We look at the division of 34393905 by 439 
We're looking to find how many times 439 goes into 34393905.

Moving on to step 1:
The number 439 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 439

Step 2:
439 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 439

Advancing to step 3:
439 can be fit into 343 0 times, resulting in a remainder of 343.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 343 to get 343.
Bring next digit (9) of the dividend behind the 343 and repeat the process: 3439 / 439

On to step 4:
If we divide 3439 by 439, we get 7 and a remainder of 366.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 3073 from 3439, we get 366.
Append the next digit (3) from the dividend to 366 and continue with: 3663 / 439

Advancing to step 5:
439 goes into 3663 8 times with a remainder of 151.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 151 after subtracting 3512 from 3663.
Grab the next digit (9) from the dividend, add it to 151, then carry on: 1519 / 439

Going ahead to step 6:
The number 439 fits into 1519 3 times, leaving a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 783.0
Subtracting 1317 from 1519 leaves us with 202.
Include the next digit (0) from the dividend after 202, then repeat: 2020 / 439

Going ahead to step 7:
439 goes into 2020 4 times with a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 7834.0
Subtract 1756 from 2020 to get 264.
Fetch the next digit (5) from the dividend, attach it to 264 and continue: 2645 / 439

Moving on to step 8:
If we divide 2645 by 439, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 78346.0
If we take 2634 away from 2645, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 439, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 78346.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
439 can be fit into 1100 2 times, resulting in a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 78346.02
Subtract 878 from 1100 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 11:
439 can be fit into 2220 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 78346.025
If we subtract 2195 from 2220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
When dividing 250 by 439, we get 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 78346.025
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
When dividing 2500 by 439, we get 5 with a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 78346.02505
If we take 2195 away from 2500, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 14:
When dividing 3050 by 439, we get 6 with a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 78346.025056
The remainder is 416 after subtracting 2634 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 15:
439 goes into 4160 9 times with a remainder of 209.
Record the quotient 9 as the next digit in the result. 
Result so far: 78346.0250569
Subtracting 3951 from 4160 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 16:
439 can be fit into 2090 4 times, resulting in a remainder of 334.
Record the quotient 4 as the next digit in the result. 
Result so far: 78346.02505694
Deduct 1756 from 2090 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Our division results in 78346.02505694 with a remaining 3.34e-07.
