Let's divide 82195690 by 438
The aim is to understand the frequency of 438 in 82195690.

On to step 1:
438 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 438

Moving on to step 2:
438 can be fit into 82 0 times, resulting in a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 438

Advancing to step 3:
438 can be fit into 821 1 times, resulting in a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 438 from 821 leaves us with 383.
Bring next digit (9) of the dividend behind the 383 and repeat the process: 3839 / 438

Going ahead to step 4:
438 can be fit into 3839 8 times, resulting in a remainder of 335.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3504 from 3839, we get 335.
Append the next digit (5) from the dividend to 335 and continue with: 3355 / 438

Moving on to step 5:
If we divide 3355 by 438, we get 7 and a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
The remainder is 289 after subtracting 3066 from 3355.
Bring next digit (6) of the dividend behind the 289 and repeat the process: 2896 / 438

Let's proceed to step 6:
The number 438 fits into 2896 6 times, leaving a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 1876.0
If we subtract 2628 from 2896, we get 268.
Fetch the next digit (9) from the dividend, attach it to 268 and continue: 2689 / 438

Going ahead to step 7:
2689 divided by 438 is 6 with a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 18766.0
If we subtract 2628 from 2689, we get 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 438

Advancing to step 8:
610 divided by 438 is 1 with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 187661.0
The remainder is 172 after subtracting 438 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 9:
438 goes into 1720 3 times with a remainder of 406.
Write down 3 as next digit of the result. 
Result so far: 187661.3
Subtracting 1314 from 1720 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
When dividing 4060 by 438, we get 9 with a remainder of 118.
The number 9 becomes the next digit in our result. 
Result so far: 187661.39
Deduct 3942 from 4060 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 11:
If we divide 1180 by 438, we get 2 and a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 187661.392
Subtract 876 from 1180 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 12:
If we divide 3040 by 438, we get 6 and a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 187661.3926
Deduct 2628 from 3040 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 13:
When dividing 4120 by 438, we get 9 with a remainder of 178.
Use 9 as the next digit of our solution. 
Result so far: 187661.39269
Subtract 3942 from 4120 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 14:
When dividing 1780 by 438, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 187661.392694
The remainder is 28 after subtracting 1752 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 15:
438 can be fit into 280 0 times, resulting in a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 187661.392694
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 16:
2800 divided by 438 is 6 with a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 187661.39269406
If we subtract 2628 from 2800, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

In conclusion, the division gives 187661.39269406 with a balance of 1.72e-07.
