We look at the division of 8007601 by 344 
The aim is to understand the frequency of 344 in 8007601.

Step 1:
The number 344 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 344

On to step 2:
If we divide 80 by 344, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 344

Going ahead to step 3:
344 can be fit into 800 2 times, resulting in a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 688 from 800 to get 112.
Append the next digit (7) from the dividend to 112 and continue with: 1127 / 344

Moving on to step 4:
344 goes into 1127 3 times with a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 95 after subtracting 1032 from 1127.
Grab the next digit (6) from the dividend, add it to 95, then carry on: 956 / 344

Moving on to step 5:
The number 344 fits into 956 2 times, leaving a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 232.0
If we take 688 away from 956, we end up with 268.
Include the next digit (0) from the dividend after 268, then repeat: 2680 / 344

Step 6:
If we divide 2680 by 344, we get 7 and a remainder of 272.
The next digit of our result is 7. 
Result so far: 2327.0
Subtracting 2408 from 2680 leaves us with 272.
Take the next digit (1) from the dividend and append it to 272, then repeat: 2721 / 344

Going ahead to step 7:
344 goes into 2721 7 times with a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 23277.0
Subtracting 2408 from 2721 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 8:
The number 344 fits into 3130 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 23277.9
Subtract 3096 from 3130 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 344 fits into 340 0 times, leaving a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 23277.9
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
The number 344 fits into 3400 9 times, leaving a remainder of 304.
The next digit of our result is 9. 
Result so far: 23277.909
If we take 3096 away from 3400, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
3040 divided by 344 is 8 with a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 23277.9098
If we subtract 2752 from 3040, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
344 can be fit into 2880 8 times, resulting in a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 23277.90988
The remainder is 128 after subtracting 2752 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 23277.90988 and a remainder of 0.000128.
