We divide 755449 by 21
Our goal is to divide 755449 by 21.

On to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 21

Advancing to step 2:
When dividing 75 by 21, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
If we take 63 away from 75, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 21

On to step 3:
When dividing 125 by 21, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 105 away from 125, we end up with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 21

Let's proceed to step 4:
When dividing 204 by 21, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 359.0
The remainder is 15 after subtracting 189 from 204.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

On to step 5:
The number 21 fits into 154 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 3597.0
Subtracting 147 from 154 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 21

On to step 6:
21 goes into 79 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 35973.0
Subtracting 63 from 79 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.

Step 7:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 35973.7
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.

Moving on to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 35973.76
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 35973.761
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.

Moving on to step 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 35973.7619
Subtract 189 from 190 to 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.

Advancing to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 35973.7619
Subtracting 0 from 10 leaves us 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 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 35973.761904
If we subtract 84 from 100, we get 16.
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 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 35973.7619047
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.

Moving on to step 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 35973.76190476
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.

The quotient of the division is 35973.76190476, and the remainder is 4e-09.
