Let's divide 687449 by 55
We want to divide 687449 by 55.

Advancing to step 1:
55 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 55

Advancing to step 2:
55 goes into 68 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 55 from 68 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 55

Going ahead to step 3:
55 goes into 137 2 times with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 110 from 137 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 55

Going ahead to step 4:
55 goes into 274 4 times with a remainder of 54.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 220 from 274 to get 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 55

Advancing to step 5:
55 goes into 544 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
Subtract 495 from 544 to get 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 55

Going ahead to step 6:
The number 55 fits into 499 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 12499.0
The remainder is 4 after subtracting 495 from 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
55 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12499.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 55 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 12499.07
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 55 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 12499.072
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 12499.0727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
55 goes into 150 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 12499.07272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 12499.072727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 12499.0727272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 12499.07272727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 12499.07272727 and a remainder of 1.5e-08.
