We look at the division of 42876 by 35 
The aim is to understand the frequency of 35 in 42876.

Advancing to step 1:
If we divide 4 by 35, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 35

On to step 2:
If we divide 42 by 35, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 35 from 42, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 35

On to step 3:
If we divide 78 by 35, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 70 away from 78, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 35

Step 4:
The number 35 fits into 87 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
The remainder is 17 after subtracting 70 from 87.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 35

Advancing to step 5:
35 goes into 176 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Subtract 175 from 176 to 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.

Going ahead to step 6:
When dividing 10 by 35, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1225.0
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.

Moving on to step 7:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 1225.02
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 35, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 1225.028
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1225.0285
If we subtract 175 from 200, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1225.02857
If we take 245 away from 250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 35, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1225.028571
Subtracting 35 from 50 leaves us 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.

Let's proceed to step 12:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1225.0285714
Subtracting 140 from 150 leaves us 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 13:
100 divided by 35 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 1225.02857142
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 1225.02857142, and the remainder is 3e-08.
