665950 ÷ 55 
We want to divide 665950 by 55.

Going ahead to step 1:
6 divided by 55 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 55

On to step 2:
When dividing 66 by 55, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 55 from 66 leaves us with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 55

Going ahead to step 3:
55 goes into 115 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 110 from 115 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 55

On to step 4:
If we divide 59 by 55, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we take 55 away from 59, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 55

Let's proceed to step 5:
The number 55 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 1210.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 55

Going ahead to step 6:
55 goes into 450 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 12108.0
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
55 goes into 100 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 12108.1
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 12108.18
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 55, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 12108.181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
If we divide 450 by 55, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 12108.1818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 12108.18181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
When dividing 450 by 55, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 12108.181818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 55, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 12108.1818181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
If we divide 450 by 55, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 12108.18181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 12108.18181818, with a leftover of 1e-08.
