We're dividing 421021 by 22 
Let's see how many times 22 fits into 421021.

Going ahead to step 1:
22 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 22

Let's proceed to step 2:
When dividing 42 by 22, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 22 from 42 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 22

Moving on to step 3:
If we divide 201 by 22, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 3 after subtracting 198 from 201.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 22

Let's proceed to step 4:
22 can be fit into 30 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we subtract 22 from 30, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 22

Let's proceed to step 5:
22 goes into 82 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1913.0
Subtracting 66 from 82 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 22

Going ahead to step 6:
The number 22 fits into 161 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 19137.0
If we subtract 154 from 161, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 22 fits into 70 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 19137.3
If we take 66 away from 70, 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.

Step 8:
22 goes into 40 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 19137.31
Subtract 22 from 40 to 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.

Going ahead to step 9:
22 goes into 180 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 19137.318
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 22, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 19137.3181
The remainder is 18 after subtracting 22 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
180 divided by 22 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 19137.31818
Deduct 176 from 180 and we're left 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.

Step 12:
22 goes into 40 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19137.318181
Deduct 22 from 40 and we're left 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.

Moving on to step 13:
22 goes into 180 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 19137.3181818
The remainder is 4 after subtracting 176 from 180.
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:
22 goes into 40 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 19137.31818181
If we subtract 22 from 40, 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.

The quotient of the division is 19137.31818181, and the remainder is 1.8e-08.
