124435 divided by 17 
The aim is to understand the frequency of 17 in 124435.

Advancing to step 1:
1 divided by 17 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 17

Moving on to step 2:
17 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 17

Advancing to step 3:
17 can be fit into 124 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 119 away from 124, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 17

Moving on to step 4:
17 goes into 54 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 51 from 54 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 17

Going ahead to step 5:
The number 17 fits into 33 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 731.0
The remainder is 16 after subtracting 17 from 33.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 17

Advancing to step 6:
If we divide 165 by 17, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 7319.0
If we take 153 away from 165, 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 7:
When dividing 120 by 17, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7319.7
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.

On to step 8:
17 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7319.7
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.

Going ahead to step 9:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7319.705
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 7319.7058
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.

Step 11:
17 goes into 140 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7319.70588
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.

Our division results in 7319.70588 with a remaining 4e-06.
