Let's divide 561053 by 15
We're looking to find how many times 15 goes into 561053.

Advancing to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 15

On to step 2:
If we divide 56 by 15, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 45 from 56 and we're left with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 15

Advancing to step 3:
When dividing 111 by 15, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 105 from 111 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Step 4:
When dividing 60 by 15, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 374.0
Deduct 60 from 60 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

On to step 5:
5 divided by 15 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 3740.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 15

Moving on to step 6:
15 can be fit into 53 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 37403.0
The remainder is 8 after subtracting 45 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 37403.5
Subtract 75 from 80 to get 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 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 37403.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 37403.533
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 37403.533, with a leftover of 0.0005.
