21573 ÷ 98 
We're looking to find how many times 98 goes into 21573.

On to step 1:
When dividing 2 by 98, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 98

Let's proceed to step 2:
98 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 98

Going ahead to step 3:
98 can be fit into 215 2 times, resulting in a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
If we take 196 away from 215, we end up with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 98

On to step 4:
If we divide 197 by 98, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 1 after subtracting 196 from 197.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 98

Advancing to step 5:
The number 98 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 6:
130 divided by 98 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 220.1
The remainder is 32 after subtracting 98 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
320 divided by 98 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 220.13
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 98 fits into 260 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 220.132
The remainder is 64 after subtracting 196 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
640 divided by 98 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 220.1326
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
98 can be fit into 520 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 220.13265
Deduct 490 from 520 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
98 can be fit into 300 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 220.132653
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
60 divided by 98 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 220.132653
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
98 goes into 600 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 220.13265306
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 220.13265306 with a remainder of 1.2e-08.
