Let's divide 15922434 by 408
We want to figure out the number of times 15922434 can be divided by 408.

Step 1:
The number 408 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 408

Step 2:
408 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 408

On to step 3:
The number 408 fits into 159 0 times, leaving a remainder of 159.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Append the next digit (2) from the dividend to 159 and continue with: 1592 / 408

Going ahead to step 4:
The number 408 fits into 1592 3 times, leaving a remainder of 368.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1224 from 1592 leaves us with 368.
Include the next digit (2) from the dividend after 368, then repeat: 3682 / 408

Moving on to step 5:
When dividing 3682 by 408, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 3672 from 3682 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 408

Moving on to step 6:
104 divided by 408 is 0 with a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 390.0
Subtracting 0 from 104 leaves us with 104.
Take the next digit (3) from the dividend and append it to 104, then repeat: 1043 / 408

Advancing to step 7:
1043 divided by 408 is 2 with a remainder of 227.
Use 2 as the next digit of our solution. 
Result so far: 3902.0
Subtracting 816 from 1043 leaves us with 227.
Fetch the next digit (4) from the dividend, attach it to 227 and continue: 2274 / 408

Going ahead to step 8:
The number 408 fits into 2274 5 times, leaving a remainder of 234.
Use 5 as the next digit of our solution. 
Result so far: 39025.0
Subtract 2040 from 2274 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.

Let's proceed to step 9:
The number 408 fits into 2340 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 39025.5
Subtracting 2040 from 2340 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
3000 divided by 408 is 7 with a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 39025.57
Subtracting 2856 from 3000 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
The number 408 fits into 1440 3 times, leaving a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 39025.573
Deduct 1224 from 1440 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
408 goes into 2160 5 times with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 39025.5735
Subtract 2040 from 2160 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
408 goes into 1200 2 times with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 39025.57352
If we subtract 816 from 1200, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
When dividing 3840 by 408, we get 9 with a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 39025.573529
Subtracting 3672 from 3840 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 15:
If we divide 1680 by 408, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 39025.5735294
Subtracting 1632 from 1680 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
480 divided by 408 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 39025.57352941
Subtracting 408 from 480 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 39025.57352941 with a remainder of 7.2e-08.
