We divide 66244715 by 321
We're looking to find how many times 321 goes into 66244715.

Step 1:
6 divided by 321 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 321

Going ahead to step 2:
321 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 321

On to step 3:
662 divided by 321 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 642 from 662 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 321

Step 4:
204 divided by 321 is 0 with a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 204 and we're left with 204.
Take the next digit (4) from the dividend and append it to 204, then repeat: 2044 / 321

Let's proceed to step 5:
321 can be fit into 2044 6 times, resulting in a remainder of 118.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtracting 1926 from 2044 leaves us with 118.
Take the next digit (7) from the dividend and append it to 118, then repeat: 1187 / 321

Let's proceed to step 6:
1187 divided by 321 is 3 with a remainder of 224.
Record the quotient 3 as the next digit in the result. 
Result so far: 2063.0
Subtract 963 from 1187 to get 224.
Grab the next digit (1) from the dividend, add it to 224, then carry on: 2241 / 321

Advancing to step 7:
When dividing 2241 by 321, we get 6 with a remainder of 315.
The next digit of our result is 6. 
Result so far: 20636.0
If we take 1926 away from 2241, we end up with 315.
Include the next digit (5) from the dividend after 315, then repeat: 3155 / 321

Moving on to step 8:
If we divide 3155 by 321, we get 9 and a remainder of 266.
The number 9 becomes the next digit in our result. 
Result so far: 206369.0
Subtract 2889 from 3155 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 9:
2660 divided by 321 is 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 206369.8
Subtract 2568 from 2660 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
920 divided by 321 is 2 with a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 206369.82
Deduct 642 from 920 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 11:
321 can be fit into 2780 8 times, resulting in a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 206369.828
Deduct 2568 from 2780 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 12:
If we divide 2120 by 321, we get 6 and a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 206369.8286
Subtracting 1926 from 2120 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 13:
When dividing 1940 by 321, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 206369.82866
Subtract 1926 from 1940 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 206369.82866, with a leftover of 1.4e-05.
