We divide 129643 by 16
Our goal is to divide 129643 by 16.

Going ahead to step 1:
If we divide 1 by 16, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 16

Let's proceed to step 2:
If we divide 12 by 16, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 16

Moving on to step 3:
16 goes into 129 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 128 from 129 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 16

Going ahead to step 4:
If we divide 16 by 16, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 16 away from 16, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 16

Step 5:
4 divided by 16 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 16

On to step 6:
16 can be fit into 43 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 8102.0
Subtract 32 from 43 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 16, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 8102.6
If we subtract 96 from 110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 16 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8102.68
Deduct 128 from 140 and we're left 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.

Going ahead to step 9:
16 goes into 120 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 8102.687
Subtracting 112 from 120 leaves us 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.

Advancing to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 8102.6875
Deduct 80 from 80 and we're left 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.

Step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8102.6875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8102.6875
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.

The final outcome is 8102.6875, with a leftover of 0.0.
