We're dividing 626938 by 21 
We want to figure out the number of times 626938 can be divided by 21.

Let's proceed to step 1:
21 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

Let's proceed to step 2:
21 can be fit into 62 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 42 from 62 and we're left with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 21

Going ahead to step 3:
21 can be fit into 206 9 times, resulting in a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 189 from 206 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Advancing to step 4:
21 goes into 179 8 times with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 298.0
The remainder is 11 after subtracting 168 from 179.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 21

Step 5:
21 can be fit into 113 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 2985.0
Deduct 105 from 113 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Let's proceed to step 6:
If we divide 88 by 21, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 29854.0
Deduct 84 from 88 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.

Going ahead to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 29854.1
If we subtract 21 from 40, we 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.

Going ahead to step 8:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 29854.19
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.

Step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 29854.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 29854.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 29854.19047
Subtract 147 from 160 to get 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:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 29854.190476
Subtracting 126 from 130 leaves us 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.

Moving on to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 29854.1904761
If we subtract 21 from 40, we 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.

Let's proceed to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 29854.19047619
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.

The final result is 29854.19047619 with a remainder of 1e-09.
