337989 ÷ 35 
The aim is to understand the frequency of 35 in 337989.

Let's proceed to step 1:
3 divided by 35 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 35

Advancing to step 2:
35 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 35

Going ahead to step 3:
35 can be fit into 337 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 315 away from 337, we end up with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 35

Moving on to step 4:
The number 35 fits into 229 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 210 from 229, we get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 35

Going ahead to step 5:
If we divide 198 by 35, we get 5 and a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
The remainder is 23 after subtracting 175 from 198.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 35

On to step 6:
239 divided by 35 is 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 9656.0
Subtract 210 from 239 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 35, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 9656.8
The remainder is 10 after subtracting 280 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 35, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 9656.82
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.

Moving on to step 9:
300 divided by 35 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 9656.828
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 10:
200 divided by 35 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9656.8285
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.

Moving on to step 11:
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: 9656.82857
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.

Let's proceed to step 12:
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: 9656.828571
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.

Step 13:
35 goes into 150 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 9656.8285714
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.

Moving on to step 14:
If we divide 100 by 35, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 9656.82857142
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.

After the division, we end up with 9656.82857142 and a remainder of 3e-08.
