16900075 ÷ 402 
Our goal is to divide 16900075 by 402.

Step 1:
1 divided by 402 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 402

Step 2:
16 divided by 402 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 402

Moving on to step 3:
If we divide 169 by 402, we get 0 and a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 169 to get 169.
Append the next digit (0) from the dividend to 169 and continue with: 1690 / 402

Moving on to step 4:
When dividing 1690 by 402, we get 4 with a remainder of 82.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1608 from 1690 and we're left with 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 402

Moving on to step 5:
When dividing 820 by 402, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 804 from 820 and we're left with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 402

Moving on to step 6:
402 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Deduct 0 from 160 and we're left with 160.
Take the next digit (7) from the dividend and append it to 160, then repeat: 1607 / 402

Going ahead to step 7:
If we divide 1607 by 402, we get 3 and a remainder of 401.
Record the quotient 3 as the next digit in the result. 
Result so far: 4203.0
Subtract 1206 from 1607 to get 401.
Take the next digit (5) from the dividend and append it to 401, then repeat: 4015 / 402

Step 8:
When dividing 4015 by 402, we get 9 with a remainder of 397.
The next digit of our result is 9. 
Result so far: 42039.0
The remainder is 397 after subtracting 3618 from 4015.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 9:
The number 402 fits into 3970 9 times, leaving a remainder of 352.
The next digit of our result is 9. 
Result so far: 42039.9
If we subtract 3618 from 3970, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 10:
When dividing 3520 by 402, we get 8 with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 42039.98
If we subtract 3216 from 3520, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 11:
When dividing 3040 by 402, we get 7 with a remainder of 226.
Write down 7 as next digit of the result. 
Result so far: 42039.987
Subtract 2814 from 3040 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 12:
402 goes into 2260 5 times with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 42039.9875
The remainder is 250 after subtracting 2010 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 13:
If we divide 2500 by 402, we get 6 and a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 42039.98756
The remainder is 88 after subtracting 2412 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 14:
When dividing 880 by 402, we get 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 42039.987562
If we subtract 804 from 880, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
402 can be fit into 760 1 times, resulting in a remainder of 358.
Record the quotient 1 as the next digit in the result. 
Result so far: 42039.9875621
Subtracting 402 from 760 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 16:
402 goes into 3580 8 times with a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 42039.98756218
If we take 3216 away from 3580, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The quotient of the division is 42039.98756218, and the remainder is 3.64e-07.
