16594649 ÷ 344 
The aim is to understand the frequency of 344 in 16594649.

On to step 1:
If we divide 1 by 344, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 344

Advancing to step 2:
If we divide 16 by 344, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 344

Let's proceed to step 3:
344 goes into 165 0 times with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 165 after subtracting 0 from 165.
Fetch the next digit (9) from the dividend, attach it to 165 and continue: 1659 / 344

Let's proceed to step 4:
1659 divided by 344 is 4 with a remainder of 283.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1376 from 1659 and we're left with 283.
Take the next digit (4) from the dividend and append it to 283, then repeat: 2834 / 344

Let's proceed to step 5:
When dividing 2834 by 344, we get 8 with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 2752 from 2834 and we're left with 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 344

On to step 6:
826 divided by 344 is 2 with a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 482.0
The remainder is 138 after subtracting 688 from 826.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 344

Step 7:
If we divide 1384 by 344, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4824.0
If we subtract 1376 from 1384, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 344

On to step 8:
344 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 48240.0
Deduct 0 from 89 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
If we divide 890 by 344, we get 2 and a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 48240.2
If we subtract 688 from 890, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
The number 344 fits into 2020 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 48240.25
Deduct 1720 from 2020 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
344 goes into 3000 8 times with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 48240.258
If we take 2752 away from 3000, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
The number 344 fits into 2480 7 times, leaving a remainder of 72.
The next digit of our result is 7. 
Result so far: 48240.2587
If we take 2408 away from 2480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
344 can be fit into 720 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 48240.25872
The remainder is 32 after subtracting 688 from 720.
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 14:
The number 344 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 48240.25872
Deduct 0 from 320 and we're left 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.

On to step 15:
When dividing 3200 by 344, we get 9 with a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 48240.2587209
Deduct 3096 from 3200 and we're left 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.

Moving on to step 16:
If we divide 1040 by 344, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 48240.25872093
Deduct 1032 from 1040 and we're left 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.

The quotient of the division is 48240.25872093, and the remainder is 8e-09.
