Let's divide 45408607 by 312
We want to divide 45408607 by 312.

Advancing to step 1:
312 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
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 / 312

Let's proceed to step 2:
The number 312 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 312

Let's proceed to step 3:
The number 312 fits into 454 1 times, leaving a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 312 from 454, we get 142.
Include the next digit (0) from the dividend after 142, then repeat: 1420 / 312

Let's proceed to step 4:
312 goes into 1420 4 times with a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1248 from 1420 to get 172.
Fetch the next digit (8) from the dividend, attach it to 172 and continue: 1728 / 312

Advancing to step 5:
312 goes into 1728 5 times with a remainder of 168.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
If we take 1560 away from 1728, we end up with 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 312

Moving on to step 6:
312 can be fit into 1686 5 times, resulting in a remainder of 126.
Record the quotient 5 as the next digit in the result. 
Result so far: 1455.0
Subtract 1560 from 1686 to get 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 312

Going ahead to step 7:
312 can be fit into 1260 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 14554.0
Subtract 1248 from 1260 to get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 312

Going ahead to step 8:
When dividing 127 by 312, we get 0 with a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 145540.0
Subtract 0 from 127 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
312 goes into 1270 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 145540.4
If we take 1248 away from 1270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
312 can be fit into 220 0 times, resulting in a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 145540.4
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
When dividing 2200 by 312, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 145540.407
If we subtract 2184 from 2200, we 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.

Let's proceed to step 12:
312 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 145540.407
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
When dividing 1600 by 312, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 145540.40705
The remainder is 40 after subtracting 1560 from 1600.
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 14:
If we divide 400 by 312, we get 1 and a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 145540.407051
Subtract 312 from 400 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
If we divide 880 by 312, we get 2 and a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 145540.4070512
If we subtract 624 from 880, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
When dividing 2560 by 312, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 145540.40705128
Subtract 2496 from 2560 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 145540.40705128 with a balance of 6.4e-08.
