We look at the division of 4485428 by 439 
Our goal is to divide 4485428 by 439.

Going ahead to step 1:
439 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 439

Let's proceed to step 2:
If we divide 44 by 439, we get 0 and a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 439

Going ahead to step 3:
When dividing 448 by 439, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 439 from 448.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 439

Moving on to step 4:
The number 439 fits into 95 0 times, leaving a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 95, we end up with 95.
Bring next digit (4) of the dividend behind the 95 and repeat the process: 954 / 439

Going ahead to step 5:
When dividing 954 by 439, we get 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
The remainder is 76 after subtracting 878 from 954.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 439

Moving on to step 6:
If we divide 762 by 439, we get 1 and a remainder of 323.
Use 1 as the next digit of our solution. 
Result so far: 1021.0
The remainder is 323 after subtracting 439 from 762.
Fetch the next digit (8) from the dividend, attach it to 323 and continue: 3238 / 439

Going ahead to step 7:
When dividing 3238 by 439, we get 7 with a remainder of 165.
Put 7 as the next digit of the answer. 
Result so far: 10217.0
If we subtract 3073 from 3238, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 8:
When dividing 1650 by 439, we get 3 with a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 10217.3
Subtracting 1317 from 1650 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 9:
The number 439 fits into 3330 7 times, leaving a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 10217.37
If we subtract 3073 from 3330, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 10:
439 goes into 2570 5 times with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 10217.375
If we take 2195 away from 2570, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 11:
3750 divided by 439 is 8 with a remainder of 238.
The next digit of our result is 8. 
Result so far: 10217.3758
If we take 3512 away from 3750, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 12:
2380 divided by 439 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 10217.37585
If we subtract 2195 from 2380, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 13:
1850 divided by 439 is 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 10217.375854
The remainder is 94 after subtracting 1756 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 14:
439 goes into 940 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 10217.3758542
Subtract 878 from 940 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 15:
The number 439 fits into 620 1 times, leaving a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 10217.37585421
Deduct 439 from 620 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The final result is 10217.37585421 with a remainder of 1.81e-07.
