648520 ÷ 22 
We want to divide 648520 by 22.

Let's proceed to step 1:
6 divided by 22 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 22

Advancing to step 2:
64 divided by 22 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 44 from 64 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 22

Let's proceed to step 3:
If we divide 208 by 22, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 10 after subtracting 198 from 208.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 22

Moving on to step 4:
If we divide 105 by 22, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 294.0
Subtracting 88 from 105 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 22

Going ahead to step 5:
The number 22 fits into 172 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 2947.0
If we take 154 away from 172, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 22

Advancing to step 6:
180 divided by 22 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 29478.0
If we subtract 176 from 180, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
22 goes into 40 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 29478.1
If we take 22 away from 40, we end up 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.

Advancing to step 8:
180 divided by 22 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 29478.18
If we take 176 away from 180, 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.

Going ahead to step 9:
When dividing 40 by 22, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 29478.181
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.

Step 10:
22 goes into 180 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 29478.1818
Subtracting 176 from 180 leaves us 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.

Advancing to step 11:
40 divided by 22 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 29478.18181
If we take 22 away from 40, we end up 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.

Let's proceed to step 12:
If we divide 180 by 22, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 29478.181818
Subtract 176 from 180 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
When dividing 40 by 22, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 29478.1818181
If we take 22 away from 40, we end up 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.

On to step 14:
When dividing 180 by 22, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 29478.18181818
Subtracting 176 from 180 leaves us 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.

After the division, we end up with 29478.18181818 and a remainder of 4e-09.
