Let's divide 29769 by 21
Let's see how many times 21 fits into 29769.

On to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 21

On to step 2:
29 divided by 21 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 21 from 29 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 21

Going ahead to step 3:
21 can be fit into 87 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 84 from 87 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

Advancing to step 4:
The number 21 fits into 36 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 15 after subtracting 21 from 36.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 21

Going ahead to step 5:
The number 21 fits into 159 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 1417.0
Subtract 147 from 159 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.

Step 6:
120 divided by 21 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1417.5
Deduct 105 from 120 and we're left 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.

Advancing to step 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1417.57
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:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1417.571
If we take 21 away from 30, we end up 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 9:
90 divided by 21 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1417.5714
Subtracting 84 from 90 leaves us 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.

Advancing to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1417.57142
If we take 42 away from 60, we end up 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.

Step 11:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1417.571428
Deduct 168 from 180 and we're left with 12.
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 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1417.5714285
The remainder is 15 after subtracting 105 from 120.
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 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1417.57142857
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.

The quotient of the division is 1417.57142857, and the remainder is 3e-09.
