Let's divide 766261 by 45
The aim is to understand the frequency of 45 in 766261.

Advancing to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 45

Advancing to step 2:
When dividing 76 by 45, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 76 leaves us with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 45

Step 3:
316 divided by 45 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 1 after subtracting 315 from 316.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 45

Let's proceed to step 4:
If we divide 12 by 45, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 45

Going ahead to step 5:
45 goes into 126 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1702.0
The remainder is 36 after subtracting 90 from 126.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 45

Going ahead to step 6:
45 goes into 361 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 17028.0
If we subtract 360 from 361, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 45 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 17028.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 17028.02
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 17028.022
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 17028.022 with a remainder of 0.001.
