18396938 divided by 668 
We're looking to find how many times 668 goes into 18396938.

Let's proceed to step 1:
The number 668 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 668

Going ahead to step 2:
18 divided by 668 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 668

Step 3:
668 can be fit into 183 0 times, resulting in a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Bring next digit (9) of the dividend behind the 183 and repeat the process: 1839 / 668

Step 4:
668 goes into 1839 2 times with a remainder of 503.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1336 from 1839 and we're left with 503.
Include the next digit (6) from the dividend after 503, then repeat: 5036 / 668

Moving on to step 5:
If we divide 5036 by 668, we get 7 and a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 4676 from 5036 and we're left with 360.
Append the next digit (9) from the dividend to 360 and continue with: 3609 / 668

Step 6:
The number 668 fits into 3609 5 times, leaving a remainder of 269.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.0
Subtract 3340 from 3609 to get 269.
Grab the next digit (3) from the dividend, add it to 269, then carry on: 2693 / 668

Going ahead to step 7:
668 goes into 2693 4 times with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 2754.0
The remainder is 21 after subtracting 2672 from 2693.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 668

Let's proceed to step 8:
218 divided by 668 is 0 with a remainder of 218.
The next digit of our result is 0. 
Result so far: 27540.0
If we subtract 0 from 218, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 9:
If we divide 2180 by 668, we get 3 and a remainder of 176.
Write down 3 as next digit of the result. 
Result so far: 27540.3
Subtract 2004 from 2180 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 10:
The number 668 fits into 1760 2 times, leaving a remainder of 424.
Use 2 as the next digit of our solution. 
Result so far: 27540.32
If we take 1336 away from 1760, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
When dividing 4240 by 668, we get 6 with a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 27540.326
If we subtract 4008 from 4240, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 12:
When dividing 2320 by 668, we get 3 with a remainder of 316.
The next digit of our result is 3. 
Result so far: 27540.3263
Subtract 2004 from 2320 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
When dividing 3160 by 668, we get 4 with a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 27540.32634
If we subtract 2672 from 3160, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 14:
The number 668 fits into 4880 7 times, leaving a remainder of 204.
The next digit of our result is 7. 
Result so far: 27540.326347
Subtract 4676 from 4880 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 15:
The number 668 fits into 2040 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 27540.3263473
Subtract 2004 from 2040 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 16:
668 can be fit into 360 0 times, resulting in a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 27540.3263473
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 27540.3263473, with a leftover of 3.6e-07.
