Let's divide 629570 by 21
Let's see how many times 21 fits into 629570.

Going ahead to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 21

Moving on to step 2:
21 goes into 62 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 21

Step 3:
209 divided by 21 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 189 from 209 to get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 21

Advancing to step 4:
21 can be fit into 205 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 299.0
The remainder is 16 after subtracting 189 from 205.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 21

Let's proceed to step 5:
When dividing 167 by 21, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 2997.0
Subtracting 147 from 167 leaves us with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 21

Advancing to step 6:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 29979.0
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.

Moving on to step 7:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 29979.5
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 21 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 29979.52
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 29979.523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 29979.5238
Deduct 168 from 170 and we're left 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 11:
20 divided by 21 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 29979.5238
Deduct 0 from 20 and we're left 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.

Step 12:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 29979.523809
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.

Going ahead to step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 29979.5238095
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.

Going ahead to step 14:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 29979.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 29979.52380952, and the remainder is 8e-09.
