We're dividing 66959310 by 305 
We want to divide 66959310 by 305.

Advancing to step 1:
The number 305 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 305

Moving on to step 2:
305 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 305

Advancing to step 3:
If we divide 669 by 305, we get 2 and a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 610 from 669 and we're left with 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 305

Let's proceed to step 4:
When dividing 595 by 305, we get 1 with a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 305 from 595, we get 290.
Grab the next digit (9) from the dividend, add it to 290, then carry on: 2909 / 305

Moving on to step 5:
The number 305 fits into 2909 9 times, leaving a remainder of 164.
Use 9 as the next digit of our solution. 
Result so far: 219.0
If we subtract 2745 from 2909, we get 164.
Append the next digit (3) from the dividend to 164 and continue with: 1643 / 305

Let's proceed to step 6:
If we divide 1643 by 305, we get 5 and a remainder of 118.
The number 5 becomes the next digit in our result. 
Result so far: 2195.0
Deduct 1525 from 1643 and we're left with 118.
Grab the next digit (1) from the dividend, add it to 118, then carry on: 1181 / 305

Advancing to step 7:
1181 divided by 305 is 3 with a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 21953.0
Subtract 915 from 1181 to get 266.
Bring next digit (0) of the dividend behind the 266 and repeat the process: 2660 / 305

Let's proceed to step 8:
The number 305 fits into 2660 8 times, leaving a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 219538.0
If we subtract 2440 from 2660, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 9:
2200 divided by 305 is 7 with a remainder of 65.
The next digit of our result is 7. 
Result so far: 219538.7
If we take 2135 away from 2200, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
650 divided by 305 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 219538.72
The remainder is 40 after subtracting 610 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 305 is 1 with a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 219538.721
The remainder is 95 after subtracting 305 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 12:
305 can be fit into 950 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 219538.7213
Deduct 915 from 950 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
If we divide 350 by 305, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 219538.72131
Deduct 305 from 350 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
If we divide 450 by 305, we get 1 and a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 219538.721311
Subtracting 305 from 450 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 219538.721311, with a leftover of 1.45e-05.
