741276 ÷ 21 
We're looking to find how many times 21 goes into 741276.

Advancing to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 21

On to step 2:
When dividing 74 by 21, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 74, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 21

Going ahead to step 3:
When dividing 111 by 21, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 105 from 111 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Moving on to step 4:
When dividing 62 by 21, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 352.0
Deduct 42 from 62 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 21

Let's proceed to step 5:
207 divided by 21 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 3529.0
Deduct 189 from 207 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 21

Let's proceed to step 6:
When dividing 186 by 21, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 35298.0
If we take 168 away from 186, 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.

Step 7:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 35298.8
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.

Moving on to step 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35298.85
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 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 35298.857
If we take 147 away from 150, we end up 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.

Let's proceed to step 10:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 35298.8571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 35298.85714
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.

Let's proceed to step 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 35298.857142
Deduct 42 from 60 and we're left 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.

Going ahead to step 13:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 35298.8571428
Subtract 168 from 180 to 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.

Step 14:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 35298.85714285
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.

The quotient of the division is 35298.85714285, and the remainder is 1.5e-08.
