873915 ÷ 16 
The aim is to understand the frequency of 16 in 873915.

Going ahead to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 16

On to step 2:
When dividing 87 by 16, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 80 from 87 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 16

On to step 3:
73 divided by 16 is 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we subtract 64 from 73, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 16

Advancing to step 4:
99 divided by 16 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 546.0
Deduct 96 from 99 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 16

Advancing to step 5:
When dividing 31 by 16, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 5461.0
If we subtract 16 from 31, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 16

Let's proceed to step 6:
If we divide 155 by 16, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 54619.0
If we subtract 144 from 155, we 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.

On to step 7:
The number 16 fits into 110 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 54619.6
The remainder is 14 after subtracting 96 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 54619.68
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.

Moving on to step 9:
16 goes into 120 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 54619.687
The remainder is 8 after subtracting 112 from 120.
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.
Write down 5 as next digit of the result. 
Result so far: 54619.6875
Subtracting 80 from 80 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.
The number 0 becomes the next digit in our result. 
Result so far: 54619.6875
Deduct 0 from 0 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.

On to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54619.6875
If we subtract 0 from 0, 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.

The quotient of the division is 54619.6875, and the remainder is 0.0.
