Let's divide 66550305 by 545
We're looking to find how many times 545 goes into 66550305.

Moving on to step 1:
545 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 545

On to step 2:
The number 545 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 545

Step 3:
The number 545 fits into 665 1 times, leaving a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 545 from 665 leaves us with 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 545

Let's proceed to step 4:
1205 divided by 545 is 2 with a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1090 from 1205, we get 115.
Take the next digit (0) from the dividend and append it to 115, then repeat: 1150 / 545

Advancing to step 5:
545 goes into 1150 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 122.0
Subtracting 1090 from 1150 leaves us with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 545

Going ahead to step 6:
When dividing 603 by 545, we get 1 with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1221.0
Subtract 545 from 603 to get 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 545

Advancing to step 7:
The number 545 fits into 580 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 12211.0
Deduct 545 from 580 and we're left with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 545

Going ahead to step 8:
The number 545 fits into 355 0 times, leaving a remainder of 355.
The number 0 becomes the next digit in our result. 
Result so far: 122110.0
Subtract 0 from 355 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 9:
If we divide 3550 by 545, we get 6 and a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 122110.6
The remainder is 280 after subtracting 3270 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
545 goes into 2800 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 122110.65
Deduct 2725 from 2800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
If we divide 750 by 545, we get 1 and a remainder of 205.
The next digit of our result is 1. 
Result so far: 122110.651
If we take 545 away from 750, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 12:
The number 545 fits into 2050 3 times, leaving a remainder of 415.
Use 3 as the next digit of our solution. 
Result so far: 122110.6513
If we subtract 1635 from 2050, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 13:
The number 545 fits into 4150 7 times, leaving a remainder of 335.
Record the quotient 7 as the next digit in the result. 
Result so far: 122110.65137
If we subtract 3815 from 4150, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 14:
If we divide 3350 by 545, we get 6 and a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 122110.651376
If we take 3270 away from 3350, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
The number 545 fits into 800 1 times, leaving a remainder of 255.
Put 1 as the next digit of the answer. 
Result so far: 122110.6513761
The remainder is 255 after subtracting 545 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 16:
When dividing 2550 by 545, we get 4 with a remainder of 370.
The next digit of our result is 4. 
Result so far: 122110.65137614
Deduct 2180 from 2550 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

In conclusion, the division gives 122110.65137614 with a balance of 3.7e-07.
