78168680 ÷ 270 
The aim is to understand the frequency of 270 in 78168680.

Advancing to step 1:
7 divided by 270 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 270

Going ahead to step 2:
270 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 270

On to step 3:
If we divide 781 by 270, we get 2 and a remainder of 241.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 540 away from 781, we end up with 241.
Fetch the next digit (6) from the dividend, attach it to 241 and continue: 2416 / 270

Step 4:
270 goes into 2416 8 times with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 2160 from 2416 leaves us with 256.
Take the next digit (8) from the dividend and append it to 256, then repeat: 2568 / 270

Advancing to step 5:
270 can be fit into 2568 9 times, resulting in a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtracting 2430 from 2568 leaves us with 138.
Append the next digit (6) from the dividend to 138 and continue with: 1386 / 270

Moving on to step 6:
270 can be fit into 1386 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 2895.0
Deduct 1350 from 1386 and we're left with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 270

Advancing to step 7:
270 can be fit into 368 1 times, resulting in a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 28951.0
If we take 270 away from 368, we end up with 98.
Take the next digit (0) from the dividend and append it to 98, then repeat: 980 / 270

On to step 8:
The number 270 fits into 980 3 times, leaving a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 289513.0
Deduct 810 from 980 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
When dividing 1700 by 270, we get 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 289513.6
If we subtract 1620 from 1700, 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.

Moving on to step 10:
If we divide 800 by 270, we get 2 and a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 289513.62
If we take 540 away from 800, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
The number 270 fits into 2600 9 times, leaving a remainder of 170.
The next digit of our result is 9. 
Result so far: 289513.629
The remainder is 170 after subtracting 2430 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
If we divide 1700 by 270, we get 6 and a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 289513.6296
The remainder is 80 after subtracting 1620 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
If we divide 800 by 270, we get 2 and a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 289513.62962
Deduct 540 from 800 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
If we divide 2600 by 270, we get 9 and a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 289513.629629
Subtracting 2430 from 2600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 15:
270 goes into 1700 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 289513.6296296
Subtract 1620 from 1700 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.

Let's proceed to step 16:
The number 270 fits into 800 2 times, leaving a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 289513.62962962
If we take 540 away from 800, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 289513.62962962 with a remaining 2.6e-07.
