Let's divide 45462873 by 312
We want to figure out the number of times 45462873 can be divided by 312.

Step 1:
312 can be fit into 4 0 times, resulting in 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 (5) from the dividend and append it to 4, then repeat: 45 / 312

Going ahead to step 2:
If we divide 45 by 312, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 312

Going ahead to step 3:
312 can be fit into 454 1 times, resulting in a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 312 away from 454, we end up with 142.
Include the next digit (6) from the dividend after 142, then repeat: 1426 / 312

Let's proceed to step 4:
1426 divided by 312 is 4 with a remainder of 178.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1248 from 1426 leaves us with 178.
Take the next digit (2) from the dividend and append it to 178, then repeat: 1782 / 312

Going ahead to step 5:
If we divide 1782 by 312, we get 5 and a remainder of 222.
Write down 5 as next digit of the result. 
Result so far: 145.0
The remainder is 222 after subtracting 1560 from 1782.
Grab the next digit (8) from the dividend, add it to 222, then carry on: 2228 / 312

Let's proceed to step 6:
312 goes into 2228 7 times with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 1457.0
Subtracting 2184 from 2228 leaves us with 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 312

Advancing to step 7:
The number 312 fits into 447 1 times, leaving a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 14571.0
Deduct 312 from 447 and we're left with 135.
Append the next digit (3) from the dividend to 135 and continue with: 1353 / 312

On to step 8:
The number 312 fits into 1353 4 times, leaving a remainder of 105.
Put 4 as the next digit of the answer. 
Result so far: 145714.0
Subtracting 1248 from 1353 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
312 can be fit into 1050 3 times, resulting in a remainder of 114.
The next digit of our result is 3. 
Result so far: 145714.3
Deduct 936 from 1050 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
312 can be fit into 1140 3 times, resulting in a remainder of 204.
Put 3 as the next digit of the answer. 
Result so far: 145714.33
Subtract 936 from 1140 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

In conclusion, the division gives 145714.33 with a balance of 0.204.
