78726664 ÷ 355 
Let's see how many times 355 fits into 78726664.

Step 1:
When dividing 7 by 355, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 355

Advancing to step 2:
355 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 355

Advancing to step 3:
If we divide 787 by 355, we get 2 and a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 710 from 787 and we're left with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 355

Let's proceed to step 4:
355 can be fit into 772 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 710 from 772, we get 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 355

Moving on to step 5:
626 divided by 355 is 1 with a remainder of 271.
The next digit of our result is 1. 
Result so far: 221.0
The remainder is 271 after subtracting 355 from 626.
Grab the next digit (6) from the dividend, add it to 271, then carry on: 2716 / 355

Advancing to step 6:
If we divide 2716 by 355, we get 7 and a remainder of 231.
Record the quotient 7 as the next digit in the result. 
Result so far: 2217.0
Subtracting 2485 from 2716 leaves us with 231.
Append the next digit (6) from the dividend to 231 and continue with: 2316 / 355

Advancing to step 7:
The number 355 fits into 2316 6 times, leaving a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 22176.0
Subtracting 2130 from 2316 leaves us with 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 355

Going ahead to step 8:
1864 divided by 355 is 5 with a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 221765.0
Subtracting 1775 from 1864 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
The number 355 fits into 890 2 times, leaving a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 221765.2
The remainder is 180 after subtracting 710 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
1800 divided by 355 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 221765.25
Subtracting 1775 from 1800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
355 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 221765.25
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
When dividing 2500 by 355, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 221765.2507
Subtracting 2485 from 2500 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
355 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 221765.2507
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
1500 divided by 355 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 221765.250704
If we subtract 1420 from 1500, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
355 can be fit into 800 2 times, resulting in a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 221765.2507042
If we take 710 away from 800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
When dividing 900 by 355, we get 2 with a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 221765.25070422
Subtract 710 from 900 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 221765.25070422 and a remainder of 1.9e-07.
