16426503 ÷ 408 
We're looking to find how many times 408 goes into 16426503.

Let's proceed to step 1:
1 divided by 408 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 408

Going ahead to step 2:
408 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 408

Going ahead to step 3:
408 goes into 164 0 times with a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 408

Step 4:
1642 divided by 408 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1632 from 1642 to get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 408

Going ahead to step 5:
408 goes into 106 0 times with a remainder of 106.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 106 after subtracting 0 from 106.
Bring next digit (5) of the dividend behind the 106 and repeat the process: 1065 / 408

Step 6:
If we divide 1065 by 408, we get 2 and a remainder of 249.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtracting 816 from 1065 leaves us with 249.
Append the next digit (0) from the dividend to 249 and continue with: 2490 / 408

Advancing to step 7:
408 goes into 2490 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 4026.0
The remainder is 42 after subtracting 2448 from 2490.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 408

Going ahead to step 8:
When dividing 423 by 408, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 40261.0
The remainder is 15 after subtracting 408 from 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
408 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 40261.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
1500 divided by 408 is 3 with a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 40261.03
If we subtract 1224 from 1500, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
When dividing 2760 by 408, we get 6 with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 40261.036
Deduct 2448 from 2760 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 12:
408 goes into 3120 7 times with a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 40261.0367
Subtracting 2856 from 3120 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 13:
408 goes into 2640 6 times with a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 40261.03676
Deduct 2448 from 2640 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
The number 408 fits into 1920 4 times, leaving a remainder of 288.
The next digit of our result is 4. 
Result so far: 40261.036764
If we subtract 1632 from 1920, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
408 goes into 2880 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 40261.0367647
The remainder is 24 after subtracting 2856 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
408 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 40261.0367647
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 40261.0367647 with a remainder of 2.4e-07.
