We're dividing 629306 by 21 
We want to figure out the number of times 629306 can be divided by 21.

Going ahead to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

Let's proceed to step 2:
62 divided by 21 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 42 from 62 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 21

On to step 3:
If we divide 209 by 21, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 189 from 209 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 21

Let's proceed to step 4:
21 goes into 203 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 299.0
The remainder is 14 after subtracting 189 from 203.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

Let's proceed to step 5:
When dividing 140 by 21, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 2996.0
If we subtract 126 from 140, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 21

Moving on to step 6:
146 divided by 21 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 29966.0
Subtracting 126 from 146 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 29966.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 29966.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 29966.952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 29966.9523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 29966.95238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 29966.95238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 29966.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 29966.95238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 29966.95238095, and the remainder is 5e-09.
