Let's divide 38066291 by 21
Our goal is to divide 38066291 by 21.

On to step 1:
3 divided by 21 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Let's proceed to step 2:
21 can be fit into 38 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 38 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 21

On to step 3:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 2 after subtracting 168 from 170.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 21

Step 4:
When dividing 26 by 21, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 181.0
The remainder is 5 after subtracting 21 from 26.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

Moving on to step 5:
21 can be fit into 56 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1812.0
If we take 42 away from 56, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 21

Moving on to step 6:
If we divide 142 by 21, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 18126.0
Deduct 126 from 142 and we're left with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 21

Going ahead to step 7:
169 divided by 21 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 181268.0
The remainder is 1 after subtracting 168 from 169.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

Going ahead to step 8:
11 divided by 21 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 1812680.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1812680.5
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1812680.52
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 1812680.523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1812680.5238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1812680.5238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1812680.523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 15:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1812680.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1812680.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1812680.52380952, and the remainder is 8e-09.
