Let's divide 67930778 by 515
The aim is to understand the frequency of 515 in 67930778.

Going ahead to step 1:
The number 515 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 515

Moving on to step 2:
67 divided by 515 is 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 515

Moving on to step 3:
679 divided by 515 is 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 515 from 679, we get 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 515

Advancing to step 4:
515 goes into 1643 3 times with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1545 from 1643 and we're left with 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 515

Going ahead to step 5:
If we divide 980 by 515, we get 1 and a remainder of 465.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Deduct 515 from 980 and we're left with 465.
Take the next digit (7) from the dividend and append it to 465, then repeat: 4657 / 515

Let's proceed to step 6:
4657 divided by 515 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 1319.0
If we subtract 4635 from 4657, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 515

Advancing to step 7:
515 goes into 227 0 times with a remainder of 227.
The number 0 becomes the next digit in our result. 
Result so far: 13190.0
The remainder is 227 after subtracting 0 from 227.
Append the next digit (8) from the dividend to 227 and continue with: 2278 / 515

Going ahead to step 8:
When dividing 2278 by 515, we get 4 with a remainder of 218.
The number 4 becomes the next digit in our result. 
Result so far: 131904.0
If we subtract 2060 from 2278, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 9:
515 can be fit into 2180 4 times, resulting in a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 131904.4
Subtracting 2060 from 2180 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.

Advancing to step 10:
515 can be fit into 1200 2 times, resulting in a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 131904.42
Subtracting 1030 from 1200 leaves us 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.

Moving on to step 11:
When dividing 1700 by 515, we get 3 with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 131904.423
The remainder is 155 after subtracting 1545 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 12:
515 can be fit into 1550 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 131904.4233
If we take 1545 away from 1550, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 131904.4233 and a remainder of 5e-05.
