Let's divide 32541 by 21
Our goal is to divide 32541 by 21.

On to step 1:
If we divide 3 by 21, we get 0 and 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

Moving on to step 2:
If we divide 32 by 21, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 21 away from 32, we end up with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 21

Step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 105 from 115 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 21

On to step 4:
When dividing 104 by 21, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
The remainder is 20 after subtracting 84 from 104.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 21

On to step 5:
201 divided by 21 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 1549.0
Deduct 189 from 201 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 6:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1549.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1549.57
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:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1549.571
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.

Step 9:
21 goes into 90 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1549.5714
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.

Going ahead to step 10:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1549.57142
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.

Advancing to step 11:
21 goes into 180 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1549.571428
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.

Going ahead to step 12:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1549.5714285
Deduct 105 from 120 and we're left 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.

Going ahead to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1549.57142857
If we take 147 away from 150, we end up 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.

The final result is 1549.57142857 with a remainder of 3e-09.
