Let's divide 54508809 by 315
We want to figure out the number of times 54508809 can be divided by 315.

Step 1:
If we divide 5 by 315, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 315

On to step 2:
54 divided by 315 is 0 with 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.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 315

Going ahead to step 3:
545 divided by 315 is 1 with a remainder of 230.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 315 from 545, we get 230.
Take the next digit (0) from the dividend and append it to 230, then repeat: 2300 / 315

Going ahead to step 4:
The number 315 fits into 2300 7 times, leaving a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 2205 from 2300 to get 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 315

Advancing to step 5:
The number 315 fits into 958 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtracting 945 from 958 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 315

Step 6:
When dividing 138 by 315, we get 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 1730.0
Deduct 0 from 138 and we're left with 138.
Include the next digit (0) from the dividend after 138, then repeat: 1380 / 315

Moving on to step 7:
315 can be fit into 1380 4 times, resulting in a remainder of 120.
The next digit of our result is 4. 
Result so far: 17304.0
If we subtract 1260 from 1380, we get 120.
Grab the next digit (9) from the dividend, add it to 120, then carry on: 1209 / 315

Step 8:
When dividing 1209 by 315, we get 3 with a remainder of 264.
The number 3 becomes the next digit in our result. 
Result so far: 173043.0
Subtracting 945 from 1209 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
If we divide 2640 by 315, we get 8 and a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 173043.8
If we take 2520 away from 2640, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
1200 divided by 315 is 3 with a remainder of 255.
Put 3 as the next digit of the answer. 
Result so far: 173043.83
Deduct 945 from 1200 and we're left 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.

Going ahead to step 11:
315 goes into 2550 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 173043.838
The remainder is 30 after subtracting 2520 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 315 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 173043.838
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 13:
When dividing 3000 by 315, we get 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 173043.83809
Subtracting 2835 from 3000 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
315 can be fit into 1650 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 173043.838095
The remainder is 75 after subtracting 1575 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
315 can be fit into 750 2 times, resulting in a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 173043.8380952
Deduct 630 from 750 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
When dividing 1200 by 315, we get 3 with a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 173043.83809523
Subtract 945 from 1200 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Our division results in 173043.83809523 with a remaining 2.55e-07.
