Let's divide 20898121 by 408
We're looking to find how many times 408 goes into 20898121.

Advancing to step 1:
408 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 408

Advancing to step 2:
When dividing 20 by 408, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 408

Going ahead to step 3:
When dividing 208 by 408, we get 0 with a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Fetch the next digit (9) from the dividend, attach it to 208 and continue: 2089 / 408

Going ahead to step 4:
The number 408 fits into 2089 5 times, leaving a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 49 after subtracting 2040 from 2089.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 408

Advancing to step 5:
If we divide 498 by 408, we get 1 and a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 90 after subtracting 408 from 498.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 408

Moving on to step 6:
When dividing 901 by 408, we get 2 with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 512.0
Subtract 816 from 901 to get 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 408

Going ahead to step 7:
The number 408 fits into 852 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 5122.0
Deduct 816 from 852 and we're left with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 408

On to step 8:
If we divide 361 by 408, we get 0 and a remainder of 361.
The number 0 becomes the next digit in our result. 
Result so far: 51220.0
Subtracting 0 from 361 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 9:
The number 408 fits into 3610 8 times, leaving a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 51220.8
If we take 3264 away from 3610, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
408 goes into 3460 8 times with a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 51220.88
Subtract 3264 from 3460 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 51220.88 and a remainder of 0.196.
