We look at the division of 48999827 by 438 
The aim is to understand the frequency of 438 in 48999827.

Going ahead to step 1:
438 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 438

Let's proceed to step 2:
The number 438 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 438

Step 3:
The number 438 fits into 489 1 times, leaving a remainder of 51.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 438 from 489 and we're left with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 438

Going ahead to step 4:
519 divided by 438 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 438 from 519, we get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 438

Step 5:
438 goes into 819 1 times with a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 111.0
The remainder is 381 after subtracting 438 from 819.
Append the next digit (8) from the dividend to 381 and continue with: 3818 / 438

Let's proceed to step 6:
3818 divided by 438 is 8 with a remainder of 314.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
Subtracting 3504 from 3818 leaves us with 314.
Include the next digit (2) from the dividend after 314, then repeat: 3142 / 438

Step 7:
When dividing 3142 by 438, we get 7 with a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 11187.0
Deduct 3066 from 3142 and we're left with 76.
Grab the next digit (7) from the dividend, add it to 76, then carry on: 767 / 438

Moving on to step 8:
767 divided by 438 is 1 with a remainder of 329.
The next digit of our result is 1. 
Result so far: 111871.0
Subtract 438 from 767 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 9:
438 goes into 3290 7 times with a remainder of 224.
The number 7 becomes the next digit in our result. 
Result so far: 111871.7
Subtract 3066 from 3290 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 10:
438 can be fit into 2240 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 111871.75
If we take 2190 away from 2240, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 438, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 111871.751
The remainder is 62 after subtracting 438 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
438 goes into 620 1 times with a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 111871.7511
Subtract 438 from 620 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Our division results in 111871.7511 with a remaining 0.00182.
