55107580 divided by 839 
We're looking to find how many times 839 goes into 55107580.

Step 1:
839 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 839

Let's proceed to step 2:
839 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 839

Let's proceed to step 3:
839 goes into 551 0 times with a remainder of 551.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 551, we end up with 551.
Fetch the next digit (0) from the dividend, attach it to 551 and continue: 5510 / 839

Moving on to step 4:
839 goes into 5510 6 times with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 5034 from 5510 and we're left with 476.
Fetch the next digit (7) from the dividend, attach it to 476 and continue: 4767 / 839

Step 5:
839 goes into 4767 5 times with a remainder of 572.
The next digit of our result is 5. 
Result so far: 65.0
Subtracting 4195 from 4767 leaves us with 572.
Bring next digit (5) of the dividend behind the 572 and repeat the process: 5725 / 839

Step 6:
If we divide 5725 by 839, we get 6 and a remainder of 691.
Record the quotient 6 as the next digit in the result. 
Result so far: 656.0
If we take 5034 away from 5725, we end up with 691.
Take the next digit (8) from the dividend and append it to 691, then repeat: 6918 / 839

Step 7:
839 can be fit into 6918 8 times, resulting in a remainder of 206.
Put 8 as the next digit of the answer. 
Result so far: 6568.0
If we subtract 6712 from 6918, we get 206.
Fetch the next digit (0) from the dividend, attach it to 206 and continue: 2060 / 839

On to step 8:
2060 divided by 839 is 2 with a remainder of 382.
The next digit of our result is 2. 
Result so far: 65682.0
If we take 1678 away from 2060, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 9:
When dividing 3820 by 839, we get 4 with a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 65682.4
Deduct 3356 from 3820 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 10:
If we divide 4640 by 839, we get 5 and a remainder of 445.
The next digit of our result is 5. 
Result so far: 65682.45
If we take 4195 away from 4640, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 11:
The number 839 fits into 4450 5 times, leaving a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 65682.455
If we take 4195 away from 4450, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final outcome is 65682.455, with a leftover of 0.0255.
