4280937 ÷ 209 
The aim is to understand the frequency of 209 in 4280937.

Going ahead to step 1:
209 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 209

Step 2:
209 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 209

On to step 3:
209 goes into 428 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 418 away from 428, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 209

Step 4:
100 divided by 209 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 100 and we're left with 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 209

Advancing to step 5:
209 goes into 1009 4 times with a remainder of 173.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
The remainder is 173 after subtracting 836 from 1009.
Bring next digit (3) of the dividend behind the 173 and repeat the process: 1733 / 209

Moving on to step 6:
If we divide 1733 by 209, we get 8 and a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 2048.0
Subtract 1672 from 1733 to get 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 209

Step 7:
The number 209 fits into 617 2 times, leaving a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 20482.0
If we take 418 away from 617, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 8:
If we divide 1990 by 209, we get 9 and a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 20482.9
Subtracting 1881 from 1990 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 9:
When dividing 1090 by 209, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 20482.95
Subtract 1045 from 1090 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 209 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 20482.952
If we take 418 away from 450, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 209 fits into 320 1 times, leaving a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 20482.9521
The remainder is 111 after subtracting 209 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 12:
209 goes into 1110 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 20482.95215
Subtract 1045 from 1110 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 13:
The number 209 fits into 650 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 20482.952153
If we subtract 627 from 650, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
209 can be fit into 230 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 20482.9521531
If we take 209 away from 230, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 15:
The number 209 fits into 210 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 20482.95215311
If we subtract 209 from 210, 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.

In conclusion, the division gives 20482.95215311 with a balance of 1e-09.
