We divide 660592 by 35
The aim is to understand the frequency of 35 in 660592.

Step 1:
The number 35 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 35

Going ahead to step 2:
If we divide 66 by 35, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 35 from 66 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 35

Let's proceed to step 3:
35 goes into 310 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 280 from 310 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 35

On to step 4:
The number 35 fits into 305 8 times, leaving a remainder of 25.
The next digit of our result is 8. 
Result so far: 188.0
The remainder is 25 after subtracting 280 from 305.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 35

Moving on to step 5:
259 divided by 35 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 1887.0
If we subtract 245 from 259, we get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 35

Let's proceed to step 6:
35 goes into 142 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 18874.0
Deduct 140 from 142 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 35, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 18874.0
If we subtract 0 from 20, we 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.

Let's proceed to step 8:
200 divided by 35 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 18874.05
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.

Advancing to step 9:
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: 18874.057
If we take 245 away from 250, we end up 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.

On to step 10:
35 goes into 50 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 18874.0571
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.

Advancing to step 11:
When dividing 150 by 35, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 18874.05714
Subtract 140 from 150 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.

Moving on to step 12:
When dividing 100 by 35, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 18874.057142
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.

Step 13:
If we divide 300 by 35, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 18874.0571428
If we subtract 280 from 300, we 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.

Advancing to step 14:
The number 35 fits into 200 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18874.05714285
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.

After the division, we end up with 18874.05714285 and a remainder of 2.5e-08.
