We look at the division of 55026305 by 399 
We're looking to find how many times 399 goes into 55026305.

Let's proceed to step 1:
If we divide 5 by 399, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 399

Advancing to step 2:
399 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 399

Advancing to step 3:
399 can be fit into 550 1 times, resulting in a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 151 after subtracting 399 from 550.
Bring next digit (2) of the dividend behind the 151 and repeat the process: 1512 / 399

On to step 4:
1512 divided by 399 is 3 with a remainder of 315.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1197 from 1512 leaves us with 315.
Include the next digit (6) from the dividend after 315, then repeat: 3156 / 399

Step 5:
When dividing 3156 by 399, we get 7 with a remainder of 363.
The next digit of our result is 7. 
Result so far: 137.0
If we take 2793 away from 3156, we end up with 363.
Fetch the next digit (3) from the dividend, attach it to 363 and continue: 3633 / 399

Let's proceed to step 6:
3633 divided by 399 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 1379.0
Subtracting 3591 from 3633 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 399

Moving on to step 7:
399 can be fit into 420 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 13791.0
The remainder is 21 after subtracting 399 from 420.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 399

Moving on to step 8:
399 goes into 215 0 times with a remainder of 215.
The next digit of our result is 0. 
Result so far: 137910.0
Deduct 0 from 215 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
The number 399 fits into 2150 5 times, leaving a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 137910.5
Subtracting 1995 from 2150 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 10:
The number 399 fits into 1550 3 times, leaving a remainder of 353.
Put 3 as the next digit of the answer. 
Result so far: 137910.53
If we subtract 1197 from 1550, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 11:
The number 399 fits into 3530 8 times, leaving a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 137910.538
Subtract 3192 from 3530 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 12:
If we divide 3380 by 399, we get 8 and a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 137910.5388
If we take 3192 away from 3380, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 137910.5388 with a remaining 0.00188.
