We look at the division of 802850 by 35 
The aim is to understand the frequency of 35 in 802850.

On to step 1:
8 divided by 35 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 35

Let's proceed to step 2:
35 can be fit into 80 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 70 from 80, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 35

Step 3:
If we divide 102 by 35, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 70 from 102 to get 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 35

Going ahead to step 4:
35 goes into 328 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
Subtract 315 from 328 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 35

On to step 5:
When dividing 135 by 35, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2293.0
The remainder is 30 after subtracting 105 from 135.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 35

Going ahead to step 6:
When dividing 300 by 35, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 22938.0
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 22938.5
Subtracting 175 from 200 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 35, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 22938.57
Subtracting 245 from 250 leaves us 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.

Let's proceed to step 9:
When dividing 50 by 35, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 22938.571
Deduct 35 from 50 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.

Step 10:
35 goes into 150 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 22938.5714
Deduct 140 from 150 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 11:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 22938.57142
Deduct 70 from 100 and we're left 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.

Let's proceed to step 12:
35 can be fit into 300 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 22938.571428
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 22938.5714285
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 14:
If we divide 250 by 35, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 22938.57142857
Subtract 245 from 250 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 22938.57142857, with a leftover of 5e-09.
