We divide 621268 by 21
We're looking to find how many times 21 goes into 621268.

Going ahead to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Moving on to step 2:
When dividing 62 by 21, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 20 after subtracting 42 from 62.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 21

Going ahead to step 3:
When dividing 201 by 21, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 189 away from 201, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 21

Step 4:
21 can be fit into 122 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 295.0
Deduct 105 from 122 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 21

Step 5:
176 divided by 21 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2958.0
Deduct 168 from 176 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 21

Step 6:
21 goes into 88 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 29584.0
Subtract 84 from 88 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 29584.1
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29584.19
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 29584.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 29584.1904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 29584.19047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 29584.190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 29584.1904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 29584.19047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 29584.19047619, and the remainder is 1e-09.
