The aim is to understand the frequency of 209 in 77389413.

Moving on to step 1:
The number 209 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 209

On to step 2:
209 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 209

Step 3:
209 goes into 773 3 times with a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 146 after subtracting 627 from 773.
Take the next digit (8) from the dividend and append it to 146, then repeat: 1468 / 209

Moving on to step 4:
209 can be fit into 1468 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 1463 from 1468 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 209

Going ahead to step 5:
59 divided by 209 is 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 370.0
Subtracting 0 from 59 leaves us with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 209

Going ahead to step 6:
209 goes into 594 2 times with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 3702.0
Deduct 418 from 594 and we're left with 176.
Fetch the next digit (1) from the dividend, attach it to 176 and continue: 1761 / 209

Moving on to step 7:
When dividing 1761 by 209, we get 8 with a remainder of 89.
The number 8 becomes the next digit in our result. 
Result so far: 37028.0
Subtracting 1672 from 1761 leaves us with 89.
Grab the next digit (3) from the dividend, add it to 89, then carry on: 893 / 209

On to step 8:
The number 209 fits into 893 4 times, leaving a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 370284.0
Subtracting 836 from 893 leaves us with 57.

The number 209 fits into 570 2 times, leaving a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 370284.2
If we take 418 away from 570, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
The number 209 fits into 1520 7 times, leaving a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 370284.27
Deduct 1463 from 1520 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
209 can be fit into 570 2 times, resulting in a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 370284.272
Subtract 418 from 570 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
The number 209 fits into 1520 7 times, leaving a remainder of 57.
The next digit of our result is 7. 
Result so far: 370284.2727
If we take 1463 away from 1520, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 13:
209 can be fit into 570 2 times, resulting in a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 370284.27272
Deduct 418 from 570 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
1520 divided by 209 is 7 with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 370284.272727
If we take 1463 away from 1520, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.
