80511198 ÷ 310 
The aim is to understand the frequency of 310 in 80511198.

Going ahead to step 1:
310 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 310

On to step 2:
310 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 310

On to step 3:
When dividing 805 by 310, we get 2 with a remainder of 185.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 620 from 805, we get 185.
Fetch the next digit (1) from the dividend, attach it to 185 and continue: 1851 / 310

Step 4:
310 goes into 1851 5 times with a remainder of 301.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1550 from 1851 and we're left with 301.
Grab the next digit (1) from the dividend, add it to 301, then carry on: 3011 / 310

Let's proceed to step 5:
310 goes into 3011 9 times with a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
Subtracting 2790 from 3011 leaves us with 221.
Append the next digit (1) from the dividend to 221 and continue with: 2211 / 310

Moving on to step 6:
310 goes into 2211 7 times with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 2597.0
Subtracting 2170 from 2211 leaves us with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 310

Moving on to step 7:
If we divide 419 by 310, we get 1 and a remainder of 109.
The next digit of our result is 1. 
Result so far: 25971.0
Subtracting 310 from 419 leaves us with 109.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 310

Let's proceed to step 8:
If we divide 1098 by 310, we get 3 and a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 259713.0
Subtracting 930 from 1098 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
If we divide 1680 by 310, we get 5 and a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 259713.5
The remainder is 130 after subtracting 1550 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
310 can be fit into 1300 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 259713.54
Subtracting 1240 from 1300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
310 goes into 600 1 times with a remainder of 290.
The next digit of our result is 1. 
Result so far: 259713.541
Deduct 310 from 600 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 12:
310 can be fit into 2900 9 times, resulting in a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 259713.5419
Subtracting 2790 from 2900 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
When dividing 1100 by 310, we get 3 with a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 259713.54193
Subtract 930 from 1100 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
The number 310 fits into 1700 5 times, leaving a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 259713.541935
Subtracting 1550 from 1700 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
If we divide 1500 by 310, we get 4 and a remainder of 260.
The next digit of our result is 4. 
Result so far: 259713.5419354
If we take 1240 away from 1500, 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.

On to step 16:
If we divide 2600 by 310, we get 8 and a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 259713.54193548
If we take 2480 away from 2600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 259713.54193548 with a remaining 1.2e-07.
