Let's divide 28353860 by 439
We want to figure out the number of times 28353860 can be divided by 439.

On to step 1:
2 divided by 439 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 439

Moving on to step 2:
When dividing 28 by 439, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 439

Let's proceed to step 3:
When dividing 283 by 439, we get 0 with a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 283 and we're left with 283.
Bring next digit (5) of the dividend behind the 283 and repeat the process: 2835 / 439

Going ahead to step 4:
The number 439 fits into 2835 6 times, leaving a remainder of 201.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 2634 from 2835 and we're left with 201.
Append the next digit (3) from the dividend to 201 and continue with: 2013 / 439

Step 5:
If we divide 2013 by 439, we get 4 and a remainder of 257.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 1756 from 2013, we get 257.
Include the next digit (8) from the dividend after 257, then repeat: 2578 / 439

Advancing to step 6:
439 goes into 2578 5 times with a remainder of 383.
Put 5 as the next digit of the answer. 
Result so far: 645.0
Deduct 2195 from 2578 and we're left with 383.
Include the next digit (6) from the dividend after 383, then repeat: 3836 / 439

Moving on to step 7:
The number 439 fits into 3836 8 times, leaving a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 6458.0
Subtract 3512 from 3836 to get 324.
Fetch the next digit (0) from the dividend, attach it to 324 and continue: 3240 / 439

Going ahead to step 8:
If we divide 3240 by 439, we get 7 and a remainder of 167.
Record the quotient 7 as the next digit in the result. 
Result so far: 64587.0
The remainder is 167 after subtracting 3073 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
When dividing 1670 by 439, we get 3 with a remainder of 353.
Use 3 as the next digit of our solution. 
Result so far: 64587.3
Deduct 1317 from 1670 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 10:
439 can be fit into 3530 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 64587.38
Subtracting 3512 from 3530 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
When dividing 180 by 439, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 64587.38
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 12:
439 goes into 1800 4 times with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 64587.3804
Subtract 1756 from 1800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
439 can be fit into 440 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 64587.38041
If we take 439 away from 440, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
When dividing 10 by 439, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 64587.38041
If we subtract 0 from 10, we get 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 15:
When dividing 100 by 439, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 64587.38041
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 64587.38041, with a leftover of 1e-06.
