We're dividing 162936 by 21 
We want to divide 162936 by 21.

Going ahead to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Let's proceed to step 2:
21 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 21

Advancing to step 3:
If we divide 162 by 21, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 15 after subtracting 147 from 162.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 21

Going ahead to step 4:
21 can be fit into 159 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 12 after subtracting 147 from 159.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 21

Let's proceed to step 5:
123 divided by 21 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 775.0
Subtract 105 from 123 to get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Moving on to step 6:
If we divide 186 by 21, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 7758.0
If we take 168 away from 186, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7758.8
The remainder is 12 after subtracting 168 from 180.
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 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7758.85
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.

Advancing to step 9:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7758.857
Subtract 147 from 150 to 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.

Step 10:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7758.8571
If we take 21 away from 30, we end up 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.

On to step 11:
90 divided by 21 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 7758.85714
Subtracting 84 from 90 leaves us with 6.
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 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 7758.857142
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.

On to step 13:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 7758.8571428
Subtracting 168 from 180 leaves us 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 14:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7758.85714285
If we take 105 away from 120, we end up 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.

The final result is 7758.85714285 with a remainder of 1.5e-08.
