We divide 644900 by 55
Our goal is to divide 644900 by 55.

Step 1:
The number 55 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 55

Going ahead to step 2:
55 goes into 64 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 55 away from 64, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 55

Going ahead to step 3:
The number 55 fits into 94 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 55 from 94, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 55

Moving on to step 4:
55 can be fit into 399 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Deduct 385 from 399 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 55

Step 5:
55 can be fit into 140 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 1172.0
The remainder is 30 after subtracting 110 from 140.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 55

Step 6:
55 can be fit into 300 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 11725.0
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
250 divided by 55 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 11725.4
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11725.45
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 11725.454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
55 goes into 300 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11725.4545
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
If we divide 250 by 55, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 11725.45454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 55, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11725.454545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
When dividing 250 by 55, we get 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 11725.4545454
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11725.45454545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 11725.45454545 and a remainder of 2.5e-08.
