We're dividing 43551347 by 338 
The aim is to understand the frequency of 338 in 43551347.

Step 1:
When dividing 4 by 338, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 338

On to step 2:
If we divide 43 by 338, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 338

On to step 3:
If we divide 435 by 338, we get 1 and a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 338 from 435, we get 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 338

Going ahead to step 4:
338 goes into 975 2 times with a remainder of 299.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 676 from 975 and we're left with 299.
Bring next digit (1) of the dividend behind the 299 and repeat the process: 2991 / 338

Going ahead to step 5:
If we divide 2991 by 338, we get 8 and a remainder of 287.
Use 8 as the next digit of our solution. 
Result so far: 128.0
If we subtract 2704 from 2991, we get 287.
Append the next digit (3) from the dividend to 287 and continue with: 2873 / 338

Advancing to step 6:
338 goes into 2873 8 times with a remainder of 169.
Write down 8 as next digit of the result. 
Result so far: 1288.0
Subtracting 2704 from 2873 leaves us with 169.
Grab the next digit (4) from the dividend, add it to 169, then carry on: 1694 / 338

Moving on to step 7:
338 can be fit into 1694 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 12885.0
If we subtract 1690 from 1694, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 338

Advancing to step 8:
When dividing 47 by 338, we get 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 128850.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
The number 338 fits into 470 1 times, leaving a remainder of 132.
The next digit of our result is 1. 
Result so far: 128850.1
The remainder is 132 after subtracting 338 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
The number 338 fits into 1320 3 times, leaving a remainder of 306.
The number 3 becomes the next digit in our result. 
Result so far: 128850.13
Subtract 1014 from 1320 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 11:
If we divide 3060 by 338, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 128850.139
Deduct 3042 from 3060 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 338, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 128850.139
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
If we divide 1800 by 338, we get 5 and a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 128850.13905
If we subtract 1690 from 1800, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 14:
1100 divided by 338 is 3 with a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 128850.139053
Subtract 1014 from 1100 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 15:
338 can be fit into 860 2 times, resulting in a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 128850.1390532
Deduct 676 from 860 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
338 goes into 1840 5 times with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 128850.13905325
If we subtract 1690 from 1840, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 128850.13905325, with a leftover of 1.5e-07.
