90097255 ÷ 647 
We want to figure out the number of times 90097255 can be divided by 647.

Going ahead to step 1:
If we divide 9 by 647, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 647

Advancing to step 2:
647 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 647

On to step 3:
The number 647 fits into 900 1 times, leaving a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 647 from 900 leaves us with 253.
Append the next digit (9) from the dividend to 253 and continue with: 2539 / 647

Moving on to step 4:
When dividing 2539 by 647, we get 3 with a remainder of 598.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1941 from 2539, we get 598.
Fetch the next digit (7) from the dividend, attach it to 598 and continue: 5987 / 647

Advancing to step 5:
If we divide 5987 by 647, we get 9 and a remainder of 164.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we take 5823 away from 5987, we end up with 164.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 647

Moving on to step 6:
647 can be fit into 1642 2 times, resulting in a remainder of 348.
The next digit of our result is 2. 
Result so far: 1392.0
Deduct 1294 from 1642 and we're left with 348.
Append the next digit (5) from the dividend to 348 and continue with: 3485 / 647

Going ahead to step 7:
When dividing 3485 by 647, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 13925.0
Subtract 3235 from 3485 to get 250.
Fetch the next digit (5) from the dividend, attach it to 250 and continue: 2505 / 647

Let's proceed to step 8:
647 goes into 2505 3 times with a remainder of 564.
The number 3 becomes the next digit in our result. 
Result so far: 139253.0
Subtract 1941 from 2505 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 9:
If we divide 5640 by 647, we get 8 and a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 139253.8
Deduct 5176 from 5640 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 10:
647 goes into 4640 7 times with a remainder of 111.
Record the quotient 7 as the next digit in the result. 
Result so far: 139253.87
If we subtract 4529 from 4640, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 11:
If we divide 1110 by 647, we get 1 and a remainder of 463.
Write down 1 as next digit of the result. 
Result so far: 139253.871
Deduct 647 from 1110 and we're left with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 12:
The number 647 fits into 4630 7 times, leaving a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 139253.8717
The remainder is 101 after subtracting 4529 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 13:
1010 divided by 647 is 1 with a remainder of 363.
Put 1 as the next digit of the answer. 
Result so far: 139253.87171
Subtracting 647 from 1010 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 14:
3630 divided by 647 is 5 with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 139253.871715
If we subtract 3235 from 3630, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 15:
When dividing 3950 by 647, we get 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 139253.8717156
Subtracting 3882 from 3950 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 16:
If we divide 680 by 647, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 139253.87171561
If we take 647 away from 680, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 139253.87171561 with a remainder of 3.3e-08.
