87916778 ÷ 168 
The aim is to understand the frequency of 168 in 87916778.

Step 1:
8 divided by 168 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 168

Advancing to step 2:
168 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 168

Advancing to step 3:
168 goes into 879 5 times with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 840 away from 879, we end up with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 168

Moving on to step 4:
The number 168 fits into 391 2 times, leaving a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 336 away from 391, we end up with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 168

Going ahead to step 5:
When dividing 556 by 168, we get 3 with a remainder of 52.
The next digit of our result is 3. 
Result so far: 523.0
If we take 504 away from 556, we end up with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 168

Moving on to step 6:
527 divided by 168 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 5233.0
The remainder is 23 after subtracting 504 from 527.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 168

Let's proceed to step 7:
168 can be fit into 237 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 52331.0
Subtract 168 from 237 to get 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 168

Step 8:
168 goes into 698 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 523314.0
Subtract 672 from 698 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
260 divided by 168 is 1 with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 523314.1
If we take 168 away from 260, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
920 divided by 168 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 523314.15
If we subtract 840 from 920, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
168 can be fit into 800 4 times, resulting in a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 523314.154
If we subtract 672 from 800, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
1280 divided by 168 is 7 with a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 523314.1547
Subtract 1176 from 1280 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
168 can be fit into 1040 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 523314.15476
If we subtract 1008 from 1040, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
The number 168 fits into 320 1 times, leaving a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 523314.154761
The remainder is 152 after subtracting 168 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 15:
If we divide 1520 by 168, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 523314.1547619
Deduct 1512 from 1520 and we're left 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.

Going ahead to step 16:
168 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 523314.1547619
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 523314.1547619 with a remaining 8e-08.
