We look at the division of 98473 by 21 
We want to figure out the number of times 98473 can be divided by 21.

Moving on to step 1:
9 divided by 21 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 21

On to step 2:
21 goes into 98 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 84 from 98 leaves us with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 21

Let's proceed to step 3:
If we divide 144 by 21, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 126 from 144, we get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 21

On to step 4:
The number 21 fits into 187 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 468.0
Deduct 168 from 187 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

Advancing to step 5:
21 goes into 193 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 4689.0
Subtracting 189 from 193 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 4689.1
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4689.19
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4689.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4689.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 4689.19047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4689.190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 4689.1904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4689.19047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 4689.19047619 with a remaining 1e-09.
