We're dividing 75352169 by 648 
Our goal is to divide 75352169 by 648.

On to step 1:
648 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 648

Advancing to step 2:
75 divided by 648 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 648

Moving on to step 3:
If we divide 753 by 648, we get 1 and a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 648 from 753 leaves us with 105.
Append the next digit (5) from the dividend to 105 and continue with: 1055 / 648

Advancing to step 4:
648 goes into 1055 1 times with a remainder of 407.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 648 from 1055 to get 407.
Bring next digit (2) of the dividend behind the 407 and repeat the process: 4072 / 648

Step 5:
648 goes into 4072 6 times with a remainder of 184.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 3888 from 4072 and we're left with 184.
Append the next digit (1) from the dividend to 184 and continue with: 1841 / 648

Advancing to step 6:
1841 divided by 648 is 2 with a remainder of 545.
Write down 2 as next digit of the result. 
Result so far: 1162.0
Deduct 1296 from 1841 and we're left with 545.
Grab the next digit (6) from the dividend, add it to 545, then carry on: 5456 / 648

On to step 7:
The number 648 fits into 5456 8 times, leaving a remainder of 272.
The next digit of our result is 8. 
Result so far: 11628.0
Deduct 5184 from 5456 and we're left with 272.
Fetch the next digit (9) from the dividend, attach it to 272 and continue: 2729 / 648

Moving on to step 8:
648 goes into 2729 4 times with a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 116284.0
Subtracting 2592 from 2729 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
648 can be fit into 1370 2 times, resulting in a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 116284.2
The remainder is 74 after subtracting 1296 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 648, we get 1 and a remainder of 92.
The next digit of our result is 1. 
Result so far: 116284.21
Subtract 648 from 740 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
If we divide 920 by 648, we get 1 and a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 116284.211
If we take 648 away from 920, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 116284.211, with a leftover of 0.0272.
