We're dividing 90313931 by 488 
We want to divide 90313931 by 488.

Going ahead to step 1:
488 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 488

Going ahead to step 2:
488 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 488

Let's proceed to step 3:
488 goes into 903 1 times with a remainder of 415.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 488 away from 903, we end up with 415.
Grab the next digit (1) from the dividend, add it to 415, then carry on: 4151 / 488

On to step 4:
If we divide 4151 by 488, we get 8 and a remainder of 247.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 3904 from 4151 and we're left with 247.
Take the next digit (3) from the dividend and append it to 247, then repeat: 2473 / 488

Let's proceed to step 5:
2473 divided by 488 is 5 with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Deduct 2440 from 2473 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 488

Step 6:
488 goes into 339 0 times with a remainder of 339.
Write down 0 as next digit of the result. 
Result so far: 1850.0
Subtracting 0 from 339 leaves us with 339.
Bring next digit (3) of the dividend behind the 339 and repeat the process: 3393 / 488

Going ahead to step 7:
The number 488 fits into 3393 6 times, leaving a remainder of 465.
Put 6 as the next digit of the answer. 
Result so far: 18506.0
If we subtract 2928 from 3393, we get 465.
Fetch the next digit (1) from the dividend, attach it to 465 and continue: 4651 / 488

On to step 8:
The number 488 fits into 4651 9 times, leaving a remainder of 259.
Record the quotient 9 as the next digit in the result. 
Result so far: 185069.0
If we subtract 4392 from 4651, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
2590 divided by 488 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 185069.5
Subtract 2440 from 2590 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
When dividing 1500 by 488, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 185069.53
If we take 1464 away from 1500, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 488, we get 0 and a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 185069.53
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
3600 divided by 488 is 7 with a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 185069.5307
Subtract 3416 from 3600 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
488 can be fit into 1840 3 times, resulting in a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 185069.53073
If we take 1464 away from 1840, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 14:
The number 488 fits into 3760 7 times, leaving a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 185069.530737
Deduct 3416 from 3760 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
488 goes into 3440 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 185069.5307377
Deduct 3416 from 3440 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 185069.5307377 with a balance of 2.4e-07.
