19958979 divided by 341 
The aim is to understand the frequency of 341 in 19958979.

Moving on to step 1:
341 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 341

On to step 2:
The number 341 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 341

Step 3:
If we divide 199 by 341, we get 0 and a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 199 leaves us with 199.
Bring next digit (5) of the dividend behind the 199 and repeat the process: 1995 / 341

Step 4:
1995 divided by 341 is 5 with a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1705 from 1995 to get 290.
Grab the next digit (8) from the dividend, add it to 290, then carry on: 2908 / 341

Moving on to step 5:
When dividing 2908 by 341, we get 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 2728 from 2908 leaves us with 180.
Take the next digit (9) from the dividend and append it to 180, then repeat: 1809 / 341

Let's proceed to step 6:
If we divide 1809 by 341, we get 5 and a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 585.0
If we subtract 1705 from 1809, we get 104.
Take the next digit (7) from the dividend and append it to 104, then repeat: 1047 / 341

Moving on to step 7:
If we divide 1047 by 341, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 5853.0
Deduct 1023 from 1047 and we're left with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 341

Step 8:
When dividing 249 by 341, we get 0 with a remainder of 249.
Use 0 as the next digit of our solution. 
Result so far: 58530.0
Deduct 0 from 249 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 9:
If we divide 2490 by 341, we get 7 and a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 58530.7
If we subtract 2387 from 2490, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 10:
If we divide 1030 by 341, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 58530.73
The remainder is 7 after subtracting 1023 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
The number 341 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 58530.73
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
700 divided by 341 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 58530.7302
The remainder is 18 after subtracting 682 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
341 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 58530.7302
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
341 goes into 1800 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 58530.730205
If we take 1705 away from 1800, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 15:
If we divide 950 by 341, we get 2 and a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 58530.7302052
Subtracting 682 from 950 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 16:
341 goes into 2680 7 times with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 58530.73020527
The remainder is 293 after subtracting 2387 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final outcome is 58530.73020527, with a leftover of 2.93e-07.
