We divide 45731331 by 391
Our goal is to divide 45731331 by 391.

Going ahead to step 1:
4 divided by 391 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 391

Moving on to step 2:
If we divide 45 by 391, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 391

Advancing to step 3:
391 goes into 457 1 times with a remainder of 66.
The next digit of our result is 1. 
Result so far: 1.0
If we take 391 away from 457, we end up with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 391

Moving on to step 4:
When dividing 663 by 391, we get 1 with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 391 from 663 and we're left with 272.
Grab the next digit (1) from the dividend, add it to 272, then carry on: 2721 / 391

Going ahead to step 5:
391 can be fit into 2721 6 times, resulting in a remainder of 375.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 375 after subtracting 2346 from 2721.
Include the next digit (3) from the dividend after 375, then repeat: 3753 / 391

Step 6:
When dividing 3753 by 391, we get 9 with a remainder of 234.
Write down 9 as next digit of the result. 
Result so far: 1169.0
If we subtract 3519 from 3753, we get 234.
Include the next digit (3) from the dividend after 234, then repeat: 2343 / 391

On to step 7:
2343 divided by 391 is 5 with a remainder of 388.
The number 5 becomes the next digit in our result. 
Result so far: 11695.0
The remainder is 388 after subtracting 1955 from 2343.
Take the next digit (1) from the dividend and append it to 388, then repeat: 3881 / 391

On to step 8:
3881 divided by 391 is 9 with a remainder of 362.
The next digit of our result is 9. 
Result so far: 116959.0
The remainder is 362 after subtracting 3519 from 3881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 9:
If we divide 3620 by 391, we get 9 and a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 116959.9
Subtract 3519 from 3620 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 10:
If we divide 1010 by 391, we get 2 and a remainder of 228.
The next digit of our result is 2. 
Result so far: 116959.92
The remainder is 228 after subtracting 782 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
If we divide 2280 by 391, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 116959.925
Subtracting 1955 from 2280 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 12:
391 can be fit into 3250 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 116959.9258
If we subtract 3128 from 3250, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 13:
The number 391 fits into 1220 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 116959.92583
If we take 1173 away from 1220, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
When dividing 470 by 391, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 116959.925831
The remainder is 79 after subtracting 391 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 15:
790 divided by 391 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 116959.9258312
Subtracting 782 from 790 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
391 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 116959.9258312
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 116959.9258312, and the remainder is 8e-08.
