Let's divide 657163 by 21
We want to figure out the number of times 657163 can be divided by 21.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

Step 2:
If we divide 65 by 21, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 63 from 65 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 21

Step 3:
The number 21 fits into 27 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 21 from 27 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 21

Advancing to step 4:
When dividing 61 by 21, we get 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we subtract 42 from 61, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 21

Let's proceed to step 5:
21 goes into 196 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 3129.0
The remainder is 7 after subtracting 189 from 196.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 21

On to step 6:
When dividing 73 by 21, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 31293.0
Subtract 63 from 73 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 7:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 31293.4
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 31293.47
Subtracting 147 from 160 leaves us 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.

Advancing to step 9:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 31293.476
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.

Let's proceed 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: 31293.4761
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.

Moving on to step 11:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 31293.47619
Deduct 189 from 190 and we're left 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:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31293.47619
If we subtract 0 from 10, we 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:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 31293.4761904
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.

Advancing to step 14:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 31293.47619047
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.

In conclusion, the division gives 31293.47619047 with a balance of 1.3e-08.
