We're dividing 90864298 by 309 
We want to figure out the number of times 90864298 can be divided by 309.

On to step 1:
9 divided by 309 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 309

Step 2:
When dividing 90 by 309, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 309

Moving on to step 3:
908 divided by 309 is 2 with a remainder of 290.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 618 from 908, we get 290.
Bring next digit (6) of the dividend behind the 290 and repeat the process: 2906 / 309

Let's proceed to step 4:
When dividing 2906 by 309, we get 9 with a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 2781 from 2906 leaves us with 125.
Take the next digit (4) from the dividend and append it to 125, then repeat: 1254 / 309

Let's proceed to step 5:
The number 309 fits into 1254 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
Deduct 1236 from 1254 and we're left with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 309

Let's proceed to step 6:
309 goes into 182 0 times with a remainder of 182.
Put 0 as the next digit of the answer. 
Result so far: 2940.0
The remainder is 182 after subtracting 0 from 182.
Take the next digit (9) from the dividend and append it to 182, then repeat: 1829 / 309

Moving on to step 7:
When dividing 1829 by 309, we get 5 with a remainder of 284.
Record the quotient 5 as the next digit in the result. 
Result so far: 29405.0
If we take 1545 away from 1829, we end up with 284.
Include the next digit (8) from the dividend after 284, then repeat: 2848 / 309

Step 8:
When dividing 2848 by 309, we get 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 294059.0
Subtract 2781 from 2848 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
309 goes into 670 2 times with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 294059.2
The remainder is 52 after subtracting 618 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
309 can be fit into 520 1 times, resulting in a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 294059.21
Deduct 309 from 520 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
2110 divided by 309 is 6 with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 294059.216
Subtracting 1854 from 2110 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 12:
309 goes into 2560 8 times with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 294059.2168
If we subtract 2472 from 2560, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
309 can be fit into 880 2 times, resulting in a remainder of 262.
Write down 2 as next digit of the result. 
Result so far: 294059.21682
If we take 618 away from 880, 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.

Moving on to step 14:
When dividing 2620 by 309, we get 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 294059.216828
The remainder is 148 after subtracting 2472 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
309 can be fit into 1480 4 times, resulting in a remainder of 244.
Use 4 as the next digit of our solution. 
Result so far: 294059.2168284
Deduct 1236 from 1480 and we're left 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 16:
309 can be fit into 2440 7 times, resulting in a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 294059.21682847
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.

The final result is 294059.21682847 with a remainder of 2.77e-07.
