Let's divide 91184255 by 209
The aim is to understand the frequency of 209 in 91184255.

Advancing to step 1:
209 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 209

Step 2:
209 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 209

Going ahead to step 3:
The number 209 fits into 911 4 times, leaving a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 836 from 911 to get 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 209

Let's proceed to step 4:
The number 209 fits into 758 3 times, leaving a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 627 from 758, we get 131.
Fetch the next digit (4) from the dividend, attach it to 131 and continue: 1314 / 209

Advancing to step 5:
When dividing 1314 by 209, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 436.0
If we subtract 1254 from 1314, we get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 209

Advancing to step 6:
The number 209 fits into 602 2 times, leaving a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 4362.0
Deduct 418 from 602 and we're left with 184.
Fetch the next digit (5) from the dividend, attach it to 184 and continue: 1845 / 209

Let's proceed to step 7:
209 can be fit into 1845 8 times, resulting in a remainder of 173.
Put 8 as the next digit of the answer. 
Result so far: 43628.0
Subtracting 1672 from 1845 leaves us with 173.
Fetch the next digit (5) from the dividend, attach it to 173 and continue: 1735 / 209

Advancing to step 8:
When dividing 1735 by 209, we get 8 with a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 436288.0
Subtracting 1672 from 1735 leaves us 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.

On to step 9:
When dividing 630 by 209, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 436288.3
Subtract 627 from 630 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 209 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 436288.3
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
209 goes into 300 1 times with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 436288.301
If we subtract 209 from 300, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 12:
209 goes into 910 4 times with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 436288.3014
Deduct 836 from 910 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
When dividing 740 by 209, we get 3 with a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 436288.30143
Deduct 627 from 740 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 14:
If we divide 1130 by 209, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 436288.301435
Subtracting 1045 from 1130 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
850 divided by 209 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 436288.3014354
Deduct 836 from 850 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 16:
140 divided by 209 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 436288.3014354
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 436288.3014354 and a remainder of 1.4e-07.
