We look at the division of 19809130 by 146 
The aim is to understand the frequency of 146 in 19809130.

Step 1:
146 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 146

Going ahead to step 2:
The number 146 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 146

On to step 3:
198 divided by 146 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 146 from 198, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 146

Advancing to step 4:
The number 146 fits into 520 3 times, leaving a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 82 after subtracting 438 from 520.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 146

Step 5:
The number 146 fits into 829 5 times, leaving a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 730 away from 829, we end up with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 146

Step 6:
146 can be fit into 991 6 times, resulting in a remainder of 115.
Use 6 as the next digit of our solution. 
Result so far: 1356.0
Subtract 876 from 991 to get 115.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 146

On to step 7:
1153 divided by 146 is 7 with a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 13567.0
Subtract 1022 from 1153 to get 131.
Fetch the next digit (0) from the dividend, attach it to 131 and continue: 1310 / 146

On to step 8:
1310 divided by 146 is 8 with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 135678.0
Deduct 1168 from 1310 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
146 goes into 1420 9 times with a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 135678.9
Deduct 1314 from 1420 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
The number 146 fits into 1060 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 135678.97
If we take 1022 away from 1060, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
The number 146 fits into 380 2 times, leaving a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 135678.972
Subtracting 292 from 380 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
The number 146 fits into 880 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 135678.9726
Subtract 876 from 880 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 146 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 135678.9726
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
The number 146 fits into 400 2 times, leaving a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 135678.972602
If we take 292 away from 400, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 15:
146 can be fit into 1080 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 135678.9726027
The remainder is 58 after subtracting 1022 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
The number 146 fits into 580 3 times, leaving a remainder of 142.
The next digit of our result is 3. 
Result so far: 135678.97260273
If we take 438 away from 580, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

In conclusion, the division gives 135678.97260273 with a balance of 1.42e-07.
