We look at the division of 428115 by 99 
Let's see how many times 99 fits into 428115.

Moving on to step 1:
The number 99 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 99

Let's proceed to step 2:
When dividing 42 by 99, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 99

Let's proceed to step 3:
If we divide 428 by 99, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 396 from 428 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 99

On to step 4:
99 can be fit into 321 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 297 from 321, we get 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 99

Moving on to step 5:
99 goes into 241 2 times with a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 432.0
Subtract 198 from 241 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 99

Step 6:
435 divided by 99 is 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 4324.0
If we subtract 396 from 435, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
If we divide 390 by 99, we get 3 and a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 4324.3
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 8:
If we divide 930 by 99, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 4324.39
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
99 can be fit into 390 3 times, resulting in a remainder of 93.
The next digit of our result is 3. 
Result so far: 4324.393
If we subtract 297 from 390, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 10:
When dividing 930 by 99, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 4324.3939
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
390 divided by 99 is 3 with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 4324.39393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 12:
99 can be fit into 930 9 times, resulting in a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 4324.393939
If we subtract 891 from 930, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
If we divide 390 by 99, we get 3 and a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 4324.3939393
Subtracting 297 from 390 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 14:
99 can be fit into 930 9 times, resulting in a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 4324.39393939
The remainder is 39 after subtracting 891 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 4324.39393939 and a remainder of 3.9e-08.
