We divide 48813301 by 309
The aim is to understand the frequency of 309 in 48813301.

Let's proceed to step 1:
309 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 309

On to step 2:
The number 309 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 309

Moving on to step 3:
The number 309 fits into 488 1 times, leaving a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 179 after subtracting 309 from 488.
Append the next digit (1) from the dividend to 179 and continue with: 1791 / 309

Let's proceed to step 4:
309 can be fit into 1791 5 times, resulting in a remainder of 246.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 1545 from 1791 leaves us with 246.
Append the next digit (3) from the dividend to 246 and continue with: 2463 / 309

Going ahead to step 5:
When dividing 2463 by 309, we get 7 with a remainder of 300.
The next digit of our result is 7. 
Result so far: 157.0
Subtracting 2163 from 2463 leaves us with 300.
Bring next digit (3) of the dividend behind the 300 and repeat the process: 3003 / 309

Let's proceed to step 6:
If we divide 3003 by 309, we get 9 and a remainder of 222.
Use 9 as the next digit of our solution. 
Result so far: 1579.0
Subtract 2781 from 3003 to get 222.
Fetch the next digit (0) from the dividend, attach it to 222 and continue: 2220 / 309

On to step 7:
If we divide 2220 by 309, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 15797.0
The remainder is 57 after subtracting 2163 from 2220.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 309

Step 8:
571 divided by 309 is 1 with a remainder of 262.
The next digit of our result is 1. 
Result so far: 157971.0
If we take 309 away from 571, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 9:
The number 309 fits into 2620 8 times, leaving a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 157971.8
Subtracting 2472 from 2620 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
1480 divided by 309 is 4 with a remainder of 244.
The number 4 becomes the next digit in our result. 
Result so far: 157971.84
If we take 1236 away from 1480, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
The number 309 fits into 2440 7 times, leaving a remainder of 277.
Put 7 as the next digit of the answer. 
Result so far: 157971.847
If we subtract 2163 from 2440, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 12:
2770 divided by 309 is 8 with a remainder of 298.
Use 8 as the next digit of our solution. 
Result so far: 157971.8478
If we take 2472 away from 2770, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 13:
When dividing 2980 by 309, we get 9 with a remainder of 199.
The next digit of our result is 9. 
Result so far: 157971.84789
Subtract 2781 from 2980 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 14:
If we divide 1990 by 309, we get 6 and a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 157971.847896
Subtract 1854 from 1990 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
309 goes into 1360 4 times with a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 157971.8478964
If we subtract 1236 from 1360, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 16:
When dividing 1240 by 309, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 157971.84789644
Subtract 1236 from 1240 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.

The final outcome is 157971.84789644, with a leftover of 4e-09.
