We divide 993978 by 17
The aim is to understand the frequency of 17 in 993978.

On to step 1:
17 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 17

Moving on to step 2:
When dividing 99 by 17, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 14 after subtracting 85 from 99.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 17

Let's proceed to step 3:
The number 17 fits into 143 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Deduct 136 from 143 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 17

On to step 4:
When dividing 79 by 17, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 584.0
The remainder is 11 after subtracting 68 from 79.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 17

Step 5:
When dividing 117 by 17, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 5846.0
Deduct 102 from 117 and we're left with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 17

Moving on to step 6:
If we divide 158 by 17, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 58469.0
If we take 153 away from 158, 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.

Advancing to step 7:
50 divided by 17 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 58469.2
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
17 goes into 160 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 58469.29
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 17 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 58469.294
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 58469.2941
If we subtract 17 from 20, we 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 11:
When dividing 30 by 17, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 58469.29411
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 58469.29411 and a remainder of 1.3e-05.
