21193659 ÷ 273 
We're looking to find how many times 273 goes into 21193659.

Moving on to step 1:
273 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 273

Step 2:
273 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 273

Step 3:
The number 273 fits into 211 0 times, leaving a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Append the next digit (9) from the dividend to 211 and continue with: 2119 / 273

Let's proceed to step 4:
If we divide 2119 by 273, we get 7 and a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 1911 from 2119, we get 208.
Include the next digit (3) from the dividend after 208, then repeat: 2083 / 273

Moving on to step 5:
If we divide 2083 by 273, we get 7 and a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 1911 from 2083 to get 172.
Bring next digit (6) of the dividend behind the 172 and repeat the process: 1726 / 273

Going ahead to step 6:
273 goes into 1726 6 times with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 776.0
If we take 1638 away from 1726, we end up with 88.
Grab the next digit (5) from the dividend, add it to 88, then carry on: 885 / 273

On to step 7:
273 goes into 885 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 7763.0
If we take 819 away from 885, we end up with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 273

Let's proceed to step 8:
The number 273 fits into 669 2 times, leaving a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 77632.0
Subtracting 546 from 669 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 9:
1230 divided by 273 is 4 with a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 77632.4
If we subtract 1092 from 1230, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
273 can be fit into 1380 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 77632.45
Subtracting 1365 from 1380 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
If we divide 150 by 273, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 77632.45
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
When dividing 1500 by 273, we get 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 77632.4505
The remainder is 135 after subtracting 1365 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
273 can be fit into 1350 4 times, resulting in a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 77632.45054
If we take 1092 away from 1350, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 14:
273 goes into 2580 9 times with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 77632.450549
If we take 2457 away from 2580, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 15:
The number 273 fits into 1230 4 times, leaving a remainder of 138.
The next digit of our result is 4. 
Result so far: 77632.4505494
Subtracting 1092 from 1230 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 16:
1380 divided by 273 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 77632.45054945
The remainder is 15 after subtracting 1365 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 77632.45054945, with a leftover of 1.5e-08.
