We're dividing 66135955 by 566 
We want to divide 66135955 by 566.

Let's proceed to step 1:
566 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 566

Going ahead to step 2:
566 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 566

On to step 3:
When dividing 661 by 566, we get 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 566 from 661 and we're left with 95.
Append the next digit (3) from the dividend to 95 and continue with: 953 / 566

Step 4:
When dividing 953 by 566, we get 1 with a remainder of 387.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 566 from 953 leaves us with 387.
Bring next digit (5) of the dividend behind the 387 and repeat the process: 3875 / 566

Step 5:
566 can be fit into 3875 6 times, resulting in a remainder of 479.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 479 after subtracting 3396 from 3875.
Fetch the next digit (9) from the dividend, attach it to 479 and continue: 4799 / 566

Advancing to step 6:
4799 divided by 566 is 8 with a remainder of 271.
Use 8 as the next digit of our solution. 
Result so far: 1168.0
If we take 4528 away from 4799, we end up with 271.
Bring next digit (5) of the dividend behind the 271 and repeat the process: 2715 / 566

Advancing to step 7:
The number 566 fits into 2715 4 times, leaving a remainder of 451.
The number 4 becomes the next digit in our result. 
Result so far: 11684.0
Subtracting 2264 from 2715 leaves us with 451.
Grab the next digit (5) from the dividend, add it to 451, then carry on: 4515 / 566

Step 8:
When dividing 4515 by 566, we get 7 with a remainder of 553.
The number 7 becomes the next digit in our result. 
Result so far: 116847.0
If we take 3962 away from 4515, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Going ahead to step 9:
The number 566 fits into 5530 9 times, leaving a remainder of 436.
Record the quotient 9 as the next digit in the result. 
Result so far: 116847.9
If we take 5094 away from 5530, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 10:
If we divide 4360 by 566, we get 7 and a remainder of 398.
The next digit of our result is 7. 
Result so far: 116847.97
Subtract 3962 from 4360 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
3980 divided by 566 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 116847.977
Subtract 3962 from 3980 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 116847.977, with a leftover of 0.0018.
