We divide 4389370 by 330
We want to figure out the number of times 4389370 can be divided by 330.

On to step 1:
If we divide 4 by 330, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 330

On to step 2:
When dividing 43 by 330, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 330

Step 3:
330 goes into 438 1 times with a remainder of 108.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 330 from 438 to get 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 330

Moving on to step 4:
330 goes into 1089 3 times with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 990 from 1089 leaves us with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 330

Step 5:
993 divided by 330 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 990 away from 993, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 330

Step 6:
If we divide 37 by 330, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 1330.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 330

Step 7:
370 divided by 330 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 13301.0
If we take 330 away from 370, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
If we divide 400 by 330, we get 1 and a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 13301.1
If we take 330 away from 400, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
If we divide 700 by 330, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 13301.12
Subtracting 660 from 700 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 330, we get 1 and a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 13301.121
Deduct 330 from 400 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 330, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 13301.1212
Deduct 660 from 700 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 330 fits into 400 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 13301.12121
Subtracting 330 from 400 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
330 goes into 700 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 13301.121212
If we subtract 660 from 700, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
330 goes into 400 1 times with a remainder of 70.
The next digit of our result is 1. 
Result so far: 13301.1212121
If we subtract 330 from 400, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
When dividing 700 by 330, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 13301.12121212
Subtracting 660 from 700 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 13301.12121212 with a remaining 4e-08.
