We're dividing 312238 by 74 
Let's see how many times 74 fits into 312238.

Advancing to step 1:
74 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 74

On to step 2:
The number 74 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 74

On to step 3:
74 goes into 312 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 296 away from 312, we end up with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 74

Going ahead to step 4:
162 divided by 74 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 148 from 162 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 74

Going ahead to step 5:
The number 74 fits into 143 1 times, leaving a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Deduct 74 from 143 and we're left with 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 74

Let's proceed to step 6:
When dividing 698 by 74, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 4219.0
If we take 666 away from 698, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 74, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4219.4
Deduct 296 from 320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
When dividing 240 by 74, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 4219.43
If we take 222 away from 240, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
180 divided by 74 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4219.432
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
74 goes into 320 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4219.4324
Subtract 296 from 320 to get 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 11:
74 goes into 240 3 times with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 4219.43243
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
74 goes into 180 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 4219.432432
If we subtract 148 from 180, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
74 goes into 320 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4219.4324324
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 74, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 4219.43243243
Deduct 222 from 240 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 4219.43243243 and a remainder of 1.8e-08.
