We're dividing 66209945 by 545 
We want to divide 66209945 by 545.

On to step 1:
545 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 545

Moving on to step 2:
The number 545 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 545

On to step 3:
662 divided by 545 is 1 with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 545 from 662 to get 117.
Include the next digit (0) from the dividend after 117, then repeat: 1170 / 545

Let's proceed to step 4:
545 can be fit into 1170 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1090 from 1170 leaves us with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 545

Let's proceed to step 5:
If we divide 809 by 545, we get 1 and a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Deduct 545 from 809 and we're left with 264.
Fetch the next digit (9) from the dividend, attach it to 264 and continue: 2649 / 545

Advancing to step 6:
545 goes into 2649 4 times with a remainder of 469.
Write down 4 as next digit of the result. 
Result so far: 1214.0
The remainder is 469 after subtracting 2180 from 2649.
Take the next digit (4) from the dividend and append it to 469, then repeat: 4694 / 545

Moving on to step 7:
4694 divided by 545 is 8 with a remainder of 334.
Write down 8 as next digit of the result. 
Result so far: 12148.0
If we subtract 4360 from 4694, we get 334.
Grab the next digit (5) from the dividend, add it to 334, then carry on: 3345 / 545

Moving on to step 8:
When dividing 3345 by 545, we get 6 with a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 121486.0
Deduct 3270 from 3345 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.

On to step 9:
545 goes into 750 1 times with a remainder of 205.
The next digit of our result is 1. 
Result so far: 121486.1
Subtract 545 from 750 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 10:
545 can be fit into 2050 3 times, resulting in a remainder of 415.
The next digit of our result is 3. 
Result so far: 121486.13
If we take 1635 away from 2050, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 11:
545 can be fit into 4150 7 times, resulting in a remainder of 335.
Record the quotient 7 as the next digit in the result. 
Result so far: 121486.137
Deduct 3815 from 4150 and we're left with 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 12:
The number 545 fits into 3350 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 121486.1376
Subtracting 3270 from 3350 leaves us 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 13:
When dividing 800 by 545, we get 1 with a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 121486.13761
Subtract 545 from 800 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 14:
545 can be fit into 2550 4 times, resulting in a remainder of 370.
The next digit of our result is 4. 
Result so far: 121486.137614
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.

On to step 15:
545 can be fit into 3700 6 times, resulting in a remainder of 430.
Record the quotient 6 as the next digit in the result. 
Result so far: 121486.1376146
Deduct 3270 from 3700 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 16:
545 goes into 4300 7 times with a remainder of 485.
Record the quotient 7 as the next digit in the result. 
Result so far: 121486.13761467
Subtract 3815 from 4300 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The quotient of the division is 121486.13761467, and the remainder is 4.85e-07.
