64528685 ÷ 550 
Let's see how many times 550 fits into 64528685.

Advancing to step 1:
6 divided by 550 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 550

Moving on to step 2:
If we divide 64 by 550, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 550

On to step 3:
The number 550 fits into 645 1 times, leaving a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 550 from 645 and we're left with 95.
Include the next digit (2) from the dividend after 95, then repeat: 952 / 550

Let's proceed to step 4:
550 goes into 952 1 times with a remainder of 402.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 550 from 952, we get 402.
Bring next digit (8) of the dividend behind the 402 and repeat the process: 4028 / 550

Advancing to step 5:
When dividing 4028 by 550, we get 7 with a remainder of 178.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 3850 from 4028 and we're left with 178.
Fetch the next digit (6) from the dividend, attach it to 178 and continue: 1786 / 550

Step 6:
1786 divided by 550 is 3 with a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 1173.0
Deduct 1650 from 1786 and we're left with 136.
Bring next digit (8) of the dividend behind the 136 and repeat the process: 1368 / 550

Step 7:
The number 550 fits into 1368 2 times, leaving a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 11732.0
Subtract 1100 from 1368 to get 268.
Grab the next digit (5) from the dividend, add it to 268, then carry on: 2685 / 550

Let's proceed to step 8:
550 can be fit into 2685 4 times, resulting in a remainder of 485.
Use 4 as the next digit of our solution. 
Result so far: 117324.0
Deduct 2200 from 2685 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 9:
550 can be fit into 4850 8 times, resulting in a remainder of 450.
The next digit of our result is 8. 
Result so far: 117324.8
If we take 4400 away from 4850, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
When dividing 4500 by 550, we get 8 with a remainder of 100.
The next digit of our result is 8. 
Result so far: 117324.88
Deduct 4400 from 4500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 117324.88 with a remainder of 0.1.
