We're dividing 351623 by 8 
Our goal is to divide 351623 by 8.

On to step 1:
8 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 8

Moving on to step 2:
35 divided by 8 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 3 after subtracting 32 from 35.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 8

Going ahead to step 3:
When dividing 31 by 8, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 7 after subtracting 24 from 31.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

Let's proceed to step 4:
The number 8 fits into 76 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 439.0
The remainder is 4 after subtracting 72 from 76.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 8

On to step 5:
If we divide 42 by 8, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 4395.0
Deduct 40 from 42 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

Step 6:
The number 8 fits into 23 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 43952.0
Subtracting 16 from 23 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
8 goes into 70 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 43952.8
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 43952.87
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 43952.875
Deduct 40 from 40 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.

Let's proceed to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43952.875
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 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43952.875
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.

After the division, we end up with 43952.875 and a remainder of 0.0.
