91023 divided by 16 
We're looking to find how many times 16 goes into 91023.

Step 1:
16 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 16

On to step 2:
If we divide 91 by 16, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 11 after subtracting 80 from 91.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 16

Going ahead to step 3:
The number 16 fits into 110 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 96 from 110, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 16

Moving on to step 4:
142 divided by 16 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 568.0
Subtract 128 from 142 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 16

Step 5:
If we divide 143 by 16, we get 8 and a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 5688.0
If we take 128 away from 143, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
When dividing 150 by 16, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 5688.9
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 16, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 5688.93
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.

Step 8:
If we divide 120 by 16, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 5688.937
Subtract 112 from 120 to get 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 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5688.9375
If we subtract 80 from 80, we get 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 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5688.9375
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.

On to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5688.9375
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.

The quotient of the division is 5688.9375, and the remainder is 0.0.
