We divide 256195 by 21
Our goal is to divide 256195 by 21.

Step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 21

Moving on to step 2:
The number 21 fits into 25 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 25, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

On to step 3:
The number 21 fits into 46 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 42 from 46 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 21

Going ahead to step 4:
21 can be fit into 41 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 21 away from 41, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 21

Let's proceed to step 5:
21 can be fit into 209 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 1219.0
If we take 189 away from 209, we end up with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 21

Let's proceed to step 6:
21 can be fit into 205 9 times, resulting in a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 12199.0
If we subtract 189 from 205, we 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.

Let's proceed to step 7:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 12199.7
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.

Step 8:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 12199.76
If we take 126 away from 130, we end up 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.

Going ahead to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 12199.761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 12199.7619
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.

On to step 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 12199.7619
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.

Let's proceed to step 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 12199.761904
Subtracting 84 from 100 leaves us 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 13:
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: 12199.7619047
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.

Moving on to step 14:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12199.76190476
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.

The quotient of the division is 12199.76190476, and the remainder is 4e-09.
