The aim is to understand the frequency of 310 in 72771555.

On to step 1:
7 divided by 310 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 310

Advancing to step 2:
If we divide 72 by 310, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 310

Moving on to step 3:
310 goes into 727 2 times with a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 620 away from 727, we end up with 107.
Include the next digit (7) from the dividend after 107, then repeat: 1077 / 310

Going ahead to step 4:
1077 divided by 310 is 3 with a remainder of 147.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 147 after subtracting 930 from 1077.
Fetch the next digit (1) from the dividend, attach it to 147 and continue: 1471 / 310

Advancing to step 5:
1471 divided by 310 is 4 with a remainder of 231.
Write down 4 as next digit of the result. 
Result so far: 234.0
If we subtract 1240 from 1471, we get 231.
Include the next digit (5) from the dividend after 231, then repeat: 2315 / 310

Advancing to step 6:
2315 divided by 310 is 7 with a remainder of 145.
The next digit of our result is 7. 
Result so far: 2347.0
Deduct 2170 from 2315 and we're left with 145.
Fetch the next digit (5) from the dividend, attach it to 145 and continue: 1455 / 310

Moving on to step 7:
310 goes into 1455 4 times with a remainder of 215.
The number 4 becomes the next digit in our result. 
Result so far: 23474.0
Subtract 1240 from 1455 to get 215.
Grab the next digit (5) from the dividend, add it to 215, then carry on: 2155 / 310

Moving on to step 8:
310 goes into 2155 6 times with a remainder of 295.
Put 6 as the next digit of the answer. 
Result so far: 234746.0
The remainder is 295 after subtracting 1860 from 2155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 9:
When dividing 2950 by 310, we get 9 with a remainder of 160.
The next digit of our result is 9. 
Result so far: 234746.9
Deduct 2790 from 2950 and we're left 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.

Moving on to step 10:
1600 divided by 310 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 234746.95
If we take 1550 away from 1600, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
When dividing 500 by 310, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 234746.951
If we take 310 away from 500, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 12:
When dividing 1900 by 310, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 234746.9516
If we take 1860 away from 1900, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 310 is 1 with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 234746.95161
Deduct 310 from 400 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
If we divide 900 by 310, we get 2 and a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 234746.951612
If we take 620 away from 900, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
The number 310 fits into 2800 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 234746.9516129
Deduct 2790 from 2800 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
The number 310 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 234746.9516129
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 234746.9516129 with a balance of 1e-07.
