We divide 163705 by 21
Our goal is to divide 163705 by 21.

Let's proceed to step 1:
1 divided by 21 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Moving on to step 2:
When dividing 16 by 21, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 21

Going ahead to step 3:
21 goes into 163 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 16 after subtracting 147 from 163.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 21

Step 4:
The number 21 fits into 167 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 147 from 167, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 21

Going ahead to step 5:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 779.0
If we take 189 away from 200, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 21

Let's proceed to step 6:
21 goes into 115 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7795.0
If we take 105 away from 115, we end up 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 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7795.4
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7795.47
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.

Step 9:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7795.476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 7795.4761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 7795.47619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7795.47619
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.

Let's proceed to step 13:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 7795.4761904
If we take 84 away from 100, we end up 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.

Step 14:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7795.47619047
If we take 147 away from 160, we end up with 13.
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 7795.47619047, with a leftover of 1.3e-08.
