66438356 ÷ 273 
Let's see how many times 273 fits into 66438356.

On to step 1:
6 divided by 273 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 273

Advancing to step 2:
The number 273 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 273

Going ahead to step 3:
When dividing 664 by 273, we get 2 with a remainder of 118.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 546 from 664 and we're left with 118.
Take the next digit (3) from the dividend and append it to 118, then repeat: 1183 / 273

On to step 4:
273 can be fit into 1183 4 times, resulting in a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1092 from 1183 to get 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 273

Moving on to step 5:
273 can be fit into 918 3 times, resulting in a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 243.0
The remainder is 99 after subtracting 819 from 918.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 273

Advancing to step 6:
273 goes into 993 3 times with a remainder of 174.
The next digit of our result is 3. 
Result so far: 2433.0
Subtract 819 from 993 to get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 273

On to step 7:
The number 273 fits into 1745 6 times, leaving a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 24336.0
Deduct 1638 from 1745 and we're left with 107.
Grab the next digit (6) from the dividend, add it to 107, then carry on: 1076 / 273

Going ahead to step 8:
273 can be fit into 1076 3 times, resulting in a remainder of 257.
The number 3 becomes the next digit in our result. 
Result so far: 243363.0
If we subtract 819 from 1076, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 9:
When dividing 2570 by 273, we get 9 with a remainder of 113.
The next digit of our result is 9. 
Result so far: 243363.9
Subtracting 2457 from 2570 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 10:
If we divide 1130 by 273, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 243363.94
Deduct 1092 from 1130 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
When dividing 380 by 273, we get 1 with a remainder of 107.
The next digit of our result is 1. 
Result so far: 243363.941
If we take 273 away from 380, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 12:
1070 divided by 273 is 3 with a remainder of 251.
The next digit of our result is 3. 
Result so far: 243363.9413
If we take 819 away from 1070, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 13:
When dividing 2510 by 273, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 243363.94139
If we take 2457 away from 2510, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 14:
273 goes into 530 1 times with a remainder of 257.
Use 1 as the next digit of our solution. 
Result so far: 243363.941391
Subtracting 273 from 530 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 15:
When dividing 2570 by 273, we get 9 with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 243363.9413919
If we take 2457 away from 2570, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 16:
If we divide 1130 by 273, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 243363.94139194
Deduct 1092 from 1130 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 243363.94139194 with a remainder of 3.8e-08.
