We're dividing 301996 by 21 
We want to divide 301996 by 21.

Moving on to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 21

Let's proceed to step 2:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 21 from 30, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 21

Let's proceed to step 3:
When dividing 91 by 21, we get 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 84 from 91, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 21

Moving on to step 4:
21 goes into 79 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 143.0
If we take 63 away from 79, we end up with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 21

Advancing to step 5:
169 divided by 21 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 1438.0
If we subtract 168 from 169, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 21

Let's proceed to step 6:
16 divided by 21 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 14380.0
Deduct 0 from 16 and we're left 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.

Let's proceed to step 7:
If we divide 160 by 21, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 14380.7
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 14380.76
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 14380.761
If we take 21 away from 40, we end up 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.

Let's proceed to step 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 14380.7619
Subtracting 189 from 190 leaves us 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.

Let's proceed to step 11:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14380.7619
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 12:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 14380.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 14380.7619047
Subtract 147 from 160 to 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.

Moving on to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 14380.76190476
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.

After the division, we end up with 14380.76190476 and a remainder of 4e-09.
