Let's divide 757407 by 21
We want to divide 757407 by 21.

Step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 21

Let's proceed to step 2:
21 can be fit into 75 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 75 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 21

On to step 3:
When dividing 127 by 21, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 126 away from 127, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 21

Let's proceed to step 4:
21 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 360.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 21

On to step 5:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 3606.0
Subtract 126 from 140 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 21

Going ahead to step 6:
When dividing 147 by 21, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 36067.0
If we take 147 away from 147, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36067.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
21 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36067.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 36067.0 with a remainder of 0.0.
