We divide 446612 by 21
We're looking to find how many times 21 goes into 446612.

Advancing to step 1:
21 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Going ahead to step 2:
44 divided by 21 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 42 from 44, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 21

Step 3:
26 divided by 21 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 21 from 26 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 21

Let's proceed to step 4:
If we divide 56 by 21, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
Subtract 42 from 56 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 21

Going ahead to step 5:
If we divide 141 by 21, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 2126.0
Subtract 126 from 141 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 21

Moving on to step 6:
21 can be fit into 152 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 21267.0
Subtract 147 from 152 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 21267.2
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 21267.23
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 21267.238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 21267.238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 21267.23809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21267.238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 21267.2380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 21267.23809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 21267.23809523, with a leftover of 1.7e-08.
