We're dividing 350595 by 21 
Our goal is to divide 350595 by 21.

Moving on to step 1:
3 divided by 21 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 21

Going ahead to step 2:
21 can be fit into 35 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 21 from 35 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 21

Moving on to step 3:
140 divided by 21 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 14 after subtracting 126 from 140.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 21

Advancing to step 4:
145 divided by 21 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Deduct 126 from 145 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 21

Advancing to step 5:
199 divided by 21 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 1669.0
If we subtract 189 from 199, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 21

Step 6:
When dividing 105 by 21, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16695.0
Subtracting 105 from 105 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 21, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16695.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16695.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 16695.0 with a balance of 0.0.
