Let's divide 765772 by 771
The aim is to understand the frequency of 771 in 765772.

Step 1:
7 divided by 771 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 771

Step 2:
When dividing 76 by 771, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 771

Step 3:
If we divide 765 by 771, we get 0 and a remainder of 765.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 765 after subtracting 0 from 765.
Grab the next digit (7) from the dividend, add it to 765, then carry on: 7657 / 771

On to step 4:
When dividing 7657 by 771, we get 9 with a remainder of 718.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6939 from 7657 to get 718.
Grab the next digit (7) from the dividend, add it to 718, then carry on: 7187 / 771

On to step 5:
771 goes into 7187 9 times with a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 6939 from 7187 and we're left with 248.
Fetch the next digit (2) from the dividend, attach it to 248 and continue: 2482 / 771

Step 6:
771 goes into 2482 3 times with a remainder of 169.
The next digit of our result is 3. 
Result so far: 993.0
The remainder is 169 after subtracting 2313 from 2482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 7:
The number 771 fits into 1690 2 times, leaving a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 993.2
If we subtract 1542 from 1690, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 8:
771 can be fit into 1480 1 times, resulting in a remainder of 709.
The next digit of our result is 1. 
Result so far: 993.21
Deduct 771 from 1480 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Going ahead to step 9:
771 can be fit into 7090 9 times, resulting in a remainder of 151.
Use 9 as the next digit of our solution. 
Result so far: 993.219
Subtracting 6939 from 7090 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 10:
When dividing 1510 by 771, we get 1 with a remainder of 739.
Use 1 as the next digit of our solution. 
Result so far: 993.2191
If we take 771 away from 1510, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Let's proceed to step 11:
771 can be fit into 7390 9 times, resulting in a remainder of 451.
Put 9 as the next digit of the answer. 
Result so far: 993.21919
Deduct 6939 from 7390 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 12:
The number 771 fits into 4510 5 times, leaving a remainder of 655.
Use 5 as the next digit of our solution. 
Result so far: 993.219195
If we subtract 3855 from 4510, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Going ahead to step 13:
6550 divided by 771 is 8 with a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 993.2191958
If we subtract 6168 from 6550, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 14:
The number 771 fits into 3820 4 times, leaving a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 993.21919584
Subtracting 3084 from 3820 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final result is 993.21919584 with a remainder of 7.36e-07.
