45939372 ÷ 318 
We're looking to find how many times 318 goes into 45939372.

Let's proceed to step 1:
318 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 318

Let's proceed to step 2:
45 divided by 318 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 318

On to step 3:
318 can be fit into 459 1 times, resulting in a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 141 after subtracting 318 from 459.
Include the next digit (3) from the dividend after 141, then repeat: 1413 / 318

Let's proceed to step 4:
318 goes into 1413 4 times with a remainder of 141.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 141 after subtracting 1272 from 1413.
Fetch the next digit (9) from the dividend, attach it to 141 and continue: 1419 / 318

Advancing to step 5:
If we divide 1419 by 318, we get 4 and a remainder of 147.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 1272 from 1419 and we're left with 147.
Bring next digit (3) of the dividend behind the 147 and repeat the process: 1473 / 318

Going ahead to step 6:
The number 318 fits into 1473 4 times, leaving a remainder of 201.
The number 4 becomes the next digit in our result. 
Result so far: 1444.0
Subtract 1272 from 1473 to get 201.
Bring next digit (7) of the dividend behind the 201 and repeat the process: 2017 / 318

Step 7:
The number 318 fits into 2017 6 times, leaving a remainder of 109.
Record the quotient 6 as the next digit in the result. 
Result so far: 14446.0
Deduct 1908 from 2017 and we're left with 109.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 318

On to step 8:
If we divide 1092 by 318, we get 3 and a remainder of 138.
The next digit of our result is 3. 
Result so far: 144463.0
If we take 954 away from 1092, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
The number 318 fits into 1380 4 times, leaving a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 144463.4
If we take 1272 away from 1380, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
If we divide 1080 by 318, we get 3 and a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 144463.43
Deduct 954 from 1080 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
The number 318 fits into 1260 3 times, leaving a remainder of 306.
The next digit of our result is 3. 
Result so far: 144463.433
If we subtract 954 from 1260, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

In conclusion, the division gives 144463.433 with a balance of 0.0306.
