We divide 64596565 by 166
We want to divide 64596565 by 166.

Going ahead to step 1:
If we divide 6 by 166, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 166

Step 2:
When dividing 64 by 166, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 166

Going ahead to step 3:
The number 166 fits into 645 3 times, leaving a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 498 from 645, we get 147.
Grab the next digit (9) from the dividend, add it to 147, then carry on: 1479 / 166

On to step 4:
When dividing 1479 by 166, we get 8 with a remainder of 151.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 1328 from 1479 and we're left with 151.
Grab the next digit (6) from the dividend, add it to 151, then carry on: 1516 / 166

Let's proceed to step 5:
When dividing 1516 by 166, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 389.0
Subtract 1494 from 1516 to get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 166

Let's proceed to step 6:
225 divided by 166 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 3891.0
If we subtract 166 from 225, we get 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 166

Going ahead to step 7:
166 can be fit into 596 3 times, resulting in a remainder of 98.
The next digit of our result is 3. 
Result so far: 38913.0
If we take 498 away from 596, we end up with 98.
Include the next digit (5) from the dividend after 98, then repeat: 985 / 166

Moving on to step 8:
When dividing 985 by 166, we get 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 389135.0
The remainder is 155 after subtracting 830 from 985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
The number 166 fits into 1550 9 times, leaving a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 389135.9
Subtract 1494 from 1550 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 166, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 389135.93
Deduct 498 from 560 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
When dividing 620 by 166, we get 3 with a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 389135.933
Subtracting 498 from 620 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 389135.933 with a balance of 0.0122.
