Let's divide 40438580 by 838
The aim is to understand the frequency of 838 in 40438580.

Moving on to step 1:
When dividing 4 by 838, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 838

Going ahead to step 2:
838 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 838

Moving on to step 3:
838 goes into 404 0 times with a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 404, we end up with 404.
Fetch the next digit (3) from the dividend, attach it to 404 and continue: 4043 / 838

Let's proceed to step 4:
4043 divided by 838 is 4 with a remainder of 691.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3352 from 4043 and we're left with 691.
Append the next digit (8) from the dividend to 691 and continue with: 6918 / 838

Let's proceed to step 5:
838 can be fit into 6918 8 times, resulting in a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 214 after subtracting 6704 from 6918.
Append the next digit (5) from the dividend to 214 and continue with: 2145 / 838

Going ahead to step 6:
838 can be fit into 2145 2 times, resulting in a remainder of 469.
Use 2 as the next digit of our solution. 
Result so far: 482.0
Deduct 1676 from 2145 and we're left with 469.
Grab the next digit (8) from the dividend, add it to 469, then carry on: 4698 / 838

Moving on to step 7:
838 goes into 4698 5 times with a remainder of 508.
Use 5 as the next digit of our solution. 
Result so far: 4825.0
The remainder is 508 after subtracting 4190 from 4698.
Fetch the next digit (0) from the dividend, attach it to 508 and continue: 5080 / 838

Going ahead to step 8:
The number 838 fits into 5080 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 48256.0
The remainder is 52 after subtracting 5028 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
The number 838 fits into 520 0 times, leaving a remainder of 520.
The next digit of our result is 0. 
Result so far: 48256.0
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
If we divide 5200 by 838, we get 6 and a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 48256.06
Deduct 5028 from 5200 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
1720 divided by 838 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 48256.062
If we take 1676 away from 1720, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
If we divide 440 by 838, we get 0 and a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 48256.062
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 13:
If we divide 4400 by 838, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 48256.06205
If we take 4190 away from 4400, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 14:
838 goes into 2100 2 times with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 48256.062052
If we take 1676 away from 2100, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 15:
When dividing 4240 by 838, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 48256.0620525
If we subtract 4190 from 4240, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
838 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 48256.0620525
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 48256.0620525 with a balance of 5e-07.
