We look at the division of 72853070 by 35 
The aim is to understand the frequency of 35 in 72853070.

Advancing to step 1:
When dividing 7 by 35, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 35

Step 2:
When dividing 72 by 35, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 70 from 72 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 35

Going ahead to step 3:
35 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 28 to get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 35

Advancing to step 4:
35 can be fit into 285 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Subtracting 280 from 285 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 35

On to step 5:
If we divide 53 by 35, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 2081.0
Subtracting 35 from 53 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 35

Moving on to step 6:
The number 35 fits into 180 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 20815.0
Subtract 175 from 180 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 35

Going ahead to step 7:
57 divided by 35 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 208151.0
If we take 35 away from 57, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 35

On to step 8:
The number 35 fits into 220 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 2081516.0
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
35 can be fit into 100 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2081516.2
If we take 70 away from 100, we end up 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.

Going ahead to step 10:
When dividing 300 by 35, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 2081516.28
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.

On to step 11:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2081516.285
Subtract 175 from 200 to 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.

Advancing to step 12:
35 goes into 250 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 2081516.2857
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.

Step 13:
If we divide 50 by 35, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 2081516.28571
If we subtract 35 from 50, we 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.

Let's proceed to step 14:
When dividing 150 by 35, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2081516.285714
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.

On to step 15:
If we divide 100 by 35, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2081516.2857142
If we subtract 70 from 100, we 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.

Let's proceed to step 16:
When dividing 300 by 35, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 2081516.28571428
If we subtract 280 from 300, we 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.

The quotient of the division is 2081516.28571428, and the remainder is 2e-08.
