We look at the division of 13566089 by 315 
We want to figure out the number of times 13566089 can be divided by 315.

Moving on to step 1:
1 divided by 315 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 315

On to step 2:
13 divided by 315 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 315

Advancing to step 3:
The number 315 fits into 135 0 times, leaving a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 135 and we're left with 135.
Bring next digit (6) of the dividend behind the 135 and repeat the process: 1356 / 315

On to step 4:
If we divide 1356 by 315, we get 4 and a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1260 from 1356 to get 96.
Take the next digit (6) from the dividend and append it to 96, then repeat: 966 / 315

Going ahead to step 5:
315 can be fit into 966 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 945 from 966 and we're left with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 315

Let's proceed to step 6:
When dividing 210 by 315, we get 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 430.0
Subtracting 0 from 210 leaves us with 210.
Include the next digit (8) from the dividend after 210, then repeat: 2108 / 315

Advancing to step 7:
If we divide 2108 by 315, we get 6 and a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 4306.0
Subtracting 1890 from 2108 leaves us with 218.
Fetch the next digit (9) from the dividend, attach it to 218 and continue: 2189 / 315

Moving on to step 8:
315 goes into 2189 6 times with a remainder of 299.
The number 6 becomes the next digit in our result. 
Result so far: 43066.0
Subtract 1890 from 2189 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
315 goes into 2990 9 times with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 43066.9
If we take 2835 away from 2990, we end up 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:
If we divide 1550 by 315, we get 4 and a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 43066.94
Deduct 1260 from 1550 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
2900 divided by 315 is 9 with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 43066.949
Subtracting 2835 from 2900 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
650 divided by 315 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 43066.9492
If we subtract 630 from 650, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
315 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 43066.9492
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
315 can be fit into 2000 6 times, resulting in a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 43066.949206
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
The number 315 fits into 1100 3 times, leaving a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 43066.9492063
If we subtract 945 from 1100, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 16:
1550 divided by 315 is 4 with a remainder of 290.
Use 4 as the next digit of our solution. 
Result so far: 43066.94920634
If we subtract 1260 from 1550, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 43066.94920634, with a leftover of 2.9e-07.
