Let's divide 16369917 by 407
We're looking to find how many times 407 goes into 16369917.

Step 1:
1 divided by 407 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 407

On to step 2:
407 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 407

Moving on to step 3:
If we divide 163 by 407, we get 0 and a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 163 to get 163.
Grab the next digit (6) from the dividend, add it to 163, then carry on: 1636 / 407

Moving on to step 4:
When dividing 1636 by 407, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1628 away from 1636, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 407

Moving on to step 5:
407 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 89, we get 89.
Include the next digit (9) from the dividend after 89, then repeat: 899 / 407

Advancing to step 6:
The number 407 fits into 899 2 times, leaving a remainder of 85.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
Subtract 814 from 899 to get 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 407

On to step 7:
407 can be fit into 851 2 times, resulting in a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 4022.0
Deduct 814 from 851 and we're left with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 407

Going ahead to step 8:
If we divide 377 by 407, we get 0 and a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 40220.0
If we take 0 away from 377, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 9:
407 goes into 3770 9 times with a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 40220.9
Subtracting 3663 from 3770 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 10:
407 goes into 1070 2 times with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 40220.92
Subtract 814 from 1070 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 11:
If we divide 2560 by 407, we get 6 and a remainder of 118.
The number 6 becomes the next digit in our result. 
Result so far: 40220.926
If we take 2442 away from 2560, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 12:
If we divide 1180 by 407, we get 2 and a remainder of 366.
The next digit of our result is 2. 
Result so far: 40220.9262
Deduct 814 from 1180 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 13:
The number 407 fits into 3660 8 times, leaving a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 40220.92628
Deduct 3256 from 3660 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 14:
407 goes into 4040 9 times with a remainder of 377.
Write down 9 as next digit of the result. 
Result so far: 40220.926289
Deduct 3663 from 4040 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 15:
3770 divided by 407 is 9 with a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 40220.9262899
Subtract 3663 from 3770 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The quotient of the division is 40220.9262899, and the remainder is 1.07e-06.
