We look at the division of 7007777 by 326 
The aim is to understand the frequency of 326 in 7007777.

Moving on to step 1:
326 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 326

Moving on to step 2:
If we divide 70 by 326, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 326

Let's proceed to step 3:
326 goes into 700 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2.0
If we take 652 away from 700, we end up with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 326

Step 4:
326 goes into 487 1 times with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 326 from 487 and we're left with 161.
Fetch the next digit (7) from the dividend, attach it to 161 and continue: 1617 / 326

Advancing to step 5:
The number 326 fits into 1617 4 times, leaving a remainder of 313.
Write down 4 as next digit of the result. 
Result so far: 214.0
The remainder is 313 after subtracting 1304 from 1617.
Append the next digit (7) from the dividend to 313 and continue with: 3137 / 326

On to step 6:
3137 divided by 326 is 9 with a remainder of 203.
The next digit of our result is 9. 
Result so far: 2149.0
If we take 2934 away from 3137, we end up with 203.
Grab the next digit (7) from the dividend, add it to 203, then carry on: 2037 / 326

Step 7:
The number 326 fits into 2037 6 times, leaving a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 21496.0
Subtracting 1956 from 2037 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
The number 326 fits into 810 2 times, leaving a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 21496.2
If we take 652 away from 810, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
The number 326 fits into 1580 4 times, leaving a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 21496.24
If we subtract 1304 from 1580, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
The number 326 fits into 2760 8 times, leaving a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 21496.248
Deduct 2608 from 2760 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.

Step 11:
326 can be fit into 1520 4 times, resulting in a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 21496.2484
Subtract 1304 from 1520 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
326 can be fit into 2160 6 times, resulting in a remainder of 204.
The next digit of our result is 6. 
Result so far: 21496.24846
Deduct 1956 from 2160 and we're left 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.

Moving on to step 13:
The number 326 fits into 2040 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 21496.248466
The remainder is 84 after subtracting 1956 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 21496.248466 with a balance of 8.4e-06.
