769933 divided by 21 
Our goal is to divide 769933 by 21.

Moving on to step 1:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
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

Moving on to step 2:
21 goes into 76 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
If we take 63 away from 76, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 21

Advancing to step 3:
When dividing 139 by 21, we get 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 126 from 139, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

On to step 4:
When dividing 139 by 21, we get 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 366.0
If we subtract 126 from 139, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 21

Going ahead to step 5:
When dividing 133 by 21, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 3666.0
Subtract 126 from 133 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Let's proceed to step 6:
When dividing 73 by 21, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 36663.0
Deduct 63 from 73 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 36663.4
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 36663.47
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 36663.476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 36663.4761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 36663.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 36663.47619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 36663.4761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
When dividing 160 by 21, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 36663.47619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 36663.47619047, with a leftover of 1.3e-08.
