We look at the division of 681390 by 17 
The aim is to understand the frequency of 17 in 681390.

Moving on to step 1:
17 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 17

On to step 2:
68 divided by 17 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 68 from 68.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 17

Let's proceed to step 3:
17 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 17

Advancing to step 4:
The number 17 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Subtract 0 from 13 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 17

Advancing to step 5:
17 goes into 139 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 4008.0
The remainder is 3 after subtracting 136 from 139.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 17

On to step 6:
When dividing 30 by 17, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 40081.0
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
17 can be fit into 130 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 40081.7
If we take 119 away from 130, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
The number 17 fits into 110 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 40081.76
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 9:
80 divided by 17 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 40081.764
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.

Step 10:
17 goes into 120 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 40081.7647
Deduct 119 from 120 and we're left 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.

Moving on to step 11:
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: 40081.7647
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.

Advancing to step 12:
100 divided by 17 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 40081.764705
Deduct 85 from 100 and we're left 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.

Going ahead to step 13:
150 divided by 17 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 40081.7647058
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.

Going ahead to step 14:
If we divide 140 by 17, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 40081.76470588
Subtract 136 from 140 to 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 quotient of the division is 40081.76470588, and the remainder is 4e-09.
