We're dividing 21019801 by 545 
We're looking to find how many times 545 goes into 21019801.

Let's proceed to step 1:
545 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 545

Going ahead to step 2:
When dividing 21 by 545, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 545

Step 3:
545 goes into 210 0 times with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Take the next digit (1) from the dividend and append it to 210, then repeat: 2101 / 545

Going ahead to step 4:
When dividing 2101 by 545, we get 3 with a remainder of 466.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1635 from 2101, we get 466.
Fetch the next digit (9) from the dividend, attach it to 466 and continue: 4669 / 545

Going ahead to step 5:
When dividing 4669 by 545, we get 8 with a remainder of 309.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 4360 from 4669 leaves us with 309.
Bring next digit (8) of the dividend behind the 309 and repeat the process: 3098 / 545

Moving on to step 6:
545 goes into 3098 5 times with a remainder of 373.
Use 5 as the next digit of our solution. 
Result so far: 385.0
Deduct 2725 from 3098 and we're left with 373.
Take the next digit (0) from the dividend and append it to 373, then repeat: 3730 / 545

Step 7:
3730 divided by 545 is 6 with a remainder of 460.
Put 6 as the next digit of the answer. 
Result so far: 3856.0
If we take 3270 away from 3730, we end up with 460.
Take the next digit (1) from the dividend and append it to 460, then repeat: 4601 / 545

Going ahead to step 8:
4601 divided by 545 is 8 with a remainder of 241.
Use 8 as the next digit of our solution. 
Result so far: 38568.0
Subtract 4360 from 4601 to get 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:
545 goes into 2410 4 times with a remainder of 230.
The number 4 becomes the next digit in our result. 
Result so far: 38568.4
Deduct 2180 from 2410 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
If we divide 2300 by 545, we get 4 and a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 38568.44
Deduct 2180 from 2300 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 38568.44 and a remainder of 0.12.
