We look at the division of 55100581 by 3 
Our goal is to divide 55100581 by 3.

On to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Let's proceed to step 2:
25 divided by 3 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 24 away from 25, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Going ahead to step 3:
When dividing 11 by 3, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
The remainder is 2 after subtracting 9 from 11.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Going ahead to step 4:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1836.0
Subtract 18 from 20 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Step 5:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 18366.0
Subtracting 18 from 20 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 183668.0
If we take 24 away from 25, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Step 7:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1836686.0
If we take 18 away from 18, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Going ahead to step 8:
1 divided by 3 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 18366860.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 18366860.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 18366860.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 18366860.33, with a leftover of 0.001.
