We look at the division of 50687 by 35 
The aim is to understand the frequency of 35 in 50687.

Step 1:
If we divide 5 by 35, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 35

On to step 2:
The number 35 fits into 50 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 35 from 50.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 35

Moving on to step 3:
35 goes into 156 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 140 from 156 and we're left with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 35

Step 4:
The number 35 fits into 168 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we subtract 140 from 168, we get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 35

Moving on to step 5:
287 divided by 35 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1448.0
Deduct 280 from 287 and we're left 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 6:
The number 35 fits into 70 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 1448.2
Subtract 70 from 70 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 35, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1448.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 35, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1448.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1448.2 with a remaining 0.0.
