We look at the division of 56540415 by 412 
The aim is to understand the frequency of 412 in 56540415.

Advancing to step 1:
If we divide 5 by 412, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 412

Moving on to step 2:
56 divided by 412 is 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 412

Moving on to step 3:
The number 412 fits into 565 1 times, leaving a remainder of 153.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 412 away from 565, we end up with 153.
Include the next digit (4) from the dividend after 153, then repeat: 1534 / 412

Step 4:
If we divide 1534 by 412, we get 3 and a remainder of 298.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1236 from 1534 to get 298.
Fetch the next digit (0) from the dividend, attach it to 298 and continue: 2980 / 412

Moving on to step 5:
If we divide 2980 by 412, we get 7 and a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we subtract 2884 from 2980, we get 96.
Fetch the next digit (4) from the dividend, attach it to 96 and continue: 964 / 412

Step 6:
412 goes into 964 2 times with a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 1372.0
Subtract 824 from 964 to get 140.
Append the next digit (1) from the dividend to 140 and continue with: 1401 / 412

Let's proceed to step 7:
1401 divided by 412 is 3 with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 13723.0
Deduct 1236 from 1401 and we're left with 165.
Include the next digit (5) from the dividend after 165, then repeat: 1655 / 412

Going ahead to step 8:
If we divide 1655 by 412, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 137234.0
The remainder is 7 after subtracting 1648 from 1655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 412 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 137234.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 412 fits into 700 1 times, leaving a remainder of 288.
Write down 1 as next digit of the result. 
Result so far: 137234.01
If we subtract 412 from 700, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 11:
412 goes into 2880 6 times with a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 137234.016
The remainder is 408 after subtracting 2472 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 12:
When dividing 4080 by 412, we get 9 with a remainder of 372.
Put 9 as the next digit of the answer. 
Result so far: 137234.0169
Deduct 3708 from 4080 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 13:
The number 412 fits into 3720 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 137234.01699
If we subtract 3708 from 3720, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 137234.01699, and the remainder is 1.2e-05.
