12201216 ÷ 782 
The aim is to understand the frequency of 782 in 12201216.

Advancing to step 1:
The number 782 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 782

Advancing to step 2:
The number 782 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 782

Step 3:
The number 782 fits into 122 0 times, leaving a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Append the next digit (0) from the dividend to 122 and continue with: 1220 / 782

Advancing to step 4:
782 goes into 1220 1 times with a remainder of 438.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 782 from 1220 to get 438.
Bring next digit (1) of the dividend behind the 438 and repeat the process: 4381 / 782

Going ahead to step 5:
4381 divided by 782 is 5 with a remainder of 471.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 3910 from 4381 and we're left with 471.
Grab the next digit (2) from the dividend, add it to 471, then carry on: 4712 / 782

Let's proceed to step 6:
When dividing 4712 by 782, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 156.0
The remainder is 20 after subtracting 4692 from 4712.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 782

Advancing to step 7:
When dividing 201 by 782, we get 0 with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 1560.0
Subtract 0 from 201 to get 201.
Include the next digit (6) from the dividend after 201, then repeat: 2016 / 782

Moving on to step 8:
If we divide 2016 by 782, we get 2 and a remainder of 452.
The next digit of our result is 2. 
Result so far: 15602.0
The remainder is 452 after subtracting 1564 from 2016.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 9:
The number 782 fits into 4520 5 times, leaving a remainder of 610.
The next digit of our result is 5. 
Result so far: 15602.5
Deduct 3910 from 4520 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 10:
If we divide 6100 by 782, we get 7 and a remainder of 626.
Use 7 as the next digit of our solution. 
Result so far: 15602.57
If we subtract 5474 from 6100, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 11:
When dividing 6260 by 782, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15602.578
Subtracting 6256 from 6260 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
782 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15602.578
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
400 divided by 782 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 15602.578
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 15602.578 with a remaining 0.0004.
