We're dividing 53145174 by 886 
Let's see how many times 886 fits into 53145174.

Going ahead to step 1:
886 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 886

Going ahead to step 2:
53 divided by 886 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 886

On to step 3:
When dividing 531 by 886, we get 0 with a remainder of 531.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 531 leaves us with 531.
Take the next digit (4) from the dividend and append it to 531, then repeat: 5314 / 886

Let's proceed to step 4:
The number 886 fits into 5314 5 times, leaving a remainder of 884.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4430 away from 5314, we end up with 884.
Include the next digit (5) from the dividend after 884, then repeat: 8845 / 886

Going ahead to step 5:
If we divide 8845 by 886, we get 9 and a remainder of 871.
Write down 9 as next digit of the result. 
Result so far: 59.0
The remainder is 871 after subtracting 7974 from 8845.
Bring next digit (1) of the dividend behind the 871 and repeat the process: 8711 / 886

Advancing to step 6:
The number 886 fits into 8711 9 times, leaving a remainder of 737.
Put 9 as the next digit of the answer. 
Result so far: 599.0
Subtracting 7974 from 8711 leaves us with 737.
Append the next digit (7) from the dividend to 737 and continue with: 7377 / 886

Going ahead to step 7:
7377 divided by 886 is 8 with a remainder of 289.
The number 8 becomes the next digit in our result. 
Result so far: 5998.0
Subtracting 7088 from 7377 leaves us with 289.
Append the next digit (4) from the dividend to 289 and continue with: 2894 / 886

Moving on to step 8:
If we divide 2894 by 886, we get 3 and a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 59983.0
Subtract 2658 from 2894 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
When dividing 2360 by 886, we get 2 with a remainder of 588.
The number 2 becomes the next digit in our result. 
Result so far: 59983.2
The remainder is 588 after subtracting 1772 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 10:
886 can be fit into 5880 6 times, resulting in a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 59983.26
Deduct 5316 from 5880 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 11:
If we divide 5640 by 886, we get 6 and a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 59983.266
If we subtract 5316 from 5640, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 59983.266, with a leftover of 0.0324.
