We divide 16605036 by 21
Our goal is to divide 16605036 by 21.

Let's proceed to step 1:
1 divided by 21 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 21

Advancing to step 2:
When dividing 16 by 21, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 21

Let's proceed to step 3:
If we divide 166 by 21, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 147 away from 166, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 21

Going ahead to step 4:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 189 from 190 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 21

On to step 5:
21 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 790.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 21

Going ahead to step 6:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7907.0
Subtract 147 from 150 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 21

On to step 7:
When dividing 33 by 21, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 79071.0
The remainder is 12 after subtracting 21 from 33.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 21

Let's proceed to step 8:
If we divide 126 by 21, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 790716.0
Subtract 126 from 126 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 21, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 790716.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 21, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 790716.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 790716.0 with a remaining 0.0.
