We look at the division of 30648487 by 168 
The aim is to understand the frequency of 168 in 30648487.

Let's proceed to step 1:
168 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 168

Advancing to step 2:
30 divided by 168 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 168

Moving on to step 3:
168 goes into 306 1 times with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 138 after subtracting 168 from 306.
Grab the next digit (4) from the dividend, add it to 138, then carry on: 1384 / 168

Moving on to step 4:
If we divide 1384 by 168, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 40 after subtracting 1344 from 1384.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 168

Let's proceed to step 5:
If we divide 408 by 168, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 182.0
If we take 336 away from 408, we end up with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 168

Going ahead to step 6:
724 divided by 168 is 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 1824.0
Subtracting 672 from 724 leaves us with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 168

Let's proceed to step 7:
168 goes into 528 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 18243.0
Deduct 504 from 528 and we're left with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 168

On to step 8:
The number 168 fits into 247 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 182431.0
If we subtract 168 from 247, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
168 can be fit into 790 4 times, resulting in a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 182431.4
If we take 672 away from 790, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
168 goes into 1180 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 182431.47
The remainder is 4 after subtracting 1176 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
168 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 182431.47
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 168 fits into 400 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 182431.4702
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
640 divided by 168 is 3 with a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 182431.47023
Subtracting 504 from 640 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
The number 168 fits into 1360 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 182431.470238
If we subtract 1344 from 1360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
If we divide 160 by 168, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 182431.470238
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
If we divide 1600 by 168, we get 9 and a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 182431.47023809
If we take 1512 away from 1600, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 182431.47023809, and the remainder is 8.8e-08.
