We look at the division of 74107159 by 648 
We're looking to find how many times 648 goes into 74107159.

Moving on to step 1:
If we divide 7 by 648, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 648

Advancing to step 2:
648 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 648

Step 3:
648 can be fit into 741 1 times, resulting in a remainder of 93.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 93 after subtracting 648 from 741.
Take the next digit (0) from the dividend and append it to 93, then repeat: 930 / 648

Step 4:
930 divided by 648 is 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 282 after subtracting 648 from 930.
Take the next digit (7) from the dividend and append it to 282, then repeat: 2827 / 648

Advancing to step 5:
648 can be fit into 2827 4 times, resulting in a remainder of 235.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 2592 from 2827 leaves us with 235.
Take the next digit (1) from the dividend and append it to 235, then repeat: 2351 / 648

Going ahead to step 6:
When dividing 2351 by 648, we get 3 with a remainder of 407.
Record the quotient 3 as the next digit in the result. 
Result so far: 1143.0
Deduct 1944 from 2351 and we're left with 407.
Grab the next digit (5) from the dividend, add it to 407, then carry on: 4075 / 648

On to step 7:
648 can be fit into 4075 6 times, resulting in a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 11436.0
Subtract 3888 from 4075 to get 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 648

Going ahead to step 8:
If we divide 1879 by 648, we get 2 and a remainder of 583.
The number 2 becomes the next digit in our result. 
Result so far: 114362.0
Subtract 1296 from 1879 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 9:
5830 divided by 648 is 8 with a remainder of 646.
Put 8 as the next digit of the answer. 
Result so far: 114362.8
If we take 5184 away from 5830, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Let's proceed to step 10:
The number 648 fits into 6460 9 times, leaving a remainder of 628.
Write down 9 as next digit of the result. 
Result so far: 114362.89
Subtract 5832 from 6460 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 11:
When dividing 6280 by 648, we get 9 with a remainder of 448.
Record the quotient 9 as the next digit in the result. 
Result so far: 114362.899
If we take 5832 away from 6280, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Our division results in 114362.899 with a remaining 0.0448.
