664745 divided by 55 
We want to figure out the number of times 664745 can be divided by 55.

Step 1:
If we divide 6 by 55, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 55

Moving 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
Deduct 55 from 66 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 55

Going ahead to step 3:
114 divided by 55 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 110 from 114 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 55

Going ahead to step 4:
When dividing 47 by 55, we get 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 47, we get 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 55

Step 5:
55 can be fit into 474 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1208.0
If we take 440 away from 474, we end up with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 55

Step 6:
If we divide 345 by 55, we get 6 and a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 12086.0
Subtract 330 from 345 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.

On to step 7:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 12086.2
Subtract 110 from 150 to 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.

Step 8:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 12086.27
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:
When dividing 150 by 55, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 12086.272
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.

Moving on to step 10:
When dividing 400 by 55, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 12086.2727
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.

Moving on to step 11:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 12086.27272
Deduct 110 from 150 and we're left 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.

On to step 12:
55 goes into 400 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 12086.272727
If we take 385 away from 400, we end up 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.

Advancing to step 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 12086.2727272
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 14:
55 goes into 400 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 12086.27272727
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.

The final outcome is 12086.27272727, with a leftover of 1.5e-08.
