We're dividing 405357 by 8 
Our goal is to divide 405357 by 8.

Moving on to step 1:
8 can be fit into 4 0 times, resulting in 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.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

Step 2:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 8

Going ahead to step 3:
8 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 8

Step 4:
When dividing 53 by 8, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 506.0
Subtract 48 from 53 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 8

Advancing to step 5:
55 divided by 8 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 5066.0
If we take 48 away from 55, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 8

Going ahead to step 6:
When dividing 77 by 8, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 50669.0
If we take 72 away from 77, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 8, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 50669.6
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 8 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 50669.62
If we take 16 away from 20, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 50669.625
Subtracting 40 from 40 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.

Going ahead to step 10:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50669.625
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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50669.625
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 50669.625 with a remaining 0.0.
