3920439 ÷ 535 
We want to figure out the number of times 3920439 can be divided by 535.

On to step 1:
535 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 535

On to step 2:
535 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 535

Advancing to step 3:
If we divide 392 by 535, we get 0 and a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Fetch the next digit (0) from the dividend, attach it to 392 and continue: 3920 / 535

Let's proceed to step 4:
3920 divided by 535 is 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 3745 away from 3920, we end up with 175.
Bring next digit (4) of the dividend behind the 175 and repeat the process: 1754 / 535

Going ahead to step 5:
The number 535 fits into 1754 3 times, leaving a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 1605 from 1754, we get 149.
Bring next digit (3) of the dividend behind the 149 and repeat the process: 1493 / 535

Going ahead to step 6:
1493 divided by 535 is 2 with a remainder of 423.
The next digit of our result is 2. 
Result so far: 732.0
Subtracting 1070 from 1493 leaves us with 423.
Append the next digit (9) from the dividend to 423 and continue with: 4239 / 535

On to step 7:
If we divide 4239 by 535, we get 7 and a remainder of 494.
Record the quotient 7 as the next digit in the result. 
Result so far: 7327.0
Subtracting 3745 from 4239 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 8:
535 goes into 4940 9 times with a remainder of 125.
The next digit of our result is 9. 
Result so far: 7327.9
Subtract 4815 from 4940 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
When dividing 1250 by 535, we get 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 7327.92
If we subtract 1070 from 1250, we 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 10:
The number 535 fits into 1800 3 times, leaving a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 7327.923
Subtracting 1605 from 1800 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 11:
1950 divided by 535 is 3 with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 7327.9233
The remainder is 345 after subtracting 1605 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 7327.9233, with a leftover of 0.00345.
