16224545 ÷ 407 
We want to figure out the number of times 16224545 can be divided by 407.

Step 1:
When dividing 1 by 407, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 407

Going ahead to step 2:
The number 407 fits into 16 0 times, leaving 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.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 407

Going ahead to step 3:
407 goes into 162 0 times with a remainder of 162.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 162, we get 162.
Include the next digit (2) from the dividend after 162, then repeat: 1622 / 407

On to step 4:
When dividing 1622 by 407, we get 3 with a remainder of 401.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1221 from 1622 leaves us with 401.
Append the next digit (4) from the dividend to 401 and continue with: 4014 / 407

Moving on to step 5:
407 can be fit into 4014 9 times, resulting in a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 351 after subtracting 3663 from 4014.
Bring next digit (5) of the dividend behind the 351 and repeat the process: 3515 / 407

Moving on to step 6:
407 can be fit into 3515 8 times, resulting in a remainder of 259.
The next digit of our result is 8. 
Result so far: 398.0
Subtracting 3256 from 3515 leaves us with 259.
Append the next digit (4) from the dividend to 259 and continue with: 2594 / 407

Moving on to step 7:
The number 407 fits into 2594 6 times, leaving a remainder of 152.
The next digit of our result is 6. 
Result so far: 3986.0
The remainder is 152 after subtracting 2442 from 2594.
Take the next digit (5) from the dividend and append it to 152, then repeat: 1525 / 407

On to step 8:
The number 407 fits into 1525 3 times, leaving a remainder of 304.
Record the quotient 3 as the next digit in the result. 
Result so far: 39863.0
Subtracting 1221 from 1525 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
407 goes into 3040 7 times with a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 39863.7
If we subtract 2849 from 3040, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 10:
The number 407 fits into 1910 4 times, leaving a remainder of 282.
The number 4 becomes the next digit in our result. 
Result so far: 39863.74
If we subtract 1628 from 1910, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
If we divide 2820 by 407, we get 6 and a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 39863.746
Subtract 2442 from 2820 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 12:
The number 407 fits into 3780 9 times, leaving a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 39863.7469
If we subtract 3663 from 3780, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 13:
407 goes into 1170 2 times with a remainder of 356.
Put 2 as the next digit of the answer. 
Result so far: 39863.74692
Subtracting 814 from 1170 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 14:
407 goes into 3560 8 times with a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 39863.746928
The remainder is 304 after subtracting 3256 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 15:
The number 407 fits into 3040 7 times, leaving a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 39863.7469287
If we take 2849 away from 3040, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 16:
The number 407 fits into 1910 4 times, leaving a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 39863.74692874
If we subtract 1628 from 1910, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The quotient of the division is 39863.74692874, and the remainder is 2.82e-07.
