We divide 90087036 by 310
The aim is to understand the frequency of 310 in 90087036.

Moving on to step 1:
9 divided by 310 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 310

Moving on to step 2:
310 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 310

Going ahead to step 3:
900 divided by 310 is 2 with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 620 away from 900, we end up with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 310

On to step 4:
If we divide 2808 by 310, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 2790 away from 2808, we end up with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 310

Let's proceed to step 5:
If we divide 187 by 310, we get 0 and a remainder of 187.
Put 0 as the next digit of the answer. 
Result so far: 290.0
If we subtract 0 from 187, we get 187.
Grab the next digit (0) from the dividend, add it to 187, then carry on: 1870 / 310

Going ahead to step 6:
The number 310 fits into 1870 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2906.0
If we subtract 1860 from 1870, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 310

Step 7:
310 goes into 103 0 times with a remainder of 103.
The next digit of our result is 0. 
Result so far: 29060.0
Subtracting 0 from 103 leaves us with 103.
Include the next digit (6) from the dividend after 103, then repeat: 1036 / 310

Step 8:
If we divide 1036 by 310, we get 3 and a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 290603.0
Deduct 930 from 1036 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
When dividing 1060 by 310, we get 3 with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 290603.3
Subtracting 930 from 1060 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
The number 310 fits into 1300 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 290603.34
The remainder is 60 after subtracting 1240 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
600 divided by 310 is 1 with a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 290603.341
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.

Moving 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: 290603.3419
The remainder is 110 after subtracting 2790 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
1100 divided by 310 is 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 290603.34193
If we take 930 away from 1100, we end up 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.

Step 14:
If we divide 1700 by 310, we get 5 and a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 290603.341935
If we subtract 1550 from 1700, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
1500 divided by 310 is 4 with a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 290603.3419354
The remainder is 260 after subtracting 1240 from 1500.
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:
When dividing 2600 by 310, we get 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 290603.34193548
Subtracting 2480 from 2600 leaves us 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.

In conclusion, the division gives 290603.34193548 with a balance of 1.2e-07.
