Let's divide 31321645 by 270
The aim is to understand the frequency of 270 in 31321645.

Advancing to step 1:
The number 270 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 270

Step 2:
If we divide 31 by 270, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 270

Step 3:
270 can be fit into 313 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 270 from 313, we get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 270

Going ahead to step 4:
If we divide 432 by 270, we get 1 and a remainder of 162.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 270 from 432, we get 162.
Include the next digit (1) from the dividend after 162, then repeat: 1621 / 270

Let's proceed to step 5:
When dividing 1621 by 270, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtract 1620 from 1621 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 270

Going ahead to step 6:
16 divided by 270 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 1160.0
Subtract 0 from 16 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 270

Advancing to step 7:
The number 270 fits into 164 0 times, leaving a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 11600.0
If we subtract 0 from 164, we get 164.
Grab the next digit (5) from the dividend, add it to 164, then carry on: 1645 / 270

Going ahead to step 8:
If we divide 1645 by 270, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 116006.0
Subtract 1620 from 1645 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
The number 270 fits into 250 0 times, leaving a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 116006.0
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
If we divide 2500 by 270, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 116006.09
If we subtract 2430 from 2500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
270 can be fit into 700 2 times, resulting in a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 116006.092
Subtracting 540 from 700 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.

Going ahead to step 12:
270 can be fit into 1600 5 times, resulting in a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 116006.0925
Subtracting 1350 from 1600 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
270 goes into 2500 9 times with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 116006.09259
Subtracting 2430 from 2500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
700 divided by 270 is 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 116006.092592
If we subtract 540 from 700, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
1600 divided by 270 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 116006.0925925
Subtracting 1350 from 1600 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 16:
When dividing 2500 by 270, we get 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 116006.09259259
Subtracting 2430 from 2500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 116006.09259259 with a remainder of 7e-08.
