85243450 divided by 664 
Our goal is to divide 85243450 by 664.

Step 1:
When dividing 8 by 664, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 664

Going ahead to step 2:
If we divide 85 by 664, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 664

Step 3:
The number 664 fits into 852 1 times, leaving a remainder of 188.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 664 from 852 and we're left with 188.
Take the next digit (4) from the dividend and append it to 188, then repeat: 1884 / 664

Step 4:
When dividing 1884 by 664, we get 2 with a remainder of 556.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1328 from 1884, we get 556.
Append the next digit (3) from the dividend to 556 and continue with: 5563 / 664

Advancing to step 5:
664 can be fit into 5563 8 times, resulting in a remainder of 251.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 5312 from 5563 to get 251.
Fetch the next digit (4) from the dividend, attach it to 251 and continue: 2514 / 664

Step 6:
664 can be fit into 2514 3 times, resulting in a remainder of 522.
The next digit of our result is 3. 
Result so far: 1283.0
Subtracting 1992 from 2514 leaves us with 522.
Bring next digit (5) of the dividend behind the 522 and repeat the process: 5225 / 664

Step 7:
664 goes into 5225 7 times with a remainder of 577.
Write down 7 as next digit of the result. 
Result so far: 12837.0
Subtract 4648 from 5225 to get 577.
Bring next digit (0) of the dividend behind the 577 and repeat the process: 5770 / 664

Step 8:
When dividing 5770 by 664, we get 8 with a remainder of 458.
Put 8 as the next digit of the answer. 
Result so far: 128378.0
The remainder is 458 after subtracting 5312 from 5770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 9:
664 can be fit into 4580 6 times, resulting in a remainder of 596.
Put 6 as the next digit of the answer. 
Result so far: 128378.6
Deduct 3984 from 4580 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 10:
When dividing 5960 by 664, we get 8 with a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 128378.68
Deduct 5312 from 5960 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.

Going ahead to step 11:
664 can be fit into 6480 9 times, resulting in a remainder of 504.
The next digit of our result is 9. 
Result so far: 128378.689
Subtracting 5976 from 6480 leaves us 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.

Going ahead to step 12:
5040 divided by 664 is 7 with a remainder of 392.
Put 7 as the next digit of the answer. 
Result so far: 128378.6897
If we subtract 4648 from 5040, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 13:
The number 664 fits into 3920 5 times, leaving a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 128378.68975
The remainder is 600 after subtracting 3320 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
When dividing 6000 by 664, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 128378.689759
The remainder is 24 after subtracting 5976 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
If we divide 240 by 664, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 128378.689759
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
If we divide 2400 by 664, we get 3 and a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 128378.68975903
If we take 1992 away from 2400, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 128378.68975903, with a leftover of 4.08e-07.
