We're dividing 428420 by 35 
We're looking to find how many times 35 goes into 428420.

Advancing to step 1:
The number 35 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 35

Advancing to step 2:
35 goes into 42 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 35 from 42 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 35

Step 3:
If we divide 78 by 35, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 70 from 78 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 35

Advancing to step 4:
The number 35 fits into 84 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Deduct 70 from 84 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 35

Let's proceed to step 5:
35 can be fit into 142 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1224.0
Deduct 140 from 142 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 35

Advancing to step 6:
35 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12240.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
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: 12240.5
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.

Step 8:
250 divided by 35 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 12240.57
If we take 245 away from 250, we end up 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.

On to step 9:
The number 35 fits into 50 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 12240.571
The remainder is 15 after subtracting 35 from 50.
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 10:
35 goes into 150 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 12240.5714
The remainder is 10 after subtracting 140 from 150.
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 11:
35 goes into 100 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 12240.57142
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.

Step 12:
If we divide 300 by 35, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 12240.571428
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
If we divide 200 by 35, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12240.5714285
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 14:
The number 35 fits into 250 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 12240.57142857
If we take 245 away from 250, we end up 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.

In conclusion, the division gives 12240.57142857 with a balance of 5e-09.
