We divide 64103145 by 66
We want to divide 64103145 by 66.

Going ahead to step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 66

On to step 2:
64 divided by 66 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 66

Advancing to step 3:
66 goes into 641 9 times with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 47 after subtracting 594 from 641.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 66

Advancing to step 4:
If we divide 470 by 66, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 462 from 470 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 66

Going ahead to step 5:
66 can be fit into 83 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 971.0
Deduct 66 from 83 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 66

Step 6:
When dividing 171 by 66, we get 2 with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 9712.0
Deduct 132 from 171 and we're left with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 66

Advancing to step 7:
394 divided by 66 is 5 with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 97125.0
The remainder is 64 after subtracting 330 from 394.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 66

Moving on to step 8:
When dividing 645 by 66, we get 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 971259.0
The remainder is 51 after subtracting 594 from 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
66 can be fit into 510 7 times, resulting in a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 971259.7
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 971259.77
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 971259.77 with a remaining 0.018.
