Let's divide 42850335 by 390
Let's see how many times 390 fits into 42850335.

Going ahead to step 1:
4 divided by 390 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 390

Let's proceed to step 2:
When dividing 42 by 390, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 390

Going ahead to step 3:
When dividing 428 by 390, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 390 from 428 to get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 390

Step 4:
385 divided by 390 is 0 with a remainder of 385.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 385 leaves us with 385.
Grab the next digit (0) from the dividend, add it to 385, then carry on: 3850 / 390

Moving on to step 5:
390 can be fit into 3850 9 times, resulting in a remainder of 340.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Deduct 3510 from 3850 and we're left with 340.
Bring next digit (3) of the dividend behind the 340 and repeat the process: 3403 / 390

On to step 6:
When dividing 3403 by 390, we get 8 with a remainder of 283.
Put 8 as the next digit of the answer. 
Result so far: 1098.0
The remainder is 283 after subtracting 3120 from 3403.
Take the next digit (3) from the dividend and append it to 283, then repeat: 2833 / 390

On to step 7:
When dividing 2833 by 390, we get 7 with a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 10987.0
If we subtract 2730 from 2833, we get 103.
Fetch the next digit (5) from the dividend, attach it to 103 and continue: 1035 / 390

Going ahead to step 8:
390 can be fit into 1035 2 times, resulting in a remainder of 255.
Record the quotient 2 as the next digit in the result. 
Result so far: 109872.0
Subtract 780 from 1035 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 9:
390 goes into 2550 6 times with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 109872.6
If we subtract 2340 from 2550, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
The number 390 fits into 2100 5 times, leaving a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 109872.65
Subtracting 1950 from 2100 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
The number 390 fits into 1500 3 times, leaving a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 109872.653
Subtract 1170 from 1500 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 12:
3300 divided by 390 is 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 109872.6538
Subtract 3120 from 3300 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.

Let's proceed to step 13:
If we divide 1800 by 390, we get 4 and a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 109872.65384
Deduct 1560 from 1800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
390 goes into 2400 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 109872.653846
The remainder is 60 after subtracting 2340 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
390 goes into 600 1 times with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 109872.6538461
If we take 390 away from 600, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 16:
390 goes into 2100 5 times with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 109872.65384615
If we take 1950 away from 2100, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 109872.65384615 with a remaining 1.5e-07.
