Let's divide 845339 by 1
We want to figure out the number of times 845339 can be divided by 1.

Step 1:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Advancing to step 3:
If we divide 5 by 1, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 845.0
If we subtract 5 from 5, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Going ahead to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 8453.0
If we subtract 3 from 3, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Advancing to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 84533.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 6:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 845339.0
The remainder is 0 after subtracting 9 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 845339.0
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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 845339.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 845339.0 and a remainder of 0.0.
