We look at the division of 63343372 by 344 
The aim is to understand the frequency of 344 in 63343372.

Moving on to step 1:
If we divide 6 by 344, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 344

Going ahead to step 2:
If we divide 63 by 344, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 344

Going ahead to step 3:
If we divide 633 by 344, we get 1 and a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 344 from 633 and we're left with 289.
Take the next digit (4) from the dividend and append it to 289, then repeat: 2894 / 344

Step 4:
344 goes into 2894 8 times with a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 2752 from 2894 to get 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 344

Going ahead to step 5:
344 can be fit into 1423 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 184.0
If we subtract 1376 from 1423, we get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 344

Let's proceed to step 6:
473 divided by 344 is 1 with a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 1841.0
If we subtract 344 from 473, we get 129.
Bring next digit (7) of the dividend behind the 129 and repeat the process: 1297 / 344

Advancing to step 7:
344 goes into 1297 3 times with a remainder of 265.
The next digit of our result is 3. 
Result so far: 18413.0
The remainder is 265 after subtracting 1032 from 1297.
Bring next digit (2) of the dividend behind the 265 and repeat the process: 2652 / 344

Advancing to step 8:
344 can be fit into 2652 7 times, resulting in a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 184137.0
Subtracting 2408 from 2652 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 9:
344 can be fit into 2440 7 times, resulting in a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 184137.7
Subtract 2408 from 2440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
320 divided by 344 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 184137.7
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
When dividing 3200 by 344, we get 9 with a remainder of 104.
Put 9 as the next digit of the answer. 
Result so far: 184137.709
If we take 3096 away from 3200, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
The number 344 fits into 1040 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 184137.7093
If we take 1032 away from 1040, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
344 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 184137.7093
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
When dividing 800 by 344, we get 2 with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 184137.709302
If we subtract 688 from 800, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
The number 344 fits into 1120 3 times, leaving a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 184137.7093023
If we subtract 1032 from 1120, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 16:
The number 344 fits into 880 2 times, leaving a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 184137.70930232
Subtract 688 from 880 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 184137.70930232, with a leftover of 1.92e-07.
