57816093 ÷ 306 
We want to figure out the number of times 57816093 can be divided by 306.

On to step 1:
The number 306 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 306

Moving on to step 2:
The number 306 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 306

Step 3:
306 goes into 578 1 times with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 306 away from 578, we end up with 272.
Append the next digit (1) from the dividend to 272 and continue with: 2721 / 306

Step 4:
306 goes into 2721 8 times with a remainder of 273.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 2448 from 2721 and we're left with 273.
Bring next digit (6) of the dividend behind the 273 and repeat the process: 2736 / 306

Advancing to step 5:
306 goes into 2736 8 times with a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 188.0
If we take 2448 away from 2736, we end up with 288.
Append the next digit (0) from the dividend to 288 and continue with: 2880 / 306

Going ahead to step 6:
306 goes into 2880 9 times with a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 1889.0
The remainder is 126 after subtracting 2754 from 2880.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 306

Advancing to step 7:
If we divide 1269 by 306, we get 4 and a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 18894.0
Subtract 1224 from 1269 to get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 306

On to step 8:
The number 306 fits into 453 1 times, leaving a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 188941.0
Subtracting 306 from 453 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 9:
306 goes into 1470 4 times with a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 188941.4
Deduct 1224 from 1470 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
When dividing 2460 by 306, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 188941.48
If we subtract 2448 from 2460, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
If we divide 120 by 306, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 188941.48
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
When dividing 1200 by 306, we get 3 with a remainder of 282.
The next digit of our result is 3. 
Result so far: 188941.4803
If we take 918 away from 1200, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 13:
2820 divided by 306 is 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 188941.48039
If we take 2754 away from 2820, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
When dividing 660 by 306, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 188941.480392
If we subtract 612 from 660, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 15:
306 goes into 480 1 times with a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 188941.4803921
Deduct 306 from 480 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
The number 306 fits into 1740 5 times, leaving a remainder of 210.
The next digit of our result is 5. 
Result so far: 188941.48039215
The remainder is 210 after subtracting 1530 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 188941.48039215, with a leftover of 2.1e-07.
