We're dividing 6696999 by 21 
Let's see how many times 21 fits into 6696999.

Let's proceed to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 21

Step 2:
21 can be fit into 66 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 63 from 66 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 21

Step 3:
If we divide 39 by 21, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 21 from 39 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 21

Moving on to step 4:
21 can be fit into 186 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 318.0
Subtracting 168 from 186 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 21

Going ahead to step 5:
189 divided by 21 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 3189.0
If we take 189 away from 189, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 21

Step 6:
21 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 31890.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 21

Going ahead to step 7:
If we divide 99 by 21, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 318904.0
If we subtract 84 from 99, 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.

Step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 318904.7
Subtracting 147 from 150 leaves us 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.

Advancing to step 9:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 318904.71
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 318904.714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 318904.7142
Subtracting 42 from 60 leaves us 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.

Moving on to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 318904.71428
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.

Advancing 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: 318904.714285
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.

Going ahead to step 14:
150 divided by 21 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 318904.7142857
Deduct 147 from 150 and we're left 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 15:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 318904.71428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 318904.71428571, and the remainder is 9e-09.
