80830797 divided by 17 
The aim is to understand the frequency of 17 in 80830797.

Advancing to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 17

On to step 2:
The number 17 fits into 80 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 12 after subtracting 68 from 80.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 17

Going ahead to step 3:
128 divided by 17 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 119 from 128 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 17

Advancing to step 4:
If we divide 93 by 17, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 475.0
Deduct 85 from 93 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 17

Let's proceed to step 5:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4754.0
Subtract 68 from 80 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 17

Advancing to step 6:
17 can be fit into 127 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 47547.0
If we subtract 119 from 127, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 17

Moving on to step 7:
When dividing 89 by 17, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 475475.0
The remainder is 4 after subtracting 85 from 89.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 17

Step 8:
When dividing 47 by 17, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 4754752.0
The remainder is 13 after subtracting 34 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 17 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 4754752.7
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
When dividing 110 by 17, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4754752.76
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.

Going ahead to step 11:
17 goes into 80 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4754752.764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 4754752.7647
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4754752.7647
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
17 goes into 100 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4754752.764705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
150 divided by 17 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 4754752.7647058
If we take 136 away from 150, we end up 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.

Step 16:
If we divide 140 by 17, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4754752.76470588
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 4754752.76470588, with a leftover of 4e-09.
