49839415 ÷ 146 
The aim is to understand the frequency of 146 in 49839415.

Advancing to step 1:
When dividing 4 by 146, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 146

On to step 2:
146 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 146

Let's proceed to step 3:
146 can be fit into 498 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 438 from 498 leaves us with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 146

Let's proceed to step 4:
If we divide 603 by 146, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 584 from 603, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 146

Step 5:
146 goes into 199 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 341.0
Deduct 146 from 199 and we're left with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 146

Going ahead to step 6:
If we divide 534 by 146, we get 3 and a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 3413.0
If we take 438 away from 534, we end up with 96.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 146

Let's proceed to step 7:
961 divided by 146 is 6 with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 34136.0
The remainder is 85 after subtracting 876 from 961.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 146

Step 8:
146 goes into 855 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 341365.0
Subtract 730 from 855 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
146 can be fit into 1250 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 341365.8
Subtracting 1168 from 1250 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
146 goes into 820 5 times with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 341365.85
If we take 730 away from 820, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 11:
The number 146 fits into 900 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 341365.856
The remainder is 24 after subtracting 876 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
240 divided by 146 is 1 with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 341365.8561
Subtract 146 from 240 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 13:
940 divided by 146 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 341365.85616
The remainder is 64 after subtracting 876 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
When dividing 640 by 146, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 341365.856164
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 15:
146 goes into 560 3 times with a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 341365.8561643
If we take 438 away from 560, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 16:
146 goes into 1220 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 341365.85616438
Subtract 1168 from 1220 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 341365.85616438, with a leftover of 5.2e-08.
