We look at the division of 39005394 by 213 
The aim is to understand the frequency of 213 in 39005394.

On to step 1:
When dividing 3 by 213, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 213

On to step 2:
When dividing 39 by 213, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 213

Moving on to step 3:
When dividing 390 by 213, we get 1 with a remainder of 177.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 213 from 390 and we're left with 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 213

On to step 4:
When dividing 1770 by 213, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 1704 from 1770 and we're left with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 213

On to step 5:
The number 213 fits into 665 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 183.0
The remainder is 26 after subtracting 639 from 665.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 213

Going ahead to step 6:
When dividing 263 by 213, we get 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1831.0
If we subtract 213 from 263, we get 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 213

Going ahead to step 7:
The number 213 fits into 509 2 times, leaving a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 18312.0
Deduct 426 from 509 and we're left with 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 213

Let's proceed to step 8:
The number 213 fits into 834 3 times, leaving a remainder of 195.
The next digit of our result is 3. 
Result so far: 183123.0
Subtract 639 from 834 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 9:
If we divide 1950 by 213, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 183123.9
The remainder is 33 after subtracting 1917 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
The number 213 fits into 330 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 183123.91
The remainder is 117 after subtracting 213 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 11:
1170 divided by 213 is 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 183123.915
The remainder is 105 after subtracting 1065 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
213 goes into 1050 4 times with a remainder of 198.
Record the quotient 4 as the next digit in the result. 
Result so far: 183123.9154
Deduct 852 from 1050 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 13:
213 goes into 1980 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 183123.91549
Subtracting 1917 from 1980 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.

Step 14:
When dividing 630 by 213, we get 2 with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 183123.915492
If we take 426 away from 630, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 15:
213 can be fit into 2040 9 times, resulting in a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 183123.9154929
Subtracting 1917 from 2040 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 16:
The number 213 fits into 1230 5 times, leaving a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 183123.91549295
Subtract 1065 from 1230 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

In conclusion, the division gives 183123.91549295 with a balance of 1.65e-07.
