Let's divide 161925 by 35
The aim is to understand the frequency of 35 in 161925.

Advancing to step 1:
If we divide 1 by 35, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 35

Advancing to step 2:
35 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 35

Step 3:
The number 35 fits into 161 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 140 from 161 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 35

Advancing to step 4:
When dividing 219 by 35, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 210 from 219, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 35

Step 5:
If we divide 92 by 35, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 462.0
Deduct 70 from 92 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 35

On to step 6:
35 can be fit into 225 6 times, resulting in a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 4626.0
If we take 210 away from 225, we end up 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.

Advancing to step 7:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4626.4
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.

Moving on to step 8:
When dividing 100 by 35, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 4626.42
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

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: 4626.428
If we take 280 away from 300, we end up 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.

On to step 10:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4626.4285
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.

Moving on to step 11:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4626.42857
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.

Advancing to step 12:
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: 4626.428571
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 can be fit into 150 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 4626.4285714
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.

Advancing to step 14:
100 divided by 35 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 4626.42857142
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.

Our division results in 4626.42857142 with a remaining 3e-08.
