21501773 ÷ 838 
Our goal is to divide 21501773 by 838.

Advancing to step 1:
838 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
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 838

Moving on to step 2:
21 divided by 838 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 838

Step 3:
838 can be fit into 215 0 times, resulting in a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Include the next digit (0) from the dividend after 215, then repeat: 2150 / 838

Let's proceed to step 4:
2150 divided by 838 is 2 with a remainder of 474.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1676 from 2150 and we're left with 474.
Take the next digit (1) from the dividend and append it to 474, then repeat: 4741 / 838

Going ahead to step 5:
838 goes into 4741 5 times with a remainder of 551.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 4190 from 4741 and we're left with 551.
Append the next digit (7) from the dividend to 551 and continue with: 5517 / 838

Going ahead to step 6:
When dividing 5517 by 838, we get 6 with a remainder of 489.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
The remainder is 489 after subtracting 5028 from 5517.
Bring next digit (7) of the dividend behind the 489 and repeat the process: 4897 / 838

Advancing to step 7:
If we divide 4897 by 838, we get 5 and a remainder of 707.
Record the quotient 5 as the next digit in the result. 
Result so far: 2565.0
Subtracting 4190 from 4897 leaves us with 707.
Include the next digit (3) from the dividend after 707, then repeat: 7073 / 838

Going ahead to step 8:
7073 divided by 838 is 8 with a remainder of 369.
Record the quotient 8 as the next digit in the result. 
Result so far: 25658.0
Subtracting 6704 from 7073 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 9:
838 can be fit into 3690 4 times, resulting in a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 25658.4
Deduct 3352 from 3690 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 10:
838 can be fit into 3380 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 25658.44
Subtracting 3352 from 3380 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 25658.44 with a remaining 0.028.
