5:
When dividing 296 by 45, we get 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 1536.0
Deduct 270 from 296 and we're left with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 45

Let's proceed to step 6:
45 goes into 260 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15365.0
Subtracting 225 from 260 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.

Step 7:
350 divided by 45 is 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 15365.7
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.

Let's proceed to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 15365.77
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.

The final outcome is 15365.77, with a leftover of 0.035.
