53109505 ÷ 10 
We're looking to find how many times 10 goes into 53109505.

Advancing to step 1:
10 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 10

Going ahead to step 2:
If we divide 53 by 10, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 50 from 53 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 10

Moving on to step 3:
When dividing 31 by 10, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 30 away from 31, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 10

Advancing to step 4:
If we divide 10 by 10, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 531.0
The remainder is 0 after subtracting 10 from 10.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 10

Step 5:
9 divided by 10 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 5310.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 10

Advancing to step 6:
If we divide 95 by 10, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 53109.0
Subtract 90 from 95 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 10

On to step 7:
10 can be fit into 50 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 531095.0
Deduct 50 from 50 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 10

Let's proceed to step 8:
When dividing 5 by 10, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 5310950.0
If we take 0 away from 5, we end up 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.

On to step 9:
If we divide 50 by 10, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5310950.5
If we take 50 away from 50, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5310950.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5310950.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 5310950.5 with a remainder of 0.0.
