We divide 426345 by 8
Let's see how many times 8 fits into 426345.

On to step 1:
8 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 8

Step 2:
The number 8 fits into 42 5 times, leaving a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
If we take 40 away from 42, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

Step 3:
8 can be fit into 26 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Deduct 24 from 26 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

On to step 4:
8 can be fit into 23 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 532.0
If we subtract 16 from 23, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 8

Advancing to step 5:
8 goes into 74 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 5329.0
Subtract 72 from 74 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 8

Step 6:
The number 8 fits into 25 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 53293.0
Subtract 24 from 25 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 8 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 53293.1
If we subtract 8 from 10, we get 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:
When dividing 20 by 8, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 53293.12
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.

Let's proceed to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53293.125
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.

Advancing to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53293.125
Deduct 0 from 0 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.

Moving on to step 11:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 53293.125
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.

Our division results in 53293.125 with a remaining 0.0.
