We look at the division of 16073399 by 423 
Our goal is to divide 16073399 by 423.

Going ahead to step 1:
423 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 423

Step 2:
423 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 423

Going ahead to step 3:
When dividing 160 by 423, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 160 and we're left with 160.
Bring next digit (7) of the dividend behind the 160 and repeat the process: 1607 / 423

Advancing to step 4:
If we divide 1607 by 423, we get 3 and a remainder of 338.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1269 from 1607 to get 338.
Grab the next digit (3) from the dividend, add it to 338, then carry on: 3383 / 423

Advancing to step 5:
If we divide 3383 by 423, we get 7 and a remainder of 422.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 2961 from 3383, we get 422.
Bring next digit (3) of the dividend behind the 422 and repeat the process: 4223 / 423

Let's proceed to step 6:
When dividing 4223 by 423, we get 9 with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 379.0
Subtracting 3807 from 4223 leaves us with 416.
Include the next digit (9) from the dividend after 416, then repeat: 4169 / 423

Advancing to step 7:
When dividing 4169 by 423, we get 9 with a remainder of 362.
Write down 9 as next digit of the result. 
Result so far: 3799.0
Subtract 3807 from 4169 to get 362.
Include the next digit (9) from the dividend after 362, then repeat: 3629 / 423

Moving on to step 8:
When dividing 3629 by 423, we get 8 with a remainder of 245.
The number 8 becomes the next digit in our result. 
Result so far: 37998.0
If we take 3384 away from 3629, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 9:
423 can be fit into 2450 5 times, resulting in a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 37998.5
The remainder is 335 after subtracting 2115 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 10:
423 can be fit into 3350 7 times, resulting in a remainder of 389.
Use 7 as the next digit of our solution. 
Result so far: 37998.57
The remainder is 389 after subtracting 2961 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 11:
3890 divided by 423 is 9 with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 37998.579
If we subtract 3807 from 3890, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
423 goes into 830 1 times with a remainder of 407.
Use 1 as the next digit of our solution. 
Result so far: 37998.5791
Subtract 423 from 830 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 13:
The number 423 fits into 4070 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 37998.57919
Deduct 3807 from 4070 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 14:
If we divide 2630 by 423, we get 6 and a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 37998.579196
If we subtract 2538 from 2630, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 15:
423 can be fit into 920 2 times, resulting in a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 37998.5791962
Subtract 846 from 920 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 16:
The number 423 fits into 740 1 times, leaving a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 37998.57919621
If we subtract 423 from 740, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final outcome is 37998.57919621, with a leftover of 3.17e-07.
