We look at the division of 23972715 by 209 
The aim is to understand the frequency of 209 in 23972715.

Moving on to step 1:
2 divided by 209 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 209

Step 2:
23 divided by 209 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 209

Step 3:
When dividing 239 by 209, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we take 209 away from 239, we end up with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 209

On to step 4:
The number 209 fits into 307 1 times, leaving a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 209 from 307 leaves us with 98.
Take the next digit (2) from the dividend and append it to 98, then repeat: 982 / 209

Moving on to step 5:
If we divide 982 by 209, we get 4 and a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 146 after subtracting 836 from 982.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 209

Moving on to step 6:
209 goes into 1467 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1147.0
Deduct 1463 from 1467 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 209

Step 7:
If we divide 41 by 209, we get 0 and a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 11470.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 209

Let's proceed to step 8:
209 goes into 415 1 times with a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 114701.0
If we subtract 209 from 415, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
2060 divided by 209 is 9 with a remainder of 179.
Record the quotient 9 as the next digit in the result. 
Result so far: 114701.9
If we subtract 1881 from 2060, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 10:
209 can be fit into 1790 8 times, resulting in a remainder of 118.
Use 8 as the next digit of our solution. 
Result so far: 114701.98
Subtract 1672 from 1790 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
If we divide 1180 by 209, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 114701.985
Subtract 1045 from 1180 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 12:
209 goes into 1350 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 114701.9856
Subtract 1254 from 1350 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
If we divide 960 by 209, we get 4 and a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 114701.98564
Subtract 836 from 960 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 14:
1240 divided by 209 is 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 114701.985645
Subtract 1045 from 1240 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 15:
The number 209 fits into 1950 9 times, leaving a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 114701.9856459
If we take 1881 away from 1950, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 16:
690 divided by 209 is 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 114701.98564593
Deduct 627 from 690 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 114701.98564593, and the remainder is 6.3e-08.
