90438293 divided by 664 
We want to divide 90438293 by 664.

Going ahead to step 1:
664 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 664

Moving on to step 2:
When dividing 90 by 664, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 664

Going ahead to step 3:
When dividing 904 by 664, we get 1 with a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 664 away from 904, we end up with 240.
Grab the next digit (3) from the dividend, add it to 240, then carry on: 2403 / 664

Let's proceed to step 4:
664 goes into 2403 3 times with a remainder of 411.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1992 from 2403 leaves us with 411.
Append the next digit (8) from the dividend to 411 and continue with: 4118 / 664

Moving on to step 5:
4118 divided by 664 is 6 with a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we take 3984 away from 4118, we end up with 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 664

Let's proceed to step 6:
The number 664 fits into 1342 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 1362.0
Subtracting 1328 from 1342 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 664

On to step 7:
If we divide 149 by 664, we get 0 and a remainder of 149.
The next digit of our result is 0. 
Result so far: 13620.0
If we subtract 0 from 149, we get 149.
Take the next digit (3) from the dividend and append it to 149, then repeat: 1493 / 664

Let's proceed to step 8:
1493 divided by 664 is 2 with a remainder of 165.
Record the quotient 2 as the next digit in the result. 
Result so far: 136202.0
Subtracting 1328 from 1493 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
The number 664 fits into 1650 2 times, leaving a remainder of 322.
Use 2 as the next digit of our solution. 
Result so far: 136202.2
If we subtract 1328 from 1650, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 10:
If we divide 3220 by 664, we get 4 and a remainder of 564.
The number 4 becomes the next digit in our result. 
Result so far: 136202.24
Subtract 2656 from 3220 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 11:
5640 divided by 664 is 8 with a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 136202.248
If we subtract 5312 from 5640, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
When dividing 3280 by 664, we get 4 with a remainder of 624.
Write down 4 as next digit of the result. 
Result so far: 136202.2484
If we subtract 2656 from 3280, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 13:
664 can be fit into 6240 9 times, resulting in a remainder of 264.
Put 9 as the next digit of the answer. 
Result so far: 136202.24849
If we take 5976 away from 6240, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 14:
2640 divided by 664 is 3 with a remainder of 648.
Record the quotient 3 as the next digit in the result. 
Result so far: 136202.248493
Deduct 1992 from 2640 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 15:
6480 divided by 664 is 9 with a remainder of 504.
Put 9 as the next digit of the answer. 
Result so far: 136202.2484939
If we take 5976 away from 6480, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 16:
If we divide 5040 by 664, we get 7 and a remainder of 392.
Record the quotient 7 as the next digit in the result. 
Result so far: 136202.24849397
If we take 4648 away from 5040, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

In conclusion, the division gives 136202.24849397 with a balance of 3.92e-07.
