We look at the division of 80398170 by 341 
The aim is to understand the frequency of 341 in 80398170.

On to step 1:
8 divided by 341 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 341

Going ahead to step 2:
When dividing 80 by 341, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 341

Step 3:
803 divided by 341 is 2 with a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 121 after subtracting 682 from 803.
Grab the next digit (9) from the dividend, add it to 121, then carry on: 1219 / 341

Advancing to step 4:
341 can be fit into 1219 3 times, resulting in a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 1023 from 1219 leaves us with 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 341

Advancing to step 5:
If we divide 1968 by 341, we get 5 and a remainder of 263.
The next digit of our result is 5. 
Result so far: 235.0
If we subtract 1705 from 1968, we get 263.
Fetch the next digit (1) from the dividend, attach it to 263 and continue: 2631 / 341

Going ahead to step 6:
If we divide 2631 by 341, we get 7 and a remainder of 244.
The next digit of our result is 7. 
Result so far: 2357.0
The remainder is 244 after subtracting 2387 from 2631.
Grab the next digit (7) from the dividend, add it to 244, then carry on: 2447 / 341

Moving on to step 7:
341 can be fit into 2447 7 times, resulting in a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 23577.0
Subtract 2387 from 2447 to get 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 341

On to step 8:
If we divide 600 by 341, we get 1 and a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 235771.0
The remainder is 259 after subtracting 341 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 9:
341 goes into 2590 7 times with a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 235771.7
Subtracting 2387 from 2590 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 10:
341 goes into 2030 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 235771.75
Deduct 1705 from 2030 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 11:
3250 divided by 341 is 9 with a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 235771.759
Subtracting 3069 from 3250 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 12:
341 goes into 1810 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 235771.7595
If we take 1705 away from 1810, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
The number 341 fits into 1050 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 235771.75953
The remainder is 27 after subtracting 1023 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
341 can be fit into 270 0 times, resulting in a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 235771.75953
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 15:
341 goes into 2700 7 times with a remainder of 313.
Write down 7 as next digit of the result. 
Result so far: 235771.7595307
If we take 2387 away from 2700, we end up 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.

Step 16:
When dividing 3130 by 341, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 235771.75953079
Subtracting 3069 from 3130 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

In conclusion, the division gives 235771.75953079 with a balance of 6.1e-08.
