We look at the division of 90320790 by 338 
The aim is to understand the frequency of 338 in 90320790.

Step 1:
338 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 338

Advancing to step 2:
338 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 338

Step 3:
The number 338 fits into 903 2 times, leaving a remainder of 227.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 676 from 903 leaves us with 227.
Take the next digit (2) from the dividend and append it to 227, then repeat: 2272 / 338

Advancing to step 4:
If we divide 2272 by 338, we get 6 and a remainder of 244.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 244 after subtracting 2028 from 2272.
Fetch the next digit (0) from the dividend, attach it to 244 and continue: 2440 / 338

Moving on to step 5:
If we divide 2440 by 338, we get 7 and a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 267.0
Subtracting 2366 from 2440 leaves us with 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 338

Moving on to step 6:
When dividing 747 by 338, we get 2 with a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 2672.0
Deduct 676 from 747 and we're left with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 338

Let's proceed to step 7:
The number 338 fits into 719 2 times, leaving a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 26722.0
If we take 676 away from 719, we end up with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 338

On to step 8:
338 can be fit into 430 1 times, resulting in a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 267221.0
If we subtract 338 from 430, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 9:
When dividing 920 by 338, we get 2 with a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 267221.2
Subtract 676 from 920 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 10:
2440 divided by 338 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 267221.27
If we subtract 2366 from 2440, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
740 divided by 338 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 267221.272
If we subtract 676 from 740, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
338 can be fit into 640 1 times, resulting in a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 267221.2721
The remainder is 302 after subtracting 338 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 13:
338 goes into 3020 8 times with a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 267221.27218
The remainder is 316 after subtracting 2704 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 14:
When dividing 3160 by 338, we get 9 with a remainder of 118.
Write down 9 as next digit of the result. 
Result so far: 267221.272189
If we subtract 3042 from 3160, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 15:
The number 338 fits into 1180 3 times, leaving a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 267221.2721893
If we take 1014 away from 1180, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 16:
1660 divided by 338 is 4 with a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 267221.27218934
Subtracting 1352 from 1660 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final outcome is 267221.27218934, with a leftover of 3.08e-07.
