We divide 993435 by 21
Our goal is to divide 993435 by 21.

Step 1:
21 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 21

Advancing to step 2:
21 goes into 99 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 84 from 99, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 21

Let's proceed to step 3:
If we divide 153 by 21, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 147 from 153, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

Let's proceed to step 4:
If we divide 64 by 21, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we take 63 away from 64, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 21

Moving on to step 5:
13 divided by 21 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 4730.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 21

Moving on to step 6:
21 goes into 135 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 47306.0
Subtract 126 from 135 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 47306.4
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 21, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 47306.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 47306.428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 47306.4285
Deduct 105 from 120 and we're left 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.

On to step 11:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 47306.42857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 47306.428571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
90 divided by 21 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 47306.4285714
Deduct 84 from 90 and we're left 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.

Let's proceed to step 14:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 47306.42857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 47306.42857142 with a remaining 1.8e-08.
