221395 ÷ 21 
Let's see how many times 21 fits into 221395.

Moving on to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Moving on to step 2:
21 goes into 22 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 22 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 21

Let's proceed to step 3:
When dividing 11 by 21, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 21

Let's proceed to step 4:
If we divide 113 by 21, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we take 105 away from 113, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Moving on to step 5:
When dividing 89 by 21, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 1054.0
Subtract 84 from 89 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 21

On to step 6:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 10542.0
If we take 42 away from 55, 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.

Let's proceed to step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 10542.6
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.

Let's proceed to step 8:
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: 10542.61
Subtracting 21 from 40 leaves us 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.

Going ahead to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 10542.619
Subtracting 189 from 190 leaves us 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.

Step 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10542.619
Subtracting 0 from 10 leaves us 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.

Going ahead to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 10542.61904
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 12:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 10542.619047
Deduct 147 from 160 and we're left 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.

Going ahead to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 10542.6190476
If we subtract 126 from 130, we get 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 14:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 10542.61904761
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.

The quotient of the division is 10542.61904761, and the remainder is 1.9e-08.
