We divide 97708399 by 771
The aim is to understand the frequency of 771 in 97708399.

On to step 1:
When dividing 9 by 771, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 771

Let's proceed to step 2:
When dividing 97 by 771, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 771

Let's proceed to step 3:
The number 771 fits into 977 1 times, leaving a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 771 away from 977, we end up with 206.
Include the next digit (0) from the dividend after 206, then repeat: 2060 / 771

Let's proceed to step 4:
When dividing 2060 by 771, we get 2 with a remainder of 518.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1542 from 2060 to get 518.
Append the next digit (8) from the dividend to 518 and continue with: 5188 / 771

On to step 5:
If we divide 5188 by 771, we get 6 and a remainder of 562.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 4626 from 5188 and we're left with 562.
Append the next digit (3) from the dividend to 562 and continue with: 5623 / 771

On to step 6:
771 goes into 5623 7 times with a remainder of 226.
Record the quotient 7 as the next digit in the result. 
Result so far: 1267.0
Subtracting 5397 from 5623 leaves us with 226.
Fetch the next digit (9) from the dividend, attach it to 226 and continue: 2269 / 771

Step 7:
The number 771 fits into 2269 2 times, leaving a remainder of 727.
Use 2 as the next digit of our solution. 
Result so far: 12672.0
Subtract 1542 from 2269 to get 727.
Fetch the next digit (9) from the dividend, attach it to 727 and continue: 7279 / 771

Advancing to step 8:
7279 divided by 771 is 9 with a remainder of 340.
Use 9 as the next digit of our solution. 
Result so far: 126729.0
Subtract 6939 from 7279 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
The number 771 fits into 3400 4 times, leaving a remainder of 316.
The next digit of our result is 4. 
Result so far: 126729.4
If we subtract 3084 from 3400, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
3160 divided by 771 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 126729.44
The remainder is 76 after subtracting 3084 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 126729.44, with a leftover of 0.076.
