We look at the division of 15114311 by 344 
The aim is to understand the frequency of 344 in 15114311.

Advancing to step 1:
The number 344 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 344

Advancing to step 2:
344 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 344

Advancing to step 3:
When dividing 151 by 344, we get 0 with a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 344

Going ahead to step 4:
1511 divided by 344 is 4 with a remainder of 135.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1376 away from 1511, we end up with 135.
Grab the next digit (4) from the dividend, add it to 135, then carry on: 1354 / 344

Advancing to step 5:
If we divide 1354 by 344, we get 3 and a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 1032 away from 1354, we end up with 322.
Bring next digit (3) of the dividend behind the 322 and repeat the process: 3223 / 344

Advancing to step 6:
When dividing 3223 by 344, we get 9 with a remainder of 127.
Use 9 as the next digit of our solution. 
Result so far: 439.0
If we take 3096 away from 3223, we end up with 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 344

Let's proceed to step 7:
344 can be fit into 1271 3 times, resulting in a remainder of 239.
The next digit of our result is 3. 
Result so far: 4393.0
The remainder is 239 after subtracting 1032 from 1271.
Grab the next digit (1) from the dividend, add it to 239, then carry on: 2391 / 344

Moving on to step 8:
If we divide 2391 by 344, we get 6 and a remainder of 327.
Write down 6 as next digit of the result. 
Result so far: 43936.0
The remainder is 327 after subtracting 2064 from 2391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 9:
If we divide 3270 by 344, we get 9 and a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 43936.9
Deduct 3096 from 3270 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
The number 344 fits into 1740 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 43936.95
The remainder is 20 after subtracting 1720 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 344, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 43936.95
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
344 can be fit into 2000 5 times, resulting in a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 43936.9505
The remainder is 280 after subtracting 1720 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
2800 divided by 344 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 43936.95058
Subtracting 2752 from 2800 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
344 can be fit into 480 1 times, resulting in a remainder of 136.
The next digit of our result is 1. 
Result so far: 43936.950581
If we subtract 344 from 480, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
344 can be fit into 1360 3 times, resulting in a remainder of 328.
The next digit of our result is 3. 
Result so far: 43936.9505813
The remainder is 328 after subtracting 1032 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 16:
344 goes into 3280 9 times with a remainder of 184.
Write down 9 as next digit of the result. 
Result so far: 43936.95058139
The remainder is 184 after subtracting 3096 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 43936.95058139, with a leftover of 1.84e-07.
