We look at the division of 30562524 by 391 
The aim is to understand the frequency of 391 in 30562524.

Let's proceed to step 1:
When dividing 3 by 391, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 391

Advancing to step 2:
The number 391 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 391

Let's proceed to step 3:
391 can be fit into 305 0 times, resulting in a remainder of 305.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 305 and we're left with 305.
Append the next digit (6) from the dividend to 305 and continue with: 3056 / 391

Let's proceed to step 4:
3056 divided by 391 is 7 with a remainder of 319.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2737 from 3056 and we're left with 319.
Include the next digit (2) from the dividend after 319, then repeat: 3192 / 391

Advancing to step 5:
When dividing 3192 by 391, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 64 after subtracting 3128 from 3192.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 391

Moving on to step 6:
391 goes into 645 1 times with a remainder of 254.
Put 1 as the next digit of the answer. 
Result so far: 781.0
If we subtract 391 from 645, we get 254.
Grab the next digit (2) from the dividend, add it to 254, then carry on: 2542 / 391

Advancing to step 7:
If we divide 2542 by 391, we get 6 and a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 7816.0
If we take 2346 away from 2542, we end up with 196.
Take the next digit (4) from the dividend and append it to 196, then repeat: 1964 / 391

Let's proceed to step 8:
When dividing 1964 by 391, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 78165.0
The remainder is 9 after subtracting 1955 from 1964.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
If we divide 90 by 391, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 78165.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
900 divided by 391 is 2 with a remainder of 118.
The next digit of our result is 2. 
Result so far: 78165.02
Subtract 782 from 900 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 11:
391 can be fit into 1180 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 78165.023
The remainder is 7 after subtracting 1173 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
70 divided by 391 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 78165.023
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
If we divide 700 by 391, we get 1 and a remainder of 309.
Write down 1 as next digit of the result. 
Result so far: 78165.02301
If we subtract 391 from 700, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 14:
391 goes into 3090 7 times with a remainder of 353.
Put 7 as the next digit of the answer. 
Result so far: 78165.023017
If we take 2737 away from 3090, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 15:
391 can be fit into 3530 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 78165.0230179
Subtracting 3519 from 3530 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 16:
391 goes into 110 0 times with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 78165.0230179
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 78165.0230179 with a balance of 1.1e-07.
