55413863 ÷ 109 
Let's see how many times 109 fits into 55413863.

Moving on to step 1:
The number 109 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 109

On to step 2:
109 goes into 55 0 times with 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 (4) from the dividend, add it to 55, then carry on: 554 / 109

Let's proceed to step 3:
If we divide 554 by 109, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 545 away from 554, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 109

Advancing to step 4:
The number 109 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 109

Moving on to step 5:
109 goes into 913 8 times with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 508.0
If we take 872 away from 913, we end up with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 109

Moving on to step 6:
If we divide 418 by 109, we get 3 and a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 5083.0
If we take 327 away from 418, we end up with 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 109

Going ahead to step 7:
109 can be fit into 916 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 50838.0
The remainder is 44 after subtracting 872 from 916.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 109

On to step 8:
When dividing 443 by 109, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 508384.0
If we take 436 away from 443, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
When dividing 70 by 109, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 508384.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 109 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 508384.06
If we take 654 away from 700, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
The number 109 fits into 460 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 508384.064
The remainder is 24 after subtracting 436 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
109 can be fit into 240 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 508384.0642
The remainder is 22 after subtracting 218 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
When dividing 220 by 109, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 508384.06422
Subtract 218 from 220 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 508384.06422, with a leftover of 2e-06.
