90347387 ÷ 717 
We want to figure out the number of times 90347387 can be divided by 717.

Step 1:
9 divided by 717 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 717

Step 2:
90 divided by 717 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 717

Going ahead to step 3:
717 can be fit into 903 1 times, resulting in a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 717 away from 903, we end up with 186.
Bring next digit (4) of the dividend behind the 186 and repeat the process: 1864 / 717

On to step 4:
If we divide 1864 by 717, we get 2 and a remainder of 430.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 430 after subtracting 1434 from 1864.
Take the next digit (7) from the dividend and append it to 430, then repeat: 4307 / 717

Step 5:
717 can be fit into 4307 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 4302 from 4307 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 717

Let's proceed to step 6:
If we divide 53 by 717, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 717

Step 7:
538 divided by 717 is 0 with a remainder of 538.
Record the quotient 0 as the next digit in the result. 
Result so far: 12600.0
If we subtract 0 from 538, we get 538.
Take the next digit (7) from the dividend and append it to 538, then repeat: 5387 / 717

Step 8:
717 goes into 5387 7 times with a remainder of 368.
The number 7 becomes the next digit in our result. 
Result so far: 126007.0
If we take 5019 away from 5387, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 9:
717 goes into 3680 5 times with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 126007.5
Subtracting 3585 from 3680 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 10:
When dividing 950 by 717, we get 1 with a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 126007.51
Subtracting 717 from 950 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 11:
2330 divided by 717 is 3 with a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 126007.513
Subtracting 2151 from 2330 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 12:
When dividing 1790 by 717, we get 2 with a remainder of 356.
Put 2 as the next digit of the answer. 
Result so far: 126007.5132
If we take 1434 away from 1790, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 13:
717 goes into 3560 4 times with a remainder of 692.
Write down 4 as next digit of the result. 
Result so far: 126007.51324
If we take 2868 away from 3560, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

On to step 14:
When dividing 6920 by 717, we get 9 with a remainder of 467.
Record the quotient 9 as the next digit in the result. 
Result so far: 126007.513249
If we take 6453 away from 6920, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 15:
The number 717 fits into 4670 6 times, leaving a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 126007.5132496
If we subtract 4302 from 4670, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 16:
3680 divided by 717 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 126007.51324965
Deduct 3585 from 3680 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Our division results in 126007.51324965 with a remaining 9.5e-08.
