We're dividing 399488 by 76 
We want to divide 399488 by 76.

Going ahead to step 1:
76 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 76

Advancing to step 2:
The number 76 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 76

Let's proceed to step 3:
76 goes into 399 5 times with a remainder of 19.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 380 from 399 and we're left with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 76

On to step 4:
If we divide 194 by 76, we get 2 and a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 152 from 194 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 76

On to step 5:
When dividing 428 by 76, we get 5 with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 525.0
Deduct 380 from 428 and we're left with 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 76

Moving on to step 6:
If we divide 488 by 76, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5256.0
The remainder is 32 after subtracting 456 from 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
76 goes into 320 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 5256.4
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
76 can be fit into 160 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5256.42
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
76 can be fit into 80 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 5256.421
If we subtract 76 from 80, 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.

Let's proceed to step 10:
76 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5256.421
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
76 goes into 400 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 5256.42105
Subtract 380 from 400 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 76 fits into 200 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 5256.421052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
76 goes into 480 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 5256.4210526
Subtract 456 from 480 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.

Going ahead to step 14:
When dividing 240 by 76, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 5256.42105263
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 5256.42105263 and a remainder of 1.2e-08.
