139386 divided by 35 
The aim is to understand the frequency of 35 in 139386.

On to step 1:
35 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 35

Moving on to step 2:
The number 35 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 35

Let's proceed to step 3:
If we divide 139 by 35, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 105 from 139 leaves us with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 35

Moving on to step 4:
343 divided by 35 is 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 315 away from 343, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 35

On to step 5:
If we divide 288 by 35, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 398.0
If we take 280 away from 288, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 35

Advancing to step 6:
If we divide 86 by 35, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 3982.0
If we take 70 away from 86, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
35 goes into 160 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 3982.4
The remainder is 20 after subtracting 140 from 160.
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:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3982.45
Subtracting 175 from 200 leaves us 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.

Going ahead to step 9:
35 goes into 250 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 3982.457
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 10:
35 goes into 50 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3982.4571
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.

Let's proceed to step 11:
When dividing 150 by 35, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3982.45714
Subtracting 140 from 150 leaves us 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.

Let's proceed to step 12:
If we divide 100 by 35, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 3982.457142
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 13:
300 divided by 35 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3982.4571428
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.

Moving on to step 14:
35 can be fit into 200 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 3982.45714285
If we subtract 175 from 200, we 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.

Our division results in 3982.45714285 with a remaining 2.5e-08.
