63158215 ÷ 338 
The aim is to understand the frequency of 338 in 63158215.

Moving on to step 1:
6 divided by 338 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 338

Step 2:
338 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 338

Going ahead to step 3:
The number 338 fits into 631 1 times, leaving a remainder of 293.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 338 from 631, we get 293.
Bring next digit (5) of the dividend behind the 293 and repeat the process: 2935 / 338

Let's proceed to step 4:
338 goes into 2935 8 times with a remainder of 231.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 2704 from 2935 and we're left with 231.
Take the next digit (8) from the dividend and append it to 231, then repeat: 2318 / 338

Going ahead to step 5:
338 can be fit into 2318 6 times, resulting in a remainder of 290.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we take 2028 away from 2318, we end up with 290.
Take the next digit (2) from the dividend and append it to 290, then repeat: 2902 / 338

Let's proceed to step 6:
2902 divided by 338 is 8 with a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 1868.0
Subtract 2704 from 2902 to get 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 338

Moving on to step 7:
338 goes into 1981 5 times with a remainder of 291.
Record the quotient 5 as the next digit in the result. 
Result so far: 18685.0
The remainder is 291 after subtracting 1690 from 1981.
Bring next digit (5) of the dividend behind the 291 and repeat the process: 2915 / 338

Step 8:
338 can be fit into 2915 8 times, resulting in a remainder of 211.
The number 8 becomes the next digit in our result. 
Result so far: 186858.0
Deduct 2704 from 2915 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
When dividing 2110 by 338, we get 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 186858.6
Deduct 2028 from 2110 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
820 divided by 338 is 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 186858.62
Subtracting 676 from 820 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
338 can be fit into 1440 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 186858.624
If we take 1352 away from 1440, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
The number 338 fits into 880 2 times, leaving a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 186858.6242
If we subtract 676 from 880, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
338 can be fit into 2040 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 186858.62426
If we take 2028 away from 2040, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
338 goes into 120 0 times with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 186858.62426
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
338 goes into 1200 3 times with a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 186858.6242603
Subtract 1014 from 1200 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.

Advancing to step 16:
1860 divided by 338 is 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 186858.62426035
Deduct 1690 from 1860 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 186858.62426035 with a remaining 1.7e-07.
