We look at the division of 53505444 by 391 
We're looking to find how many times 391 goes into 53505444.

Moving on to step 1:
When dividing 5 by 391, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 391

Step 2:
The number 391 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 391

Advancing to step 3:
The number 391 fits into 535 1 times, leaving a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 391 from 535, we get 144.
Fetch the next digit (0) from the dividend, attach it to 144 and continue: 1440 / 391

Step 4:
1440 divided by 391 is 3 with a remainder of 267.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1173 from 1440 to get 267.
Take the next digit (5) from the dividend and append it to 267, then repeat: 2675 / 391

Step 5:
391 can be fit into 2675 6 times, resulting in a remainder of 329.
Use 6 as the next digit of our solution. 
Result so far: 136.0
If we subtract 2346 from 2675, we get 329.
Bring next digit (4) of the dividend behind the 329 and repeat the process: 3294 / 391

Let's proceed to step 6:
391 can be fit into 3294 8 times, resulting in a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Deduct 3128 from 3294 and we're left with 166.
Take the next digit (4) from the dividend and append it to 166, then repeat: 1664 / 391

Moving on to step 7:
391 goes into 1664 4 times with a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 13684.0
The remainder is 100 after subtracting 1564 from 1664.
Include the next digit (4) from the dividend after 100, then repeat: 1004 / 391

Step 8:
1004 divided by 391 is 2 with a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 136842.0
If we take 782 away from 1004, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
391 goes into 2220 5 times with a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 136842.5
Subtracting 1955 from 2220 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
When dividing 2650 by 391, we get 6 with a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 136842.56
If we subtract 2346 from 2650, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 11:
391 can be fit into 3040 7 times, resulting in a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 136842.567
Subtracting 2737 from 3040 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 12:
391 can be fit into 3030 7 times, resulting in a remainder of 293.
The number 7 becomes the next digit in our result. 
Result so far: 136842.5677
Deduct 2737 from 3030 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final result is 136842.5677 with a remainder of 0.00293.
