Let's divide 76274852 by 209
The aim is to understand the frequency of 209 in 76274852.

Advancing to step 1:
If we divide 7 by 209, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 209

Going ahead to step 2:
The number 209 fits into 76 0 times, leaving a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 209

Going ahead to step 3:
When dividing 762 by 209, we get 3 with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 627 from 762, we get 135.
Take the next digit (7) from the dividend and append it to 135, then repeat: 1357 / 209

Going ahead to step 4:
When dividing 1357 by 209, we get 6 with a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 1254 from 1357 to get 103.
Take the next digit (4) from the dividend and append it to 103, then repeat: 1034 / 209

Step 5:
209 can be fit into 1034 4 times, resulting in a remainder of 198.
The next digit of our result is 4. 
Result so far: 364.0
Subtracting 836 from 1034 leaves us with 198.
Take the next digit (8) from the dividend and append it to 198, then repeat: 1988 / 209

Step 6:
209 goes into 1988 9 times with a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 3649.0
Subtracting 1881 from 1988 leaves us with 107.
Append the next digit (5) from the dividend to 107 and continue with: 1075 / 209

On to step 7:
209 goes into 1075 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 36495.0
Subtracting 1045 from 1075 leaves us with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 209

On to step 8:
When dividing 302 by 209, we get 1 with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 364951.0
Deduct 209 from 302 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
209 goes into 930 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 364951.4
Deduct 836 from 930 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 10:
209 goes into 940 4 times with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 364951.44
The remainder is 104 after subtracting 836 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 364951.44 with a remainder of 0.104.
