Let's divide 45805379 by 309
Our goal is to divide 45805379 by 309.

Let's proceed to step 1:
If we divide 4 by 309, we get 0 and 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.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 309

Going ahead to step 2:
When dividing 45 by 309, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 309

On to step 3:
458 divided by 309 is 1 with a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 309 from 458, we get 149.
Fetch the next digit (0) from the dividend, attach it to 149 and continue: 1490 / 309

Going ahead to step 4:
309 can be fit into 1490 4 times, resulting in a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 254 after subtracting 1236 from 1490.
Append the next digit (5) from the dividend to 254 and continue with: 2545 / 309

Step 5:
309 goes into 2545 8 times with a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 148.0
The remainder is 73 after subtracting 2472 from 2545.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 309

On to step 6:
309 can be fit into 733 2 times, resulting in a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 1482.0
Subtracting 618 from 733 leaves us with 115.
Take the next digit (7) from the dividend and append it to 115, then repeat: 1157 / 309

Advancing to step 7:
When dividing 1157 by 309, we get 3 with a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 14823.0
Subtracting 927 from 1157 leaves us with 230.
Append the next digit (9) from the dividend to 230 and continue with: 2309 / 309

Advancing to step 8:
2309 divided by 309 is 7 with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 148237.0
The remainder is 146 after subtracting 2163 from 2309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
1460 divided by 309 is 4 with a remainder of 224.
The next digit of our result is 4. 
Result so far: 148237.4
Subtract 1236 from 1460 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
2240 divided by 309 is 7 with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 148237.47
If we take 2163 away from 2240, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
When dividing 770 by 309, we get 2 with a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 148237.472
The remainder is 152 after subtracting 618 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
1520 divided by 309 is 4 with a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 148237.4724
Deduct 1236 from 1520 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 13:
309 goes into 2840 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 148237.47249
If we take 2781 away from 2840, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
309 can be fit into 590 1 times, resulting in a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 148237.472491
If we subtract 309 from 590, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 15:
When dividing 2810 by 309, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 148237.4724919
If we subtract 2781 from 2810, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 16:
309 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 148237.4724919
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 148237.4724919, with a leftover of 2.9e-07.
