We look at the division of 399509 by 35 
We want to figure out the number of times 399509 can be divided by 35.

Moving on to step 1:
3 divided by 35 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 35

Advancing to step 2:
35 goes into 39 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 35 from 39 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 35

Moving on to step 3:
If we divide 49 by 35, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 35 from 49 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 35

Going ahead to step 4:
If we divide 145 by 35, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we subtract 140 from 145, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 35

On to step 5:
If we divide 50 by 35, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1141.0
Deduct 35 from 50 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 35

Going ahead to step 6:
When dividing 159 by 35, we get 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 11414.0
If we subtract 140 from 159, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 35 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 11414.5
The remainder is 15 after subtracting 175 from 190.
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 8:
150 divided by 35 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 11414.54
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.

Advancing to step 9:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 11414.542
Subtracting 70 from 100 leaves us 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 10:
35 goes into 300 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 11414.5428
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 11:
When dividing 200 by 35, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11414.54285
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.

Let's proceed to step 12:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 11414.542857
Deduct 245 from 250 and we're left 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 13:
If we divide 50 by 35, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 11414.5428571
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.

Moving on to step 14:
If we divide 150 by 35, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 11414.54285714
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.

The final result is 11414.54285714 with a remainder of 1e-08.
