We look at the division of 866244 by 35 
The aim is to understand the frequency of 35 in 866244.

Step 1:
When dividing 8 by 35, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 35

Going ahead to step 2:
When dividing 86 by 35, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 70 from 86 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 35

On to step 3:
When dividing 166 by 35, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 140 away from 166, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 35

Step 4:
When dividing 262 by 35, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
If we take 245 away from 262, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 35

Going ahead to step 5:
174 divided by 35 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 2474.0
Deduct 140 from 174 and we're left with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 35

Step 6:
The number 35 fits into 344 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 24749.0
If we take 315 away from 344, we end up with 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.
Record the quotient 8 as the next digit in the result. 
Result so far: 24749.8
Subtract 280 from 290 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 35 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 24749.82
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.

Advancing to step 9:
300 divided by 35 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 24749.828
Deduct 280 from 300 and we're left 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.

Moving on to step 10:
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: 24749.8285
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.

Moving on to step 11:
When dividing 250 by 35, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 24749.82857
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.

Advancing to step 12:
The number 35 fits into 50 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 24749.828571
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.

On to step 13:
The number 35 fits into 150 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 24749.8285714
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:
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: 24749.82857142
Subtracting 70 from 100 leaves us 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.

The final outcome is 24749.82857142, with a leftover of 3e-08.
