90312407 ÷ 517 
We want to divide 90312407 by 517.

Let's proceed to step 1:
517 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 517

Step 2:
The number 517 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 517

Moving on to step 3:
The number 517 fits into 903 1 times, leaving a remainder of 386.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 517 away from 903, we end up with 386.
Append the next digit (1) from the dividend to 386 and continue with: 3861 / 517

On to step 4:
517 goes into 3861 7 times with a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3619 from 3861 to get 242.
Take the next digit (2) from the dividend and append it to 242, then repeat: 2422 / 517

Going ahead to step 5:
If we divide 2422 by 517, we get 4 and a remainder of 354.
Put 4 as the next digit of the answer. 
Result so far: 174.0
Subtracting 2068 from 2422 leaves us with 354.
Include the next digit (4) from the dividend after 354, then repeat: 3544 / 517

On to step 6:
517 goes into 3544 6 times with a remainder of 442.
The number 6 becomes the next digit in our result. 
Result so far: 1746.0
Deduct 3102 from 3544 and we're left with 442.
Fetch the next digit (0) from the dividend, attach it to 442 and continue: 4420 / 517

Advancing to step 7:
If we divide 4420 by 517, we get 8 and a remainder of 284.
Record the quotient 8 as the next digit in the result. 
Result so far: 17468.0
Subtract 4136 from 4420 to get 284.
Fetch the next digit (7) from the dividend, attach it to 284 and continue: 2847 / 517

Advancing to step 8:
517 goes into 2847 5 times with a remainder of 262.
Record the quotient 5 as the next digit in the result. 
Result so far: 174685.0
If we take 2585 away from 2847, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
517 goes into 2620 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 174685.5
If we subtract 2585 from 2620, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
517 goes into 350 0 times with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 174685.5
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
When dividing 3500 by 517, we get 6 with a remainder of 398.
The next digit of our result is 6. 
Result so far: 174685.506
Deduct 3102 from 3500 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 12:
517 goes into 3980 7 times with a remainder of 361.
The next digit of our result is 7. 
Result so far: 174685.5067
The remainder is 361 after subtracting 3619 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 13:
517 goes into 3610 6 times with a remainder of 508.
Write down 6 as next digit of the result. 
Result so far: 174685.50676
The remainder is 508 after subtracting 3102 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 14:
When dividing 5080 by 517, we get 9 with a remainder of 427.
The next digit of our result is 9. 
Result so far: 174685.506769
If we take 4653 away from 5080, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Step 15:
When dividing 4270 by 517, we get 8 with a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 174685.5067698
Subtracting 4136 from 4270 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 16:
When dividing 1340 by 517, we get 2 with a remainder of 306.
Record the quotient 2 as the next digit in the result. 
Result so far: 174685.50676982
If we subtract 1034 from 1340, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

In conclusion, the division gives 174685.50676982 with a balance of 3.06e-07.
