We're dividing 699525 by 21 
Let's see how many times 21 fits into 699525.

On to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 21

Going ahead to step 2:
If we divide 69 by 21, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 63 from 69 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

Going ahead to step 3:
21 can be fit into 69 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 63 from 69, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 21

Let's proceed to step 4:
21 can be fit into 65 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 333.0
Deduct 63 from 65 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

Let's proceed to step 5:
When dividing 22 by 21, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3331.0
Subtracting 21 from 22 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 21

Advancing to step 6:
21 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 33310.0
The remainder is 15 after subtracting 0 from 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 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 33310.7
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 33310.71
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.

Step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 33310.714
If we take 84 away from 90, we end up 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.

Step 10:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 33310.7142
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.

Step 11:
21 goes into 180 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 33310.71428
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.

Let's proceed to step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 33310.714285
Subtracting 105 from 120 leaves us 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.

On to step 13:
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: 33310.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
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: 33310.71428571
If we subtract 21 from 30, we 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.

Our division results in 33310.71428571 with a remaining 9e-09.
