765293 ÷ 21 
We're looking to find how many times 21 goes into 765293.

Going ahead to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 21

On to step 2:
21 can be fit into 76 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 63 from 76 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 21

Going ahead to step 3:
21 goes into 135 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 126 from 135 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 21

Step 4:
When dividing 92 by 21, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 364.0
If we take 84 away from 92, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Going ahead to step 5:
When dividing 89 by 21, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 3644.0
The remainder is 5 after subtracting 84 from 89.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 21

Going ahead to step 6:
The number 21 fits into 53 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 36442.0
Subtract 42 from 53 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 36442.5
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 36442.52
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
21 goes into 80 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 36442.523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
170 divided by 21 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 36442.5238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 36442.5238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 36442.523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 36442.5238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 36442.52380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 36442.52380952, with a leftover of 8e-09.
