We divide 41379864 by 438
The aim is to understand the frequency of 438 in 41379864.

Step 1:
4 divided by 438 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 438

Advancing to step 2:
438 goes into 41 0 times with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 438

Moving on to step 3:
413 divided by 438 is 0 with a remainder of 413.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 413 after subtracting 0 from 413.
Include the next digit (7) from the dividend after 413, then repeat: 4137 / 438

Moving on to step 4:
The number 438 fits into 4137 9 times, leaving a remainder of 195.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 3942 from 4137 to get 195.
Bring next digit (9) of the dividend behind the 195 and repeat the process: 1959 / 438

Step 5:
The number 438 fits into 1959 4 times, leaving a remainder of 207.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtract 1752 from 1959 to get 207.
Take the next digit (8) from the dividend and append it to 207, then repeat: 2078 / 438

Let's proceed to step 6:
When dividing 2078 by 438, we get 4 with a remainder of 326.
The number 4 becomes the next digit in our result. 
Result so far: 944.0
Subtract 1752 from 2078 to get 326.
Append the next digit (6) from the dividend to 326 and continue with: 3266 / 438

Moving on to step 7:
When dividing 3266 by 438, we get 7 with a remainder of 200.
The next digit of our result is 7. 
Result so far: 9447.0
Subtract 3066 from 3266 to get 200.
Fetch the next digit (4) from the dividend, attach it to 200 and continue: 2004 / 438

Going ahead to step 8:
2004 divided by 438 is 4 with a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 94474.0
If we take 1752 away from 2004, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
If we divide 2520 by 438, we get 5 and a remainder of 330.
The next digit of our result is 5. 
Result so far: 94474.5
Subtract 2190 from 2520 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
When dividing 3300 by 438, we get 7 with a remainder of 234.
The next digit of our result is 7. 
Result so far: 94474.57
Deduct 3066 from 3300 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 11:
The number 438 fits into 2340 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 94474.575
The remainder is 150 after subtracting 2190 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
If we divide 1500 by 438, we get 3 and a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 94474.5753
Subtract 1314 from 1500 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 13:
438 can be fit into 1860 4 times, resulting in a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 94474.57534
Deduct 1752 from 1860 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 14:
The number 438 fits into 1080 2 times, leaving a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 94474.575342
The remainder is 204 after subtracting 876 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
If we divide 2040 by 438, we get 4 and a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 94474.5753424
If we take 1752 away from 2040, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 16:
438 can be fit into 2880 6 times, resulting in a remainder of 252.
Use 6 as the next digit of our solution. 
Result so far: 94474.57534246
The remainder is 252 after subtracting 2628 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The quotient of the division is 94474.57534246, and the remainder is 2.52e-07.
