85255570 ÷ 649 
Let's see how many times 649 fits into 85255570.

Let's proceed to step 1:
649 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 649

Advancing to step 2:
The number 649 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 649

Going ahead to step 3:
If we divide 852 by 649, we get 1 and a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 649 from 852, we get 203.
Fetch the next digit (5) from the dividend, attach it to 203 and continue: 2035 / 649

Let's proceed to step 4:
2035 divided by 649 is 3 with a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1947 from 2035 leaves us with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 649

On to step 5:
The number 649 fits into 885 1 times, leaving a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtract 649 from 885 to get 236.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 649

On to step 6:
When dividing 2365 by 649, we get 3 with a remainder of 418.
The next digit of our result is 3. 
Result so far: 1313.0
If we subtract 1947 from 2365, we get 418.
Bring next digit (7) of the dividend behind the 418 and repeat the process: 4187 / 649

Let's proceed to step 7:
649 goes into 4187 6 times with a remainder of 293.
Write down 6 as next digit of the result. 
Result so far: 13136.0
Subtracting 3894 from 4187 leaves us with 293.
Include the next digit (0) from the dividend after 293, then repeat: 2930 / 649

On to step 8:
2930 divided by 649 is 4 with a remainder of 334.
Use 4 as the next digit of our solution. 
Result so far: 131364.0
Subtract 2596 from 2930 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
649 can be fit into 3340 5 times, resulting in a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 131364.5
If we subtract 3245 from 3340, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
The number 649 fits into 950 1 times, leaving a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 131364.51
The remainder is 301 after subtracting 649 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 11:
649 goes into 3010 4 times with a remainder of 414.
The number 4 becomes the next digit in our result. 
Result so far: 131364.514
Subtract 2596 from 3010 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 12:
The number 649 fits into 4140 6 times, leaving a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 131364.5146
Deduct 3894 from 4140 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 13:
The number 649 fits into 2460 3 times, leaving a remainder of 513.
The next digit of our result is 3. 
Result so far: 131364.51463
If we subtract 1947 from 2460, we get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 14:
5130 divided by 649 is 7 with a remainder of 587.
Put 7 as the next digit of the answer. 
Result so far: 131364.514637
The remainder is 587 after subtracting 4543 from 5130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 15:
If we divide 5870 by 649, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 131364.5146379
Subtract 5841 from 5870 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 16:
649 can be fit into 290 0 times, resulting in a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 131364.5146379
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final result is 131364.5146379 with a remainder of 2.9e-07.
