Let's divide 13907 by 35
The aim is to understand the frequency of 35 in 13907.

Going ahead to step 1:
35 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 35

Going ahead to step 2:
When dividing 13 by 35, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 35

Step 3:
35 goes into 139 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 105 from 139 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 35

Step 4:
If we divide 340 by 35, we get 9 and a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 315 from 340, we get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 35

Advancing to step 5:
35 goes into 257 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 397.0
Subtracting 245 from 257 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 6:
35 can be fit into 120 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 397.3
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 35 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 397.34
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 8:
The number 35 fits into 100 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 397.342
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.

On to step 9:
The number 35 fits into 300 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 397.3428
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.

Moving on to step 10:
35 can be fit into 200 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 397.34285
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.

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: 397.342857
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.

Going ahead to step 12:
The number 35 fits into 50 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 397.3428571
If we subtract 35 from 50, we get 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 13:
If we divide 150 by 35, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 397.34285714
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 397.34285714 and a remainder of 1e-08.
