766534 ÷ 21 
We want to figure out the number of times 766534 can be divided by 21.

Let's proceed to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 21

Advancing to step 2:
76 divided by 21 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 63 from 76 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 21

Let's proceed to step 3:
When dividing 136 by 21, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 126 from 136 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 21

Let's proceed to step 4:
21 can be fit into 105 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 365.0
If we subtract 105 from 105, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 21

Advancing to step 5:
21 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 3650.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 21

Let's proceed to step 6:
34 divided by 21 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 36501.0
Deduct 21 from 34 and we're left 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.

On to step 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 36501.6
The remainder is 4 after subtracting 126 from 130.
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 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 36501.61
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 36501.619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 36501.619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 36501.61904
If we take 84 away from 100, we end up 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.

Let's proceed to step 12:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 36501.619047
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.

Moving on to step 13:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 36501.6190476
If we subtract 126 from 130, we 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.

Step 14:
21 goes into 40 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 36501.61904761
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.

The quotient of the division is 36501.61904761, and the remainder is 1.9e-08.
