We look at the division of 2577502 by 338 
The aim is to understand the frequency of 338 in 2577502.

Going ahead to step 1:
2 divided by 338 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 338

Step 2:
25 divided by 338 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 338

Let's proceed to step 3:
338 goes into 257 0 times with a remainder of 257.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 257, we end up with 257.
Fetch the next digit (7) from the dividend, attach it to 257 and continue: 2577 / 338

Going ahead to step 4:
If we divide 2577 by 338, we get 7 and a remainder of 211.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 211 after subtracting 2366 from 2577.
Take the next digit (5) from the dividend and append it to 211, then repeat: 2115 / 338

Advancing to step 5:
If we divide 2115 by 338, we get 6 and a remainder of 87.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 2028 from 2115, we get 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 338

Advancing to step 6:
870 divided by 338 is 2 with a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 762.0
If we subtract 676 from 870, we get 194.
Include the next digit (2) from the dividend after 194, then repeat: 1942 / 338

Going ahead to step 7:
If we divide 1942 by 338, we get 5 and a remainder of 252.
Record the quotient 5 as the next digit in the result. 
Result so far: 7625.0
Deduct 1690 from 1942 and we're left 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.

Moving on to step 8:
The number 338 fits into 2520 7 times, leaving a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 7625.7
If we take 2366 away from 2520, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 9:
338 can be fit into 1540 4 times, resulting in a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 7625.74
Subtract 1352 from 1540 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
338 goes into 1880 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 7625.745
If we subtract 1690 from 1880, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
If we divide 1900 by 338, we get 5 and a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 7625.7455
Subtract 1690 from 1900 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 7625.7455 with a remaining 0.0021.
