We're dividing 225943 by 17 
The aim is to understand the frequency of 17 in 225943.

Advancing to step 1:
2 divided by 17 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 17

Let's proceed to step 2:
If we divide 22 by 17, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we take 17 away from 22, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 17

Going ahead to step 3:
55 divided by 17 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 51 from 55 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 17

Going ahead to step 4:
49 divided by 17 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 132.0
Subtract 34 from 49 to get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 17

Let's proceed to step 5:
17 goes into 154 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1329.0
If we take 153 away from 154, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 17

On to step 6:
17 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 13290.0
If we take 0 away from 13, 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.

On to step 7:
If we divide 130 by 17, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 13290.7
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.

On to step 8:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13290.76
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 17, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 13290.764
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.

Moving on to step 10:
17 goes into 120 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 13290.7647
If we subtract 119 from 120, we 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 11:
If we divide 10 by 17, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 13290.7647
If we take 0 away from 10, we end up 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.

Going ahead to step 12:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13290.764705
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.

Moving on to step 13:
17 goes into 150 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 13290.7647058
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
When dividing 140 by 17, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 13290.76470588
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 13290.76470588 with a balance of 4e-09.
