We divide 740472 by 21
Let's see how many times 21 fits into 740472.

Going ahead to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 21

Let's proceed to step 2:
21 can be fit into 74 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 63 from 74 to get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 21

Let's proceed to step 3:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 105 away from 110, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 21

Let's proceed to step 4:
21 goes into 54 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 352.0
Deduct 42 from 54 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 21

Moving on to step 5:
If we divide 127 by 21, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 3526.0
If we subtract 126 from 127, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 21

Going ahead to step 6:
The number 21 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 35260.0
If we subtract 0 from 12, 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.

Moving on to step 7:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 35260.5
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 35260.57
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 35260.571
Subtract 21 from 30 to 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.

Step 10:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 35260.5714
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.

Going ahead to step 11:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 35260.57142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 35260.571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 35260.5714285
If we take 105 away from 120, we end up 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 14:
If we divide 150 by 21, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 35260.57142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 35260.57142857 and a remainder of 3e-09.
