We look at the division of 646479 by 22 
Let's see how many times 22 fits into 646479.

Let's proceed to step 1:
22 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 22

Let's proceed to step 2:
The number 22 fits into 64 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 20 after subtracting 44 from 64.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 22

Going ahead to step 3:
The number 22 fits into 206 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 198 away from 206, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 22

Moving on to step 4:
If we divide 84 by 22, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 293.0
If we take 66 away from 84, we end up with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 22

Going ahead to step 5:
187 divided by 22 is 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 2938.0
If we subtract 176 from 187, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 22

Advancing to step 6:
If we divide 119 by 22, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 29385.0
The remainder is 9 after subtracting 110 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
22 can be fit into 90 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 29385.4
Subtracting 88 from 90 leaves us 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.

Step 8:
If we divide 20 by 22, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 29385.4
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
22 can be fit into 200 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 29385.409
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 29385.409
Subtract 0 from 20 to 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:
22 goes into 200 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 29385.40909
Deduct 198 from 200 and we're left 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.

Step 12:
22 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 29385.40909
Subtract 0 from 20 to 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 13:
If we divide 200 by 22, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 29385.4090909
Subtracting 198 from 200 leaves us 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.

On to step 14:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 29385.4090909
Subtract 0 from 20 to 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.

The final result is 29385.4090909 with a remainder of 2e-08.
