31664 divided by 49 
We're looking to find how many times 49 goes into 31664.

On to step 1:
If we divide 3 by 49, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 49

Let's proceed to step 2:
When dividing 31 by 49, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 49

On to step 3:
316 divided by 49 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 22 after subtracting 294 from 316.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 49

Step 4:
When dividing 226 by 49, we get 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 196 from 226 to get 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 49

On to step 5:
The number 49 fits into 304 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 646.0
Subtracting 294 from 304 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
49 can be fit into 100 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 646.2
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
49 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 646.2
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
49 can be fit into 200 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 646.204
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
49 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 646.204
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
49 can be fit into 400 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 646.20408
Subtract 392 from 400 to 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.

Let's proceed to step 11:
If we divide 80 by 49, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 646.204081
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
49 can be fit into 310 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 646.2040816
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 49, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 646.20408163
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 646.20408163 with a remainder of 1.3e-08.
