Let's divide 703998 by 21
Our goal is to divide 703998 by 21.

Step 1:
7 divided by 21 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Step 2:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 63 from 70 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Moving on to step 3:
If we divide 73 by 21, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 63 from 73 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 21

On to step 4:
The number 21 fits into 109 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 335.0
If we subtract 105 from 109, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 21

Going ahead to step 5:
21 goes into 49 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 3352.0
Subtracting 42 from 49 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 21

Step 6:
If we divide 78 by 21, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 33523.0
The remainder is 15 after subtracting 63 from 78.
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 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 33523.7
Subtracting 147 from 150 leaves us 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 8:
If we divide 30 by 21, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 33523.71
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.

Let's proceed to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 33523.714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 33523.7142
Subtract 42 from 60 to 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.

Moving on to step 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33523.71428
Deduct 168 from 180 and we're left 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.

Step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 33523.714285
If we take 105 away from 120, we end up 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.

Advancing to step 13:
150 divided by 21 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 33523.7142857
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 14:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 33523.71428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 33523.71428571 with a balance of 9e-09.
