721830 divided by 35 
The aim is to understand the frequency of 35 in 721830.

Moving on to step 1:
7 divided by 35 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 35

On to step 2:
35 can be fit into 72 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 70 away from 72, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 35

Advancing to step 3:
When dividing 21 by 35, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 35

On to step 4:
218 divided by 35 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 206.0
Subtract 210 from 218 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 35

Let's proceed to step 5:
If we divide 83 by 35, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2062.0
If we take 70 away from 83, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 35

Let's proceed to step 6:
When dividing 130 by 35, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 20623.0
Deduct 105 from 130 and we're left 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 7:
250 divided by 35 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 20623.7
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 8:
If we divide 50 by 35, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 20623.71
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 9:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 20623.714
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 10:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 20623.7142
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
35 goes into 300 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 20623.71428
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.

Moving on to step 12:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 20623.714285
The remainder is 25 after subtracting 175 from 200.
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 13:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 20623.7142857
If we subtract 245 from 250, we 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.

Moving on to step 14:
35 can be fit into 50 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 20623.71428571
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 20623.71428571 with a remaining 1.5e-08.
