We look at the division of 3355406 by 320 
Let's see how many times 320 fits into 3355406.

Going ahead to step 1:
When dividing 3 by 320, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 320

Moving on to step 2:
320 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 320

On to step 3:
320 goes into 335 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 320 from 335, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 320

Let's proceed to step 4:
320 can be fit into 155 0 times, resulting in a remainder of 155.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 155 leaves us with 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 320

Step 5:
320 can be fit into 1554 4 times, resulting in a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 1280 from 1554 to get 274.
Include the next digit (0) from the dividend after 274, then repeat: 2740 / 320

Going ahead to step 6:
320 goes into 2740 8 times with a remainder of 180.
The next digit of our result is 8. 
Result so far: 1048.0
If we subtract 2560 from 2740, we get 180.
Grab the next digit (6) from the dividend, add it to 180, then carry on: 1806 / 320

Step 7:
1806 divided by 320 is 5 with a remainder of 206.
Write down 5 as next digit of the result. 
Result so far: 10485.0
The remainder is 206 after subtracting 1600 from 1806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 8:
320 can be fit into 2060 6 times, resulting in a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 10485.6
The remainder is 140 after subtracting 1920 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
1400 divided by 320 is 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 10485.64
The remainder is 120 after subtracting 1280 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
If we divide 1200 by 320, we get 3 and a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 10485.643
If we subtract 960 from 1200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
When dividing 2400 by 320, we get 7 with a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 10485.6437
If we take 2240 away from 2400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
320 goes into 1600 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10485.64375
Deduct 1600 from 1600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10485.64375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10485.64375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10485.64375 with a remaining 0.0.
