Let's divide 522505 by 21
We want to figure out the number of times 522505 can be divided by 21.

Advancing to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 21

Moving on to step 2:
If we divide 52 by 21, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 10 after subtracting 42 from 52.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 21

Let's proceed to step 3:
21 can be fit into 102 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 84 from 102 to get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 21

Going ahead to step 4:
21 can be fit into 185 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtract 168 from 185 to get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 21

Going ahead to step 5:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 2488.0
If we subtract 168 from 170, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 21

Let's proceed to step 6:
When dividing 25 by 21, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 24881.0
The remainder is 4 after subtracting 21 from 25.
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 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 24881.1
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.

Advancing to step 8:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 24881.19
Subtract 189 from 190 to 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.

Advancing to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 24881.19
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 10:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 24881.1904
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.

Advancing to step 11:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 24881.19047
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.

Let's proceed to step 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 24881.190476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 24881.1904761
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.

Moving on to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 24881.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 24881.19047619 with a balance of 1e-09.
