We divide 16637927 by 406
Let's see how many times 406 fits into 16637927.

Step 1:
406 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 406

On to step 2:
406 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 406

Moving on to step 3:
The number 406 fits into 166 0 times, leaving a remainder of 166.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 166 and we're left with 166.
Bring next digit (3) of the dividend behind the 166 and repeat the process: 1663 / 406

Advancing to step 4:
The number 406 fits into 1663 4 times, leaving a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1624 from 1663 to get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 406

Step 5:
406 goes into 397 0 times with a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 397, we end up with 397.
Bring next digit (9) of the dividend behind the 397 and repeat the process: 3979 / 406

Let's proceed to step 6:
If we divide 3979 by 406, we get 9 and a remainder of 325.
The next digit of our result is 9. 
Result so far: 409.0
Subtract 3654 from 3979 to get 325.
Include the next digit (2) from the dividend after 325, then repeat: 3252 / 406

Going ahead to step 7:
When dividing 3252 by 406, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4098.0
The remainder is 4 after subtracting 3248 from 3252.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 406

Moving on to step 8:
406 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 40980.0
If we subtract 0 from 47, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
406 goes into 470 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 40980.1
If we take 406 away from 470, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
406 can be fit into 640 1 times, resulting in a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 40980.11
Subtract 406 from 640 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final result is 40980.11 with a remainder of 0.234.
