442626 divided by 21 
We want to figure out the number of times 442626 can be divided by 21.

Let's proceed to step 1:
4 divided by 21 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

On to step 2:
When dividing 44 by 21, we get 2 with 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.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 21

Moving on to step 3:
21 goes into 22 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 21 away from 22, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Step 4:
16 divided by 21 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Subtract 0 from 16 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 21

Let's proceed to step 5:
21 can be fit into 162 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 2107.0
If we take 147 away from 162, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 21

Moving on to step 6:
When dividing 156 by 21, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 21077.0
Deduct 147 from 156 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 21, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 21077.4
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 21077.42
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 21 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 21077.428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 21077.4285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 21 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 21077.42857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 21077.428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 21077.4285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 21077.42857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 21077.42857142 with a remaining 1.8e-08.
