Let's divide 420646 by 22
We want to divide 420646 by 22.

Step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 22

Advancing to step 2:
The number 22 fits into 42 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 22 from 42 to get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 22

Moving on to step 3:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 198 away from 200, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 22

Moving on to step 4:
When dividing 26 by 22, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
The remainder is 4 after subtracting 22 from 26.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 22

Let's proceed to step 5:
22 can be fit into 44 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1912.0
If we take 44 away from 44, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 22

Advancing to step 6:
The number 22 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 19120.0
Subtracting 0 from 6 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.

Going ahead to step 7:
60 divided by 22 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 19120.2
Subtracting 44 from 60 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 8:
22 goes into 160 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 19120.27
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
22 goes into 60 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 19120.272
If we subtract 44 from 60, we 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.

Going ahead to step 10:
When dividing 160 by 22, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 19120.2727
If we take 154 away from 160, 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.

Let's proceed to step 11:
If we divide 60 by 22, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19120.27272
If we subtract 44 from 60, we 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 12:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19120.272727
Subtract 154 from 160 to get 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 13:
When dividing 60 by 22, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 19120.2727272
Deduct 44 from 60 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.

Advancing to step 14:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 19120.27272727
If we take 154 away from 160, 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.

The final outcome is 19120.27272727, with a leftover of 6e-09.
