We look at the division of 76980998 by 235 
The aim is to understand the frequency of 235 in 76980998.

On to step 1:
The number 235 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 235

On to step 2:
235 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 235

Moving on to step 3:
The number 235 fits into 769 3 times, leaving a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 705 from 769 leaves us with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 235

Let's proceed to step 4:
If we divide 648 by 235, we get 2 and a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 470 from 648 to get 178.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 235

Moving on to step 5:
1780 divided by 235 is 7 with a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 327.0
Subtract 1645 from 1780 to get 135.
Bring next digit (9) of the dividend behind the 135 and repeat the process: 1359 / 235

On to step 6:
235 goes into 1359 5 times with a remainder of 184.
The next digit of our result is 5. 
Result so far: 3275.0
The remainder is 184 after subtracting 1175 from 1359.
Append the next digit (9) from the dividend to 184 and continue with: 1849 / 235

Let's proceed to step 7:
235 goes into 1849 7 times with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 32757.0
Subtract 1645 from 1849 to get 204.
Append the next digit (8) from the dividend to 204 and continue with: 2048 / 235

Let's proceed to step 8:
If we divide 2048 by 235, we get 8 and a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 327578.0
Subtracting 1880 from 2048 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.

Step 9:
If we divide 1680 by 235, we get 7 and a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 327578.7
If we take 1645 away from 1680, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
235 can be fit into 350 1 times, resulting in a remainder of 115.
The next digit of our result is 1. 
Result so far: 327578.71
If we subtract 235 from 350, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 11:
The number 235 fits into 1150 4 times, leaving a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 327578.714
Subtract 940 from 1150 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
When dividing 2100 by 235, we get 8 with a remainder of 220.
The next digit of our result is 8. 
Result so far: 327578.7148
Subtracting 1880 from 2100 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
If we divide 2200 by 235, we get 9 and a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 327578.71489
The remainder is 85 after subtracting 2115 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
235 can be fit into 850 3 times, resulting in a remainder of 145.
The next digit of our result is 3. 
Result so far: 327578.714893
Deduct 705 from 850 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 15:
1450 divided by 235 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 327578.7148936
Deduct 1410 from 1450 and we're left 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 16:
235 can be fit into 400 1 times, resulting in a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 327578.71489361
If we subtract 235 from 400, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 327578.71489361, with a leftover of 1.65e-07.
