83942199 ÷ 664 
Let's see how many times 664 fits into 83942199.

Step 1:
If we divide 8 by 664, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 664

On to step 2:
The number 664 fits into 83 0 times, leaving a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 664

Moving on to step 3:
When dividing 839 by 664, we get 1 with a remainder of 175.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 664 away from 839, we end up with 175.
Fetch the next digit (4) from the dividend, attach it to 175 and continue: 1754 / 664

Moving on to step 4:
664 can be fit into 1754 2 times, resulting in a remainder of 426.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1328 from 1754, we get 426.
Fetch the next digit (2) from the dividend, attach it to 426 and continue: 4262 / 664

Step 5:
The number 664 fits into 4262 6 times, leaving a remainder of 278.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we subtract 3984 from 4262, we get 278.
Include the next digit (1) from the dividend after 278, then repeat: 2781 / 664

Let's proceed to step 6:
664 can be fit into 2781 4 times, resulting in a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 1264.0
Subtracting 2656 from 2781 leaves us with 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 664

Advancing to step 7:
664 can be fit into 1259 1 times, resulting in a remainder of 595.
The next digit of our result is 1. 
Result so far: 12641.0
The remainder is 595 after subtracting 664 from 1259.
Include the next digit (9) from the dividend after 595, then repeat: 5959 / 664

Advancing to step 8:
If we divide 5959 by 664, we get 8 and a remainder of 647.
The next digit of our result is 8. 
Result so far: 126418.0
Deduct 5312 from 5959 and we're left with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

On to step 9:
If we divide 6470 by 664, we get 9 and a remainder of 494.
Write down 9 as next digit of the result. 
Result so far: 126418.9
If we subtract 5976 from 6470, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 10:
The number 664 fits into 4940 7 times, leaving a remainder of 292.
The next digit of our result is 7. 
Result so far: 126418.97
If we subtract 4648 from 4940, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 11:
The number 664 fits into 2920 4 times, leaving a remainder of 264.
The next digit of our result is 4. 
Result so far: 126418.974
If we take 2656 away from 2920, 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.

Advancing to step 12:
When dividing 2640 by 664, we get 3 with a remainder of 648.
Put 3 as the next digit of the answer. 
Result so far: 126418.9743
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.

Step 13:
The number 664 fits into 6480 9 times, leaving a remainder of 504.
The number 9 becomes the next digit in our result. 
Result so far: 126418.97439
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.

Advancing to step 14:
If we divide 5040 by 664, we get 7 and a remainder of 392.
The next digit of our result is 7. 
Result so far: 126418.974397
Subtract 4648 from 5040 to 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 15:
664 can be fit into 3920 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 126418.9743975
Deduct 3320 from 3920 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
664 can be fit into 6000 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 126418.97439759
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.

The final result is 126418.97439759 with a remainder of 2.4e-08.
