We're dividing 71938 by 17 
The aim is to understand the frequency of 17 in 71938.

Going ahead to step 1:
When dividing 7 by 17, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 17

Step 2:
17 goes into 71 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 68 from 71.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 17

Moving on to step 3:
The number 17 fits into 39 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 34 away from 39, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 17

Advancing to step 4:
If we divide 53 by 17, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 423.0
If we subtract 51 from 53, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 17

Step 5:
When dividing 28 by 17, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 4231.0
Deduct 17 from 28 and we're left 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.

Advancing to step 6:
110 divided by 17 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4231.6
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.

Going ahead to step 7:
17 goes into 80 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4231.64
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.

Advancing to step 8:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 4231.647
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.

Going ahead to step 9:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4231.647
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.

Step 10:
100 divided by 17 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4231.64705
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.

Advancing to step 11:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 4231.647058
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.

On to step 12:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 4231.6470588
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.

After the division, we end up with 4231.6470588 and a remainder of 4e-08.
