296947 divided by 21 
Our goal is to divide 296947 by 21.

Going ahead to step 1:
21 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 21

Step 2:
The number 21 fits into 29 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 21 from 29, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 21

Let's proceed to step 3:
If we divide 86 by 21, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 84 from 86 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 21

Advancing to step 4:
The number 21 fits into 29 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Deduct 21 from 29 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 21

Advancing to step 5:
If we divide 84 by 21, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
The remainder is 0 after subtracting 84 from 84.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 21

On to step 6:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 14140.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 21, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 14140.3
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 14140.33
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 14140.33, and the remainder is 0.007.
