We're dividing 863600 by 35 
The aim is to understand the frequency of 35 in 863600.

On to step 1:
35 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 35

Advancing to step 2:
The number 35 fits into 86 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 70 away from 86, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 35

Moving on to step 3:
163 divided by 35 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 140 from 163, we get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 35

Step 4:
35 can be fit into 236 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 246.0
Subtract 210 from 236 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 35

Step 5:
When dividing 260 by 35, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 2467.0
Subtracting 245 from 260 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 35

Moving on to step 6:
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: 24674.0
If we take 140 away from 150, we end up 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.

Advancing to step 7:
When dividing 100 by 35, we get 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 24674.2
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.

Moving on to step 8:
35 goes into 300 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 24674.28
Subtract 280 from 300 to 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.

Step 9:
When dividing 200 by 35, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 24674.285
If we take 175 away from 200, we end up 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 10:
250 divided by 35 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 24674.2857
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.

Let's proceed to step 11:
When dividing 50 by 35, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 24674.28571
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.

Going ahead to step 12:
If we divide 150 by 35, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 24674.285714
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.

Going ahead to step 13:
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: 24674.2857142
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.

Step 14:
35 goes into 300 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 24674.28571428
Subtracting 280 from 300 leaves us 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.

The final outcome is 24674.28571428, with a leftover of 2e-08.
