We look at the division of 40333964 by 209 
The aim is to understand the frequency of 209 in 40333964.

Step 1:
209 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 209

Going ahead to step 2:
40 divided by 209 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 209

Advancing to step 3:
The number 209 fits into 403 1 times, leaving a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 194 after subtracting 209 from 403.
Bring next digit (3) of the dividend behind the 194 and repeat the process: 1943 / 209

Going ahead to step 4:
The number 209 fits into 1943 9 times, leaving a remainder of 62.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 1881 from 1943 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 209

Going ahead to step 5:
If we divide 623 by 209, we get 2 and a remainder of 205.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
Subtract 418 from 623 to get 205.
Grab the next digit (9) from the dividend, add it to 205, then carry on: 2059 / 209

Advancing to step 6:
209 goes into 2059 9 times with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 1929.0
If we subtract 1881 from 2059, we get 178.
Bring next digit (6) of the dividend behind the 178 and repeat the process: 1786 / 209

Step 7:
1786 divided by 209 is 8 with a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 19298.0
The remainder is 114 after subtracting 1672 from 1786.
Append the next digit (4) from the dividend to 114 and continue with: 1144 / 209

Moving on to step 8:
209 can be fit into 1144 5 times, resulting in a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 192985.0
Subtracting 1045 from 1144 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
The number 209 fits into 990 4 times, leaving a remainder of 154.
Record the quotient 4 as the next digit in the result. 
Result so far: 192985.4
If we take 836 away from 990, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
When dividing 1540 by 209, we get 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 192985.47
Deduct 1463 from 1540 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 11:
If we divide 770 by 209, we get 3 and a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 192985.473
Subtract 627 from 770 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 12:
1430 divided by 209 is 6 with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 192985.4736
Subtracting 1254 from 1430 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
When dividing 1760 by 209, we get 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 192985.47368
Deduct 1672 from 1760 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
880 divided by 209 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 192985.473684
Subtracting 836 from 880 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 15:
209 goes into 440 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 192985.4736842
If we subtract 418 from 440, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
209 can be fit into 220 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 192985.47368421
If we subtract 209 from 220, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 192985.47368421, and the remainder is 1.1e-08.
