315321 ÷ 76 
Let's see how many times 76 fits into 315321.

Advancing to step 1:
When dividing 3 by 76, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 76

Advancing to step 2:
The number 76 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 76

Advancing to step 3:
76 can be fit into 315 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 304 from 315 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 76

On to step 4:
The number 76 fits into 113 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 76 from 113 and we're left with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 76

Moving on to step 5:
The number 76 fits into 372 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
The remainder is 68 after subtracting 304 from 372.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 76

Step 6:
The number 76 fits into 681 8 times, leaving a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 4148.0
Subtracting 608 from 681 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
730 divided by 76 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 4148.9
Subtracting 684 from 730 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
460 divided by 76 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4148.96
Subtracting 456 from 460 leaves us with 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:
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: 4148.96
Deduct 0 from 40 and we're left 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.

On to step 10:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4148.9605
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 11:
The number 76 fits into 200 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 4148.96052
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.

Let's proceed to step 12:
480 divided by 76 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4148.960526
Subtracting 456 from 480 leaves us 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.

Let's proceed to step 13:
When dividing 240 by 76, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 4148.9605263
If we take 228 away from 240, we end up 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.

Step 14:
When dividing 120 by 76, we get 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 4148.96052631
Subtracting 76 from 120 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 4148.96052631, with a leftover of 4.4e-08.
