15162975 ÷ 209 
The aim is to understand the frequency of 209 in 15162975.

Let's proceed to step 1:
If we divide 1 by 209, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 209

Let's proceed to step 2:
209 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 209

Going ahead to step 3:
When dividing 151 by 209, we get 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Grab the next digit (6) from the dividend, add it to 151, then carry on: 1516 / 209

Moving on to step 4:
209 can be fit into 1516 7 times, resulting in a remainder of 53.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 1463 from 1516 to get 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 209

Step 5:
The number 209 fits into 532 2 times, leaving a remainder of 114.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 418 from 532 leaves us with 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 209

Advancing to step 6:
209 can be fit into 1149 5 times, resulting in a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 725.0
The remainder is 104 after subtracting 1045 from 1149.
Take the next digit (7) from the dividend and append it to 104, then repeat: 1047 / 209

Advancing to step 7:
209 can be fit into 1047 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 7255.0
The remainder is 2 after subtracting 1045 from 1047.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 209

Moving on to step 8:
The number 209 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 72550.0
If we subtract 0 from 25, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
The number 209 fits into 250 1 times, leaving a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 72550.1
If we subtract 209 from 250, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
When dividing 410 by 209, we get 1 with a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 72550.11
If we subtract 209 from 410, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The quotient of the division is 72550.11, and the remainder is 0.201.
