35202 ÷ 21 
We want to divide 35202 by 21.

Step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 21

Advancing to step 2:
35 divided by 21 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 35 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 21

Let's proceed to step 3:
21 can be fit into 142 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 16 after subtracting 126 from 142.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 21

Let's proceed to step 4:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
If we take 147 away from 160, we end up with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 21

Moving on to step 5:
The number 21 fits into 132 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1676.0
The remainder is 6 after subtracting 126 from 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 6:
When dividing 60 by 21, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 1676.2
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.

Let's proceed to step 7:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1676.28
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 21 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1676.285
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.

Let's proceed to step 9:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1676.2857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1676.28571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 1676.285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1676.2857142
If we subtract 42 from 60, we 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.

Going ahead to step 13:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1676.28571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1676.28571428 with a remainder of 1.2e-08.
