We're dividing 66561716 by 307 
Let's see how many times 307 fits into 66561716.

Let's proceed to step 1:
If we divide 6 by 307, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 307

Going ahead to step 2:
The number 307 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 307

Going ahead to step 3:
If we divide 665 by 307, we get 2 and a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 614 from 665 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 307

On to step 4:
307 can be fit into 516 1 times, resulting in a remainder of 209.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 209 after subtracting 307 from 516.
Fetch the next digit (1) from the dividend, attach it to 209 and continue: 2091 / 307

On to step 5:
If we divide 2091 by 307, we get 6 and a remainder of 249.
Put 6 as the next digit of the answer. 
Result so far: 216.0
The remainder is 249 after subtracting 1842 from 2091.
Take the next digit (7) from the dividend and append it to 249, then repeat: 2497 / 307

Step 6:
307 can be fit into 2497 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 2168.0
Deduct 2456 from 2497 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 307

Let's proceed to step 7:
If we divide 411 by 307, we get 1 and a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 21681.0
If we take 307 away from 411, we end up with 104.
Append the next digit (6) from the dividend to 104 and continue with: 1046 / 307

Advancing to step 8:
307 goes into 1046 3 times with a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 216813.0
If we subtract 921 from 1046, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
The number 307 fits into 1250 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 216813.4
Subtract 1228 from 1250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
307 can be fit into 220 0 times, resulting in a remainder of 220.
The next digit of our result is 0. 
Result so far: 216813.4
If we subtract 0 from 220, 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.

Going ahead to step 11:
307 goes into 2200 7 times with a remainder of 51.
The next digit of our result is 7. 
Result so far: 216813.407
Subtract 2149 from 2200 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
307 goes into 510 1 times with a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 216813.4071
Subtracting 307 from 510 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 13:
The number 307 fits into 2030 6 times, leaving a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 216813.40716
If we take 1842 away from 2030, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 14:
The number 307 fits into 1880 6 times, leaving a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 216813.407166
If we subtract 1842 from 1880, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 216813.407166, with a leftover of 3.8e-06.
