740275 ÷ 21 
Let's see how many times 21 fits into 740275.

Advancing to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 21

Advancing to step 2:
21 can be fit into 74 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 63 away from 74, we end up with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 21

Advancing to step 3:
110 divided by 21 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 5 after subtracting 105 from 110.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 21

Advancing to step 4:
When dividing 52 by 21, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 352.0
The remainder is 10 after subtracting 42 from 52.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Step 5:
21 goes into 107 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 3525.0
The remainder is 2 after subtracting 105 from 107.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Going ahead to step 6:
21 goes into 25 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 35251.0
If we take 21 away from 25, we end up 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 7:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 35251.1
Subtracting 21 from 40 leaves us 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.

Step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 35251.19
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.

Let's proceed to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 35251.19
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 35251.1904
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 11:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 35251.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
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: 35251.190476
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.

Moving on to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 35251.1904761
Subtracting 21 from 40 leaves us 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.

Going ahead to step 14:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 35251.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 35251.19047619 with a remainder of 1e-09.
