981373 ÷ 35 
The aim is to understand the frequency of 35 in 981373.

Going ahead to step 1:
If we divide 9 by 35, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 35

Step 2:
The number 35 fits into 98 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 70 from 98 and we're left with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 35

Going ahead to step 3:
If we divide 281 by 35, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 280 from 281, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 35

Let's proceed to step 4:
If we divide 13 by 35, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 35

Step 5:
137 divided by 35 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 2803.0
Subtracting 105 from 137 leaves us with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 35

On to step 6:
323 divided by 35 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 28039.0
If we take 315 away from 323, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 35, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 28039.2
Deduct 70 from 80 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 8:
If we divide 100 by 35, we get 2 and a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 28039.22
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.

After the division, we end up with 28039.22 and a remainder of 0.03.
