Let's divide 11897 by 45
The aim is to understand the frequency of 45 in 11897.

On to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 45

Moving on to step 2:
When dividing 11 by 45, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 45

Moving on to step 3:
45 goes into 118 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 90 away from 118, we end up with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 45

Advancing to step 4:
When dividing 289 by 45, we get 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 270 away from 289, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 45

Advancing to step 5:
When dividing 197 by 45, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
Subtract 180 from 197 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 6:
If we divide 170 by 45, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 264.3
If we subtract 135 from 170, we 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.

Let's proceed to step 7:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 264.37
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.

On to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 264.377
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.

Our division results in 264.377 with a remaining 0.0035.
