We divide 445657 by 21
Let's see how many times 21 fits into 445657.

Going ahead to step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 21

Let's proceed to step 2:
The number 21 fits into 44 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 44 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 21

Step 3:
If we divide 25 by 21, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 21 away from 25, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Going ahead to step 4:
If we divide 46 by 21, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
Subtract 42 from 46 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

Let's proceed to step 5:
45 divided by 21 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2122.0
Deduct 42 from 45 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 21

Let's proceed to step 6:
37 divided by 21 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 21221.0
Subtract 21 from 37 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.

Advancing to step 7:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 21221.7
If we subtract 147 from 160, we 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 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 21221.76
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.

Going ahead to step 9:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 21221.761
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 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 21221.7619
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.

Going ahead to step 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21221.7619
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:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 21221.761904
Deduct 84 from 100 and we're left 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.

Let's proceed to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 21221.7619047
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.

Moving on to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 21221.76190476
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.

After the division, we end up with 21221.76190476 and a remainder of 4e-09.
