Let's divide 90816413 by 664
We want to figure out the number of times 90816413 can be divided by 664.

Let's proceed to step 1:
If we divide 9 by 664, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 664

Moving on to step 2:
90 divided by 664 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 664

Going ahead to step 3:
908 divided by 664 is 1 with a remainder of 244.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 664 from 908, we get 244.
Append the next digit (1) from the dividend to 244 and continue with: 2441 / 664

On to step 4:
664 goes into 2441 3 times with a remainder of 449.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1992 from 2441 to get 449.
Append the next digit (6) from the dividend to 449 and continue with: 4496 / 664

On to step 5:
The number 664 fits into 4496 6 times, leaving a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 3984 from 4496 to get 512.
Append the next digit (4) from the dividend to 512 and continue with: 5124 / 664

Going ahead to step 6:
5124 divided by 664 is 7 with a remainder of 476.
Use 7 as the next digit of our solution. 
Result so far: 1367.0
The remainder is 476 after subtracting 4648 from 5124.
Bring next digit (1) of the dividend behind the 476 and repeat the process: 4761 / 664

Step 7:
If we divide 4761 by 664, we get 7 and a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 13677.0
If we subtract 4648 from 4761, we get 113.
Grab the next digit (3) from the dividend, add it to 113, then carry on: 1133 / 664

Moving on to step 8:
When dividing 1133 by 664, we get 1 with a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 136771.0
Subtract 664 from 1133 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Advancing to step 9:
The number 664 fits into 4690 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 136771.7
Subtracting 4648 from 4690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
664 goes into 420 0 times with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 136771.7
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
If we divide 4200 by 664, we get 6 and a remainder of 216.
The next digit of our result is 6. 
Result so far: 136771.706
If we subtract 3984 from 4200, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
When dividing 2160 by 664, we get 3 with a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 136771.7063
The remainder is 168 after subtracting 1992 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
The number 664 fits into 1680 2 times, leaving a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 136771.70632
If we subtract 1328 from 1680, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
If we divide 3520 by 664, we get 5 and a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 136771.706325
Subtract 3320 from 3520 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
664 can be fit into 2000 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 136771.7063253
If we subtract 1992 from 2000, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
When dividing 80 by 664, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 136771.7063253
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 136771.7063253 with a remaining 8e-08.
