66593993 ÷ 319 
Our goal is to divide 66593993 by 319.

Moving on to step 1:
319 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 319

Step 2:
319 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 319

Step 3:
665 divided by 319 is 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 638 from 665 to get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 319

Advancing to step 4:
319 can be fit into 279 0 times, resulting in a remainder of 279.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 279 to get 279.
Include the next digit (3) from the dividend after 279, then repeat: 2793 / 319

Going ahead to step 5:
319 goes into 2793 8 times with a remainder of 241.
The next digit of our result is 8. 
Result so far: 208.0
If we take 2552 away from 2793, we end up with 241.
Take the next digit (9) from the dividend and append it to 241, then repeat: 2419 / 319

Moving on to step 6:
When dividing 2419 by 319, we get 7 with a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 2087.0
Subtract 2233 from 2419 to get 186.
Fetch the next digit (9) from the dividend, attach it to 186 and continue: 1869 / 319

Going ahead to step 7:
319 can be fit into 1869 5 times, resulting in a remainder of 274.
Use 5 as the next digit of our solution. 
Result so far: 20875.0
Deduct 1595 from 1869 and we're left with 274.
Include the next digit (3) from the dividend after 274, then repeat: 2743 / 319

Advancing to step 8:
319 goes into 2743 8 times with a remainder of 191.
Use 8 as the next digit of our solution. 
Result so far: 208758.0
If we take 2552 away from 2743, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 9:
319 can be fit into 1910 5 times, resulting in a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 208758.5
Subtract 1595 from 1910 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 10:
319 goes into 3150 9 times with a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 208758.59
Deduct 2871 from 3150 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 11:
The number 319 fits into 2790 8 times, leaving a remainder of 238.
Put 8 as the next digit of the answer. 
Result so far: 208758.598
Subtracting 2552 from 2790 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
If we divide 2380 by 319, we get 7 and a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 208758.5987
If we subtract 2233 from 2380, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 13:
The number 319 fits into 1470 4 times, leaving a remainder of 194.
The next digit of our result is 4. 
Result so far: 208758.59874
The remainder is 194 after subtracting 1276 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 14:
1940 divided by 319 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 208758.598746
Subtracting 1914 from 1940 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
When dividing 260 by 319, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 208758.598746
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
319 can be fit into 2600 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 208758.59874608
If we subtract 2552 from 2600, 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.

The final outcome is 208758.59874608, with a leftover of 4.8e-08.
