We look at the division of 767553 by 21 
We want to figure out the number of times 767553 can be divided by 21.

Moving on to step 1:
7 divided by 21 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 21

Step 2:
The number 21 fits into 76 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 63 from 76, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 21

On to step 3:
21 goes into 137 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 126 from 137, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 21

Let's proceed to step 4:
If we divide 115 by 21, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 365.0
The remainder is 10 after subtracting 105 from 115.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 21

Step 5:
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: 3655.0
The remainder is 0 after subtracting 105 from 105.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 21

Moving on to step 6:
3 divided by 21 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 36550.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 36550.1
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 36550.14
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 36550.142
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
If we divide 180 by 21, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 36550.1428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 36550.14285
Deduct 105 from 120 and we're left 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.

Moving on to step 12:
150 divided by 21 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 36550.142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 36550.1428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 36550.14285714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 36550.14285714, and the remainder is 6e-09.
