We're dividing 29719419 by 412 
The aim is to understand the frequency of 412 in 29719419.

Step 1:
If we divide 2 by 412, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 412

Moving on to step 2:
29 divided by 412 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 412

Advancing to step 3:
412 can be fit into 297 0 times, resulting in a remainder of 297.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 297 to get 297.
Bring next digit (1) of the dividend behind the 297 and repeat the process: 2971 / 412

Step 4:
2971 divided by 412 is 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 2884 away from 2971, we end up with 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 412

Going ahead to step 5:
If we divide 879 by 412, we get 2 and a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 824 from 879 leaves us with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 412

Let's proceed to step 6:
If we divide 554 by 412, we get 1 and a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we subtract 412 from 554, we get 142.
Include the next digit (1) from the dividend after 142, then repeat: 1421 / 412

Let's proceed to step 7:
412 can be fit into 1421 3 times, resulting in a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 7213.0
If we take 1236 away from 1421, we end up with 185.
Include the next digit (9) from the dividend after 185, then repeat: 1859 / 412

Going ahead to step 8:
When dividing 1859 by 412, we get 4 with a remainder of 211.
Record the quotient 4 as the next digit in the result. 
Result so far: 72134.0
If we take 1648 away from 1859, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
The number 412 fits into 2110 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 72134.5
If we take 2060 away from 2110, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 412, we get 1 and a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 72134.51
If we take 412 away from 500, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
The number 412 fits into 880 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 72134.512
Subtracting 824 from 880 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
412 can be fit into 560 1 times, resulting in a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 72134.5121
Deduct 412 from 560 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
412 goes into 1480 3 times with a remainder of 244.
Put 3 as the next digit of the answer. 
Result so far: 72134.51213
The remainder is 244 after subtracting 1236 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 14:
If we divide 2440 by 412, we get 5 and a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 72134.512135
Deduct 2060 from 2440 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
If we divide 3800 by 412, we get 9 and a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 72134.5121359
If we subtract 3708 from 3800, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 16:
412 goes into 920 2 times with a remainder of 96.
The next digit of our result is 2. 
Result so far: 72134.51213592
Subtracting 824 from 920 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 72134.51213592, with a leftover of 9.6e-08.
