We're dividing 70448163 by 771 
The aim is to understand the frequency of 771 in 70448163.

Step 1:
If we divide 7 by 771, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 771

Step 2:
771 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 771

Advancing to step 3:
When dividing 704 by 771, we get 0 with a remainder of 704.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 704 to get 704.
Include the next digit (4) from the dividend after 704, then repeat: 7044 / 771

Moving on to step 4:
The number 771 fits into 7044 9 times, leaving a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 6939 from 7044 to get 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 771

Moving on to step 5:
When dividing 1058 by 771, we get 1 with a remainder of 287.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 771 from 1058 and we're left with 287.
Append the next digit (1) from the dividend to 287 and continue with: 2871 / 771

Moving on to step 6:
The number 771 fits into 2871 3 times, leaving a remainder of 558.
The next digit of our result is 3. 
Result so far: 913.0
Subtract 2313 from 2871 to get 558.
Include the next digit (6) from the dividend after 558, then repeat: 5586 / 771

Let's proceed to step 7:
When dividing 5586 by 771, we get 7 with a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 9137.0
If we take 5397 away from 5586, we end up with 189.
Bring next digit (3) of the dividend behind the 189 and repeat the process: 1893 / 771

Advancing to step 8:
771 can be fit into 1893 2 times, resulting in a remainder of 351.
Use 2 as the next digit of our solution. 
Result so far: 91372.0
If we take 1542 away from 1893, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
771 goes into 3510 4 times with a remainder of 426.
Put 4 as the next digit of the answer. 
Result so far: 91372.4
If we take 3084 away from 3510, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 10:
4260 divided by 771 is 5 with a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 91372.45
If we subtract 3855 from 4260, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 11:
The number 771 fits into 4050 5 times, leaving a remainder of 195.
The next digit of our result is 5. 
Result so far: 91372.455
Deduct 3855 from 4050 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The quotient of the division is 91372.455, and the remainder is 0.0195.
