We look at the division of 643013 by 35 
We want to figure out the number of times 643013 can be divided by 35.

Going ahead to step 1:
The number 35 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 35

Step 2:
The number 35 fits into 64 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 35 from 64 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 35

Advancing to step 3:
293 divided by 35 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 280 from 293 and we're left with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 35

Let's proceed to step 4:
130 divided by 35 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we take 105 away from 130, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 35

Advancing to step 5:
If we divide 251 by 35, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 1837.0
Subtracting 245 from 251 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 35

Advancing to step 6:
35 can be fit into 63 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 18371.0
Deduct 35 from 63 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
When dividing 280 by 35, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18371.8
The remainder is 0 after subtracting 280 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 35 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 18371.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
35 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18371.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 18371.8 with a remaining 0.0.
