Let's divide 76604978 by 17
The aim is to understand the frequency of 17 in 76604978.

Moving on to step 1:
If we divide 7 by 17, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 17

Going ahead to step 2:
76 divided by 17 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 68 away from 76, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 17

Moving on to step 3:
When dividing 86 by 17, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 85 from 86 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 17

Moving on to step 4:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 450.0
If we subtract 0 from 10, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 17

On to step 5:
104 divided by 17 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 4506.0
The remainder is 2 after subtracting 102 from 104.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 17

Let's proceed to step 6:
If we divide 29 by 17, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 45061.0
Subtracting 17 from 29 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 17

Let's proceed to step 7:
17 goes into 127 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 450617.0
If we take 119 away from 127, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 17

Going ahead to step 8:
When dividing 88 by 17, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 4506175.0
Subtract 85 from 88 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 17 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 4506175.1
If we take 17 away from 30, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
If we divide 130 by 17, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4506175.17
Subtract 119 from 130 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
17 can be fit into 110 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4506175.176
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 17, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4506175.1764
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
When dividing 120 by 17, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 4506175.17647
Subtract 119 from 120 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4506175.17647
Subtract 0 from 10 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 15:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4506175.1764705
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 16:
If we divide 150 by 17, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 4506175.17647058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 4506175.17647058, and the remainder is 1.4e-08.
