Let's divide 45579318 by 391
We're looking to find how many times 391 goes into 45579318.

On to step 1:
If we divide 4 by 391, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
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 / 391

Moving on to step 2:
391 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 391

Advancing to step 3:
If we divide 455 by 391, we get 1 and a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 64 after subtracting 391 from 455.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 391

Moving on to step 4:
391 goes into 647 1 times with a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 256 after subtracting 391 from 647.
Bring next digit (9) of the dividend behind the 256 and repeat the process: 2569 / 391

Going ahead to step 5:
If we divide 2569 by 391, we get 6 and a remainder of 223.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we take 2346 away from 2569, we end up with 223.
Fetch the next digit (3) from the dividend, attach it to 223 and continue: 2233 / 391

Going ahead to step 6:
2233 divided by 391 is 5 with a remainder of 278.
Write down 5 as next digit of the result. 
Result so far: 1165.0
Subtracting 1955 from 2233 leaves us with 278.
Include the next digit (1) from the dividend after 278, then repeat: 2781 / 391

Going ahead to step 7:
The number 391 fits into 2781 7 times, leaving a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 11657.0
If we subtract 2737 from 2781, we get 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 391

Advancing to step 8:
The number 391 fits into 448 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 116571.0
The remainder is 57 after subtracting 391 from 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
391 goes into 570 1 times with a remainder of 179.
The next digit of our result is 1. 
Result so far: 116571.1
If we take 391 away from 570, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 10:
391 goes into 1790 4 times with a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 116571.14
If we subtract 1564 from 1790, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 11:
391 can be fit into 2260 5 times, resulting in a remainder of 305.
The next digit of our result is 5. 
Result so far: 116571.145
If we take 1955 away from 2260, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 12:
3050 divided by 391 is 7 with a remainder of 313.
The next digit of our result is 7. 
Result so far: 116571.1457
If we take 2737 away from 3050, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 13:
391 can be fit into 3130 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 116571.14578
Subtracting 3128 from 3130 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
The number 391 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 116571.14578
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
391 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 116571.14578
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 116571.14578, with a leftover of 2e-06.
