We look at the division of 12847493 by 438 
The aim is to understand the frequency of 438 in 12847493.

On to step 1:
1 divided by 438 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 438

Going ahead to step 2:
The number 438 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 438

On to step 3:
The number 438 fits into 128 0 times, leaving a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Append the next digit (4) from the dividend to 128 and continue with: 1284 / 438

Advancing to step 4:
438 goes into 1284 2 times with a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 408 after subtracting 876 from 1284.
Take the next digit (7) from the dividend and append it to 408, then repeat: 4087 / 438

Let's proceed to step 5:
4087 divided by 438 is 9 with a remainder of 145.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 3942 from 4087 to get 145.
Bring next digit (4) of the dividend behind the 145 and repeat the process: 1454 / 438

Let's proceed to step 6:
438 can be fit into 1454 3 times, resulting in a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 293.0
Subtracting 1314 from 1454 leaves us with 140.
Fetch the next digit (9) from the dividend, attach it to 140 and continue: 1409 / 438

Going ahead to step 7:
If we divide 1409 by 438, we get 3 and a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 2933.0
If we subtract 1314 from 1409, we get 95.
Take the next digit (3) from the dividend and append it to 95, then repeat: 953 / 438

Going ahead to step 8:
When dividing 953 by 438, we get 2 with a remainder of 77.
The next digit of our result is 2. 
Result so far: 29332.0
If we take 876 away from 953, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
If we divide 770 by 438, we get 1 and a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 29332.1
The remainder is 332 after subtracting 438 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
438 can be fit into 3320 7 times, resulting in a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 29332.17
Subtract 3066 from 3320 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 11:
438 can be fit into 2540 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 29332.175
Subtract 2190 from 2540 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 12:
3500 divided by 438 is 7 with a remainder of 434.
The number 7 becomes the next digit in our result. 
Result so far: 29332.1757
Subtract 3066 from 3500 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 13:
438 can be fit into 4340 9 times, resulting in a remainder of 398.
Write down 9 as next digit of the result. 
Result so far: 29332.17579
The remainder is 398 after subtracting 3942 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 14:
438 goes into 3980 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 29332.175799
If we subtract 3942 from 3980, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 29332.175799 with a balance of 3.8e-06.
