We divide 45699591 by 312
We want to divide 45699591 by 312.

Step 1:
If we divide 4 by 312, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 312

Going ahead to step 2:
45 divided by 312 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 312

Moving on to step 3:
When dividing 456 by 312, we get 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 312 from 456, we get 144.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 312

Going ahead to step 4:
When dividing 1449 by 312, we get 4 with a remainder of 201.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1248 from 1449 and we're left with 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 312

Advancing to step 5:
312 can be fit into 2019 6 times, resulting in a remainder of 147.
The next digit of our result is 6. 
Result so far: 146.0
The remainder is 147 after subtracting 1872 from 2019.
Bring next digit (5) of the dividend behind the 147 and repeat the process: 1475 / 312

Moving on to step 6:
312 can be fit into 1475 4 times, resulting in a remainder of 227.
The number 4 becomes the next digit in our result. 
Result so far: 1464.0
If we subtract 1248 from 1475, we get 227.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 312

Moving on to step 7:
When dividing 2279 by 312, we get 7 with a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 14647.0
If we take 2184 away from 2279, we end up with 95.
Include the next digit (1) from the dividend after 95, then repeat: 951 / 312

Let's proceed to step 8:
951 divided by 312 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 146473.0
Subtract 936 from 951 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
312 goes into 150 0 times with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 146473.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
The number 312 fits into 1500 4 times, leaving a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 146473.04
Deduct 1248 from 1500 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
2520 divided by 312 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 146473.048
Deduct 2496 from 2520 and we're left 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 12:
312 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 146473.048
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
If we divide 2400 by 312, we get 7 and a remainder of 216.
The next digit of our result is 7. 
Result so far: 146473.04807
Deduct 2184 from 2400 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 14:
312 can be fit into 2160 6 times, resulting in a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 146473.048076
Subtract 1872 from 2160 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
2880 divided by 312 is 9 with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 146473.0480769
Subtracting 2808 from 2880 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
When dividing 720 by 312, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 146473.04807692
Subtracting 624 from 720 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 146473.04807692, and the remainder is 9.6e-08.
