We're dividing 42420869 by 428 
Let's see how many times 428 fits into 42420869.

Step 1:
4 divided by 428 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 428

Going ahead to step 2:
428 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 428

Going ahead to step 3:
428 can be fit into 424 0 times, resulting in a remainder of 424.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 424, we get 424.
Take the next digit (2) from the dividend and append it to 424, then repeat: 4242 / 428

Moving on to step 4:
If we divide 4242 by 428, we get 9 and a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3852 from 4242, we get 390.
Bring next digit (0) of the dividend behind the 390 and repeat the process: 3900 / 428

On to step 5:
3900 divided by 428 is 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 48 after subtracting 3852 from 3900.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 428

Let's proceed to step 6:
428 can be fit into 488 1 times, resulting in a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 991.0
Subtract 428 from 488 to get 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 428

Going ahead to step 7:
When dividing 606 by 428, we get 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 9911.0
The remainder is 178 after subtracting 428 from 606.
Take the next digit (9) from the dividend and append it to 178, then repeat: 1789 / 428

Moving on to step 8:
The number 428 fits into 1789 4 times, leaving a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 99114.0
Subtract 1712 from 1789 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
428 can be fit into 770 1 times, resulting in a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 99114.1
Subtract 428 from 770 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
When dividing 3420 by 428, we get 7 with a remainder of 424.
The number 7 becomes the next digit in our result. 
Result so far: 99114.17
If we take 2996 away from 3420, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 11:
428 can be fit into 4240 9 times, resulting in a remainder of 388.
Put 9 as the next digit of the answer. 
Result so far: 99114.179
Subtracting 3852 from 4240 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 12:
If we divide 3880 by 428, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 99114.1799
Subtract 3852 from 3880 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 99114.1799 with a balance of 0.00028.
