We're dividing 989349 by 21 
We want to figure out the number of times 989349 can be divided by 21.

Going ahead to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 21

On to step 2:
21 goes into 98 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 84 from 98, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 21

Advancing to step 3:
21 goes into 149 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 147 from 149 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 21

Going ahead to step 4:
When dividing 23 by 21, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
The remainder is 2 after subtracting 21 from 23.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 21

Advancing to step 5:
21 can be fit into 24 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4711.0
Deduct 21 from 24 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 21

Advancing to step 6:
39 divided by 21 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 47111.0
The remainder is 18 after subtracting 21 from 39.
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 7:
When dividing 180 by 21, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 47111.8
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 47111.85
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 47111.857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 47111.8571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 47111.85714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 47111.857142
If we subtract 42 from 60, we get 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 13:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 47111.8571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 47111.85714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 47111.85714285 with a remainder of 1.5e-08.
