329548 divided by 21 
We want to divide 329548 by 21.

Step 1:
3 divided by 21 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 21

Advancing to step 2:
If we divide 32 by 21, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 21 from 32 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 21

Step 3:
When dividing 119 by 21, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 105 from 119 and we're left with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 21

Moving on to step 4:
145 divided by 21 is 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 126 from 145 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 21

Step 5:
194 divided by 21 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1569.0
Deduct 189 from 194 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

Moving on to step 6:
When dividing 58 by 21, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 15692.0
The remainder is 16 after subtracting 42 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 15692.7
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 15692.76
Subtracting 126 from 130 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 9:
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: 15692.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15692.7619
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.

Advancing to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 15692.7619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 15692.761904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 15692.7619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 15692.76190476
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.

The final outcome is 15692.76190476, with a leftover of 4e-09.
