Let's divide 802121 by 38
We want to figure out the number of times 802121 can be divided by 38.

Step 1:
When dividing 8 by 38, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 38

On to step 2:
If we divide 80 by 38, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 76 away from 80, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 38

Let's proceed to step 3:
38 can be fit into 42 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 38 from 42 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 38

Moving on to step 4:
When dividing 41 by 38, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
If we take 38 away from 41, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 38

Step 5:
When dividing 32 by 38, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 2110.0
Subtracting 0 from 32 leaves us with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 38

Advancing to step 6:
38 can be fit into 321 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 21108.0
Deduct 304 from 321 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
38 can be fit into 170 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 21108.4
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 38 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 21108.44
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 21108.44 and a remainder of 0.028.
