We divide 136890 by 16
We want to figure out the number of times 136890 can be divided by 16.

Step 1:
If we divide 1 by 16, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 16

Step 2:
16 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 16

On to step 3:
The number 16 fits into 136 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 128 away from 136, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 16

On to step 4:
16 goes into 88 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 80 from 88 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 16

Going ahead to step 5:
If we divide 89 by 16, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 855.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 16

Moving on to step 6:
90 divided by 16 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8555.0
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
16 goes into 100 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8555.6
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 16, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8555.62
Subtracting 32 from 40 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 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8555.625
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.

Advancing to step 10:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8555.625
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.

On to 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: 8555.625
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.

The final outcome is 8555.625, with a leftover of 0.0.
