Let's divide 420345 by 35
We want to figure out the number of times 420345 can be divided by 35.

Moving on to step 1:
The number 35 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 35

Step 2:
35 goes into 42 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 35 from 42 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 35

Going ahead to step 3:
When dividing 70 by 35, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 0 after subtracting 70 from 70.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 35

Let's proceed to step 4:
If we divide 3 by 35, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 35

Advancing to step 5:
If we divide 34 by 35, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 1200.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 35

Advancing to step 6:
345 divided by 35 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 12009.0
If we subtract 315 from 345, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 35 fits into 300 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 12009.8
If we take 280 away from 300, we end up 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.

Step 8:
The number 35 fits into 200 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12009.85
Deduct 175 from 200 and we're left 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:
If we divide 250 by 35, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 12009.857
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.

Going ahead to step 10:
50 divided by 35 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 12009.8571
Subtracting 35 from 50 leaves us 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.

Moving on to step 11:
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: 12009.85714
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.

Moving on to step 12:
35 goes into 100 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 12009.857142
Subtract 70 from 100 to get 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:
35 goes into 300 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 12009.8571428
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.

Going ahead to step 14:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12009.85714285
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.

Our division results in 12009.85714285 with a remaining 2.5e-08.
