39891396 ÷ 664 
We want to divide 39891396 by 664.

Moving on to step 1:
When dividing 3 by 664, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 664

Moving on to step 2:
The number 664 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 664

Let's proceed to step 3:
398 divided by 664 is 0 with a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Grab the next digit (9) from the dividend, add it to 398, then carry on: 3989 / 664

Going ahead to step 4:
The number 664 fits into 3989 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 3984 away from 3989, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 664

Step 5:
664 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 664

Going ahead to step 6:
664 goes into 513 0 times with a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 600.0
Subtract 0 from 513 to get 513.
Include the next digit (9) from the dividend after 513, then repeat: 5139 / 664

Step 7:
664 goes into 5139 7 times with a remainder of 491.
Write down 7 as next digit of the result. 
Result so far: 6007.0
Subtract 4648 from 5139 to get 491.
Fetch the next digit (6) from the dividend, attach it to 491 and continue: 4916 / 664

Step 8:
If we divide 4916 by 664, we get 7 and a remainder of 268.
Put 7 as the next digit of the answer. 
Result so far: 60077.0
Subtracting 4648 from 4916 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 9:
When dividing 2680 by 664, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 60077.4
The remainder is 24 after subtracting 2656 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
664 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 60077.4
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
2400 divided by 664 is 3 with a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 60077.403
Subtracting 1992 from 2400 leaves us 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.

Let's proceed to step 12:
4080 divided by 664 is 6 with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 60077.4036
Subtracting 3984 from 4080 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
The number 664 fits into 960 1 times, leaving a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 60077.40361
If we subtract 664 from 960, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 14:
When dividing 2960 by 664, we get 4 with a remainder of 304.
The next digit of our result is 4. 
Result so far: 60077.403614
If we take 2656 away from 2960, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
664 can be fit into 3040 4 times, resulting in a remainder of 384.
The number 4 becomes the next digit in our result. 
Result so far: 60077.4036144
If we take 2656 away from 3040, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 60077.4036144, and the remainder is 3.84e-06.
