Let's divide 645904 by 55
Our goal is to divide 645904 by 55.

On to step 1:
6 divided by 55 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 55

Step 2:
The number 55 fits into 64 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 55 from 64 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 55

On to step 3:
95 divided by 55 is 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 55 from 95, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 55

Let's proceed to step 4:
55 can be fit into 409 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we take 385 away from 409, we end up with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 55

Let's proceed to step 5:
If we divide 240 by 55, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 1174.0
The remainder is 20 after subtracting 220 from 240.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 55

Step 6:
55 goes into 204 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 11743.0
If we subtract 165 from 204, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 55 fits into 390 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 11743.7
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 55, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 11743.7
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
55 goes into 500 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 11743.709
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11743.709
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 11743.70909
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
When dividing 50 by 55, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11743.70909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 55, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 11743.7090909
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 55, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11743.7090909
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 11743.7090909 and a remainder of 5e-08.
