We look at the division of 423896 by 57 
Let's see how many times 57 fits into 423896.

On to step 1:
When dividing 4 by 57, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 57

Let's proceed to step 2:
57 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 57

Moving on to step 3:
The number 57 fits into 423 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 399 from 423 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 57

Moving on to step 4:
When dividing 248 by 57, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 20 after subtracting 228 from 248.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 57

Moving on to step 5:
57 can be fit into 209 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 743.0
If we take 171 away from 209, we end up with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 57

Advancing to step 6:
When dividing 386 by 57, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 7436.0
Subtract 342 from 386 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 57, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 7436.7
Deduct 399 from 440 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
The number 57 fits into 410 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7436.77
Deduct 399 from 410 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 7436.77 with a remainder of 0.011.
