We're dividing 54973553 by 405 
We want to figure out the number of times 54973553 can be divided by 405.

Let's proceed to step 1:
405 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 405

Step 2:
If we divide 54 by 405, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 405

Advancing to step 3:
405 goes into 549 1 times with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 144 after subtracting 405 from 549.
Bring next digit (7) of the dividend behind the 144 and repeat the process: 1447 / 405

On to step 4:
1447 divided by 405 is 3 with a remainder of 232.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1215 from 1447, we get 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 405

Moving on to step 5:
If we divide 2323 by 405, we get 5 and a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 135.0
Deduct 2025 from 2323 and we're left with 298.
Include the next digit (5) from the dividend after 298, then repeat: 2985 / 405

Advancing to step 6:
When dividing 2985 by 405, we get 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 1357.0
If we take 2835 away from 2985, we end up with 150.
Grab the next digit (5) from the dividend, add it to 150, then carry on: 1505 / 405

Going ahead to step 7:
405 goes into 1505 3 times with a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 13573.0
If we take 1215 away from 1505, we end up with 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 405

Let's proceed to step 8:
When dividing 2903 by 405, we get 7 with a remainder of 68.
The next digit of our result is 7. 
Result so far: 135737.0
If we subtract 2835 from 2903, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
The number 405 fits into 680 1 times, leaving a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 135737.1
If we take 405 away from 680, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
If we divide 2750 by 405, we get 6 and a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 135737.16
The remainder is 320 after subtracting 2430 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
When dividing 3200 by 405, we get 7 with a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 135737.167
If we subtract 2835 from 3200, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 12:
3650 divided by 405 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 135737.1679
Subtracting 3645 from 3650 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
When dividing 50 by 405, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 135737.1679
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
405 can be fit into 500 1 times, resulting in a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 135737.167901
If we take 405 away from 500, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
405 can be fit into 950 2 times, resulting in a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 135737.1679012
Subtract 810 from 950 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
If we divide 1400 by 405, we get 3 and a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 135737.16790123
Deduct 1215 from 1400 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Our division results in 135737.16790123 with a remaining 1.85e-07.
