We're dividing 423964 by 94 
We want to figure out the number of times 423964 can be divided by 94.

Going ahead to step 1:
94 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 94

Going ahead to step 2:
The number 94 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 94

On to step 3:
If we divide 423 by 94, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 376 from 423, we get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 94

Advancing to step 4:
If we divide 479 by 94, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 470 away from 479, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 94

Going ahead to step 5:
The number 94 fits into 96 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 451.0
If we take 94 away from 96, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 94

Advancing to step 6:
94 goes into 24 0 times with a remainder of 24.
The next digit of our result is 0. 
Result so far: 4510.0
The remainder is 24 after subtracting 0 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
240 divided by 94 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 4510.2
If we take 188 away from 240, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
The number 94 fits into 520 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4510.25
The remainder is 50 after subtracting 470 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 94 fits into 500 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 4510.255
Subtract 470 from 500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 4510.255 with a remainder of 0.003.
