We're dividing 325943 by 21 
We're looking to find how many times 21 goes into 325943.

Let's proceed to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 21

Step 2:
When dividing 32 by 21, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 32 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 21

Advancing to step 3:
21 goes into 115 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 105 from 115 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 21

On to step 4:
21 can be fit into 109 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 155.0
Subtracting 105 from 109 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

On to step 5:
21 goes into 44 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1552.0
Subtracting 42 from 44 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 21

On to step 6:
21 goes into 23 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 15521.0
Subtract 21 from 23 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15521.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 15521.09
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15521.095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 15521.0952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 15521.09523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15521.095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
If we divide 20 by 21, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15521.095238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 15521.09523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 15521.09523809, and the remainder is 1.1e-08.
