We're dividing 399169 by 35 
The aim is to understand the frequency of 35 in 399169.

On to step 1:
35 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 35

Going ahead to step 2:
When dividing 39 by 35, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 35 from 39 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 35

Let's proceed to step 3:
When dividing 49 by 35, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 35 from 49 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 35

Advancing to step 4:
141 divided by 35 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we subtract 140 from 141, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 35

Step 5:
When dividing 16 by 35, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
Subtract 0 from 16 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 35

Going ahead to step 6:
If we divide 169 by 35, we get 4 and a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 11404.0
Subtract 140 from 169 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 35, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 11404.8
If we take 280 away from 290, 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.

On to step 8:
If we divide 100 by 35, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 11404.82
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 9:
The number 35 fits into 300 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 11404.828
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.

Going ahead to step 10:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11404.8285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
When dividing 250 by 35, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 11404.82857
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.

Going ahead to step 12:
50 divided by 35 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11404.828571
Subtract 35 from 50 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.

Step 13:
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: 11404.8285714
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.

Moving on to step 14:
35 goes into 100 2 times with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 11404.82857142
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.

The quotient of the division is 11404.82857142, and the remainder is 3e-08.
