We divide 80407764 by 209
The aim is to understand the frequency of 209 in 80407764.

Going ahead to step 1:
8 divided by 209 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 209

Going ahead to step 2:
When dividing 80 by 209, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 209

Moving on to step 3:
When dividing 804 by 209, we get 3 with a remainder of 177.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 627 from 804 to get 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 209

Step 4:
209 can be fit into 1770 8 times, resulting in a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 1672 from 1770 to get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 209

Moving on to step 5:
If we divide 987 by 209, we get 4 and a remainder of 151.
Write down 4 as next digit of the result. 
Result so far: 384.0
Subtract 836 from 987 to get 151.
Take the next digit (7) from the dividend and append it to 151, then repeat: 1517 / 209

Step 6:
If we divide 1517 by 209, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 3847.0
Subtracting 1463 from 1517 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 209

On to step 7:
209 can be fit into 546 2 times, resulting in a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 38472.0
Deduct 418 from 546 and we're left with 128.
Append the next digit (4) from the dividend to 128 and continue with: 1284 / 209

Step 8:
When dividing 1284 by 209, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 384726.0
Subtracting 1254 from 1284 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 209 fits into 300 1 times, leaving a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 384726.1
The remainder is 91 after subtracting 209 from 300.
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 10:
When dividing 910 by 209, we get 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 384726.14
Subtracting 836 from 910 leaves us 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.

Let's proceed to step 11:
The number 209 fits into 740 3 times, leaving a remainder of 113.
The next digit of our result is 3. 
Result so far: 384726.143
Subtracting 627 from 740 leaves us 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 12:
If we divide 1130 by 209, we get 5 and a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 384726.1435
The remainder is 85 after subtracting 1045 from 1130.
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 13:
209 can be fit into 850 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 384726.14354
Subtract 836 from 850 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
209 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 384726.14354
Deduct 0 from 140 and we're left 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.

Advancing to step 15:
The number 209 fits into 1400 6 times, leaving a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 384726.1435406
If we subtract 1254 from 1400, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 16:
If we divide 1460 by 209, we get 6 and a remainder of 206.
Use 6 as the next digit of our solution. 
Result so far: 384726.14354066
The remainder is 206 after subtracting 1254 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

After the division, we end up with 384726.14354066 and a remainder of 2.06e-07.
