We're dividing 523401 by 8 
We want to divide 523401 by 8.

On to step 1:
8 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 8

Moving on to step 2:
8 goes into 52 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 48 from 52 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 8

Advancing to step 3:
8 can be fit into 43 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 40 from 43 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 8

Going ahead to step 4:
The number 8 fits into 34 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 654.0
If we take 32 away from 34, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

Advancing to step 5:
8 goes into 20 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6542.0
If we subtract 16 from 20, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 8

On to step 6:
41 divided by 8 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 65425.0
If we subtract 40 from 41, we 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.

Advancing to step 7:
When dividing 10 by 8, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 65425.1
If we take 8 away from 10, 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:
8 goes into 20 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 65425.12
If we subtract 16 from 20, 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:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 65425.125
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.

Advancing 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: 65425.125
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.

Advancing to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 65425.125
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.

The quotient of the division is 65425.125, and the remainder is 0.0.
