645465 ÷ 55 
We want to figure out the number of times 645465 can be divided by 55.

Moving on to step 1:
55 can be fit into 6 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 55

Moving on to step 2:
When dividing 64 by 55, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 55 from 64, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 55

Let's proceed to step 3:
95 divided by 55 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 40 after subtracting 55 from 95.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 55

On to step 4:
55 can be fit into 404 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 117.0
Subtracting 385 from 404 leaves us with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 55

Step 5:
55 can be fit into 196 3 times, resulting in a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
Subtract 165 from 196 to get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 55

On to step 6:
55 can be fit into 315 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 11735.0
If we take 275 away from 315, we end up 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 7:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 11735.7
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 8:
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: 11735.72
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.

Advancing to step 9:
55 goes into 400 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 11735.727
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.

Step 10:
When dividing 150 by 55, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 11735.7272
If we take 110 away from 150, we end up 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.

Going ahead to step 11:
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: 11735.72727
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.

On to step 12:
The number 55 fits into 150 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 11735.727272
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.

Let's proceed to step 13:
If we divide 400 by 55, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 11735.7272727
If we subtract 385 from 400, we 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.

Step 14:
150 divided by 55 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 11735.72727272
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.

The final result is 11735.72727272 with a remainder of 4e-08.
