We divide 66573800 by 772
The aim is to understand the frequency of 772 in 66573800.

On to step 1:
772 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 772

Going ahead to step 2:
The number 772 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 772

Step 3:
772 goes into 665 0 times with a remainder of 665.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 665 to get 665.
Grab the next digit (7) from the dividend, add it to 665, then carry on: 6657 / 772

On to step 4:
When dividing 6657 by 772, we get 8 with a remainder of 481.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 481 after subtracting 6176 from 6657.
Bring next digit (3) of the dividend behind the 481 and repeat the process: 4813 / 772

Going ahead to step 5:
When dividing 4813 by 772, we get 6 with a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 4632 from 4813 to get 181.
Bring next digit (8) of the dividend behind the 181 and repeat the process: 1818 / 772

Step 6:
772 can be fit into 1818 2 times, resulting in a remainder of 274.
The next digit of our result is 2. 
Result so far: 862.0
Subtract 1544 from 1818 to get 274.
Fetch the next digit (0) from the dividend, attach it to 274 and continue: 2740 / 772

Moving on to step 7:
772 can be fit into 2740 3 times, resulting in a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 8623.0
The remainder is 424 after subtracting 2316 from 2740.
Grab the next digit (0) from the dividend, add it to 424, then carry on: 4240 / 772

Let's proceed to step 8:
If we divide 4240 by 772, we get 5 and a remainder of 380.
The next digit of our result is 5. 
Result so far: 86235.0
If we take 3860 away from 4240, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
772 can be fit into 3800 4 times, resulting in a remainder of 712.
The next digit of our result is 4. 
Result so far: 86235.4
If we take 3088 away from 3800, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 10:
7120 divided by 772 is 9 with a remainder of 172.
The next digit of our result is 9. 
Result so far: 86235.49
If we subtract 6948 from 7120, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
The number 772 fits into 1720 2 times, leaving a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 86235.492
If we subtract 1544 from 1720, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
772 goes into 1760 2 times with a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 86235.4922
Subtract 1544 from 1760 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 86235.4922, and the remainder is 0.00216.
