We look at the division of 170143 by 16 
We want to divide 170143 by 16.

Going ahead to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 16

On to step 2:
The number 16 fits into 17 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 16 from 17 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 16

Let's proceed to step 3:
The number 16 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 16

Advancing to step 4:
When dividing 101 by 16, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 96 from 101, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 16

Let's proceed to step 5:
When dividing 54 by 16, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1063.0
Deduct 48 from 54 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 16

Let's proceed to step 6:
63 divided by 16 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 10633.0
The remainder is 15 after subtracting 48 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 16 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 10633.9
Deduct 144 from 150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 10633.93
Subtracting 48 from 60 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 16, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 10633.937
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10633.9375
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10633.9375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10633.9375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10633.9375 with a remainder of 0.0.
