15216949 ÷ 322 
The aim is to understand the frequency of 322 in 15216949.

Step 1:
1 divided by 322 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 322

Advancing to step 2:
322 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 322

On to step 3:
322 can be fit into 152 0 times, resulting in a remainder of 152.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 322

Let's proceed to step 4:
If we divide 1521 by 322, we get 4 and a remainder of 233.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1288 from 1521 to get 233.
Include the next digit (6) from the dividend after 233, then repeat: 2336 / 322

Let's proceed to step 5:
322 can be fit into 2336 7 times, resulting in a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 2254 from 2336 to get 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 322

On to step 6:
322 goes into 829 2 times with a remainder of 185.
The next digit of our result is 2. 
Result so far: 472.0
If we subtract 644 from 829, we get 185.
Append the next digit (4) from the dividend to 185 and continue with: 1854 / 322

Moving on to step 7:
The number 322 fits into 1854 5 times, leaving a remainder of 244.
Record the quotient 5 as the next digit in the result. 
Result so far: 4725.0
If we take 1610 away from 1854, we end up with 244.
Append the next digit (9) from the dividend to 244 and continue with: 2449 / 322

Let's proceed to step 8:
2449 divided by 322 is 7 with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 47257.0
If we take 2254 away from 2449, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
1950 divided by 322 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 47257.6
Subtract 1932 from 1950 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
322 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 47257.6
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
322 goes into 1800 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 47257.605
The remainder is 190 after subtracting 1610 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
When dividing 1900 by 322, we get 5 with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 47257.6055
Subtracting 1610 from 1900 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Our division results in 47257.6055 with a remaining 0.0029.
