21033165 divided by 556 
Our goal is to divide 21033165 by 556.

Moving on to step 1:
556 goes into 2 0 times with 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 556

Advancing to step 2:
556 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 556

Step 3:
The number 556 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Take the next digit (3) from the dividend and append it to 210, then repeat: 2103 / 556

Moving on to step 4:
The number 556 fits into 2103 3 times, leaving a remainder of 435.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 435 after subtracting 1668 from 2103.
Fetch the next digit (3) from the dividend, attach it to 435 and continue: 4353 / 556

Let's proceed to step 5:
The number 556 fits into 4353 7 times, leaving a remainder of 461.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 3892 from 4353 to get 461.
Grab the next digit (1) from the dividend, add it to 461, then carry on: 4611 / 556

Moving on to step 6:
556 goes into 4611 8 times with a remainder of 163.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
If we take 4448 away from 4611, we end up with 163.
Take the next digit (6) from the dividend and append it to 163, then repeat: 1636 / 556

Going ahead to step 7:
When dividing 1636 by 556, we get 2 with a remainder of 524.
The next digit of our result is 2. 
Result so far: 3782.0
If we take 1112 away from 1636, we end up with 524.
Take the next digit (5) from the dividend and append it to 524, then repeat: 5245 / 556

On to step 8:
When dividing 5245 by 556, we get 9 with a remainder of 241.
The number 9 becomes the next digit in our result. 
Result so far: 37829.0
Subtracting 5004 from 5245 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 9:
556 goes into 2410 4 times with a remainder of 186.
Record the quotient 4 as the next digit in the result. 
Result so far: 37829.4
Subtract 2224 from 2410 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
1860 divided by 556 is 3 with a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 37829.43
If we take 1668 away from 1860, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
The number 556 fits into 1920 3 times, leaving a remainder of 252.
The number 3 becomes the next digit in our result. 
Result so far: 37829.433
If we take 1668 away from 1920, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 37829.433 with a remainder of 0.0252.
