We look at the division of 323536 by 21 
We're looking to find how many times 21 goes into 323536.

Moving on to 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

Let's proceed to step 2:
When dividing 32 by 21, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 21 from 32, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 21

Step 3:
21 goes into 113 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 105 from 113 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 21

Going ahead to step 4:
If we divide 85 by 21, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Subtract 84 from 85 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 21

Let's proceed to step 5:
When dividing 13 by 21, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 1540.0
Subtract 0 from 13 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 21

Step 6:
136 divided by 21 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 15406.0
Subtracting 126 from 136 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 15406.4
Subtracting 84 from 100 leaves us 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.

Going ahead to step 8:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 15406.47
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.

Let's proceed to step 9:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15406.476
If we take 126 away from 130, we end up 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.

Advancing to step 10:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 15406.4761
If we take 21 away from 40, we end up with 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 11:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 15406.47619
Subtracting 189 from 190 leaves us with 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 12:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15406.47619
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.

Advancing to step 13:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 15406.4761904
Deduct 84 from 100 and we're left 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.

Going ahead to step 14:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 15406.47619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 15406.47619047, with a leftover of 1.3e-08.
