We divide 78136669 by 438
The aim is to understand the frequency of 438 in 78136669.

Step 1:
When dividing 7 by 438, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 438

Advancing to step 2:
438 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 438

Let's proceed to step 3:
438 can be fit into 781 1 times, resulting in a remainder of 343.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 438 from 781 and we're left with 343.
Append the next digit (3) from the dividend to 343 and continue with: 3433 / 438

Advancing to step 4:
438 goes into 3433 7 times with a remainder of 367.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3066 from 3433 to get 367.
Append the next digit (6) from the dividend to 367 and continue with: 3676 / 438

Moving on to step 5:
3676 divided by 438 is 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 172 after subtracting 3504 from 3676.
Include the next digit (6) from the dividend after 172, then repeat: 1726 / 438

Going ahead to step 6:
1726 divided by 438 is 3 with a remainder of 412.
The next digit of our result is 3. 
Result so far: 1783.0
Subtract 1314 from 1726 to get 412.
Append the next digit (6) from the dividend to 412 and continue with: 4126 / 438

Going ahead to step 7:
When dividing 4126 by 438, we get 9 with a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 17839.0
If we subtract 3942 from 4126, we get 184.
Take the next digit (9) from the dividend and append it to 184, then repeat: 1849 / 438

Let's proceed to step 8:
When dividing 1849 by 438, we get 4 with a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 178394.0
If we take 1752 away from 1849, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 9:
970 divided by 438 is 2 with a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 178394.2
If we take 876 away from 970, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 10:
If we divide 940 by 438, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 178394.22
If we take 876 away from 940, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 178394.22 with a balance of 0.064.
