We look at the division of 51358122 by 310 
The aim is to understand the frequency of 310 in 51358122.

Advancing to step 1:
310 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 310

Step 2:
If we divide 51 by 310, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 310

Going ahead to step 3:
When dividing 513 by 310, we get 1 with a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 310 from 513 leaves us with 203.
Grab the next digit (5) from the dividend, add it to 203, then carry on: 2035 / 310

Step 4:
If we divide 2035 by 310, we get 6 and a remainder of 175.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 1860 from 2035 to get 175.
Fetch the next digit (8) from the dividend, attach it to 175 and continue: 1758 / 310

Moving on to step 5:
1758 divided by 310 is 5 with a remainder of 208.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
If we take 1550 away from 1758, we end up with 208.
Append the next digit (1) from the dividend to 208 and continue with: 2081 / 310

Advancing to step 6:
2081 divided by 310 is 6 with a remainder of 221.
Write down 6 as next digit of the result. 
Result so far: 1656.0
The remainder is 221 after subtracting 1860 from 2081.
Take the next digit (2) from the dividend and append it to 221, then repeat: 2212 / 310

Step 7:
310 goes into 2212 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 16567.0
Subtract 2170 from 2212 to get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 310

Let's proceed to step 8:
The number 310 fits into 422 1 times, leaving a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 165671.0
If we take 310 away from 422, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 9:
310 can be fit into 1120 3 times, resulting in a remainder of 190.
The next digit of our result is 3. 
Result so far: 165671.3
If we take 930 away from 1120, 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.

On to step 10:
If we divide 1900 by 310, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 165671.36
Subtracting 1860 from 1900 leaves us 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.

On to step 11:
400 divided by 310 is 1 with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 165671.361
If we subtract 310 from 400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
When dividing 900 by 310, we get 2 with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 165671.3612
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.

Moving on to step 13:
If we divide 2800 by 310, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 165671.36129
Subtract 2790 from 2800 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
310 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 165671.36129
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
The number 310 fits into 1000 3 times, leaving a remainder of 70.
The next digit of our result is 3. 
Result so far: 165671.3612903
If we take 930 away from 1000, we end up 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.

Going ahead to step 16:
310 goes into 700 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 165671.36129032
If we subtract 620 from 700, 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.

The final outcome is 165671.36129032, with a leftover of 8e-08.
