We look at the division of 77700284 by 209 
The aim is to understand the frequency of 209 in 77700284.

Step 1:
When dividing 7 by 209, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 209

On to step 2:
209 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 209

Step 3:
The number 209 fits into 777 3 times, leaving a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 150 after subtracting 627 from 777.
Append the next digit (0) from the dividend to 150 and continue with: 1500 / 209

On to step 4:
209 can be fit into 1500 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 1463 from 1500 leaves us with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 209

Let's proceed to step 5:
The number 209 fits into 370 1 times, leaving a remainder of 161.
The next digit of our result is 1. 
Result so far: 371.0
Deduct 209 from 370 and we're left with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 209

Step 6:
209 can be fit into 1612 7 times, resulting in a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 3717.0
The remainder is 149 after subtracting 1463 from 1612.
Grab the next digit (8) from the dividend, add it to 149, then carry on: 1498 / 209

On to step 7:
The number 209 fits into 1498 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 37177.0
If we take 1463 away from 1498, we end up with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 209

Let's proceed to step 8:
209 can be fit into 354 1 times, resulting in a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 371771.0
The remainder is 145 after subtracting 209 from 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
The number 209 fits into 1450 6 times, leaving a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 371771.6
Deduct 1254 from 1450 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
If we divide 1960 by 209, we get 9 and a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 371771.69
If we take 1881 away from 1960, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
When dividing 790 by 209, we get 3 with a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 371771.693
Subtract 627 from 790 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 12:
The number 209 fits into 1630 7 times, leaving a remainder of 167.
The number 7 becomes the next digit in our result. 
Result so far: 371771.6937
Subtract 1463 from 1630 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 13:
If we divide 1670 by 209, we get 7 and a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 371771.69377
Deduct 1463 from 1670 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

In conclusion, the division gives 371771.69377 with a balance of 0.000207.
