We look at the division of 12979148 by 771 
The aim is to understand the frequency of 771 in 12979148.

Let's proceed to step 1:
1 divided by 771 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 771

Let's proceed to step 2:
12 divided by 771 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 771

Step 3:
771 can be fit into 129 0 times, resulting in a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 771

Advancing to step 4:
If we divide 1297 by 771, we get 1 and a remainder of 526.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 771 away from 1297, we end up with 526.
Bring next digit (9) of the dividend behind the 526 and repeat the process: 5269 / 771

Moving on to step 5:
771 goes into 5269 6 times with a remainder of 643.
The next digit of our result is 6. 
Result so far: 16.0
If we take 4626 away from 5269, we end up with 643.
Take the next digit (1) from the dividend and append it to 643, then repeat: 6431 / 771

Step 6:
When dividing 6431 by 771, we get 8 with a remainder of 263.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Subtract 6168 from 6431 to get 263.
Fetch the next digit (4) from the dividend, attach it to 263 and continue: 2634 / 771

On to step 7:
2634 divided by 771 is 3 with a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 1683.0
If we subtract 2313 from 2634, we get 321.
Include the next digit (8) from the dividend after 321, then repeat: 3218 / 771

Going ahead to step 8:
771 goes into 3218 4 times with a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 16834.0
Subtract 3084 from 3218 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
If we divide 1340 by 771, we get 1 and a remainder of 569.
The next digit of our result is 1. 
Result so far: 16834.1
If we take 771 away from 1340, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 10:
The number 771 fits into 5690 7 times, leaving a remainder of 293.
The number 7 becomes the next digit in our result. 
Result so far: 16834.17
Deduct 5397 from 5690 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 11:
When dividing 2930 by 771, we get 3 with a remainder of 617.
Put 3 as the next digit of the answer. 
Result so far: 16834.173
Subtracting 2313 from 2930 leaves us with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 12:
If we divide 6170 by 771, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 16834.1738
If we take 6168 away from 6170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 771, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16834.1738
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 771, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 16834.1738
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 16834.1738 and a remainder of 2e-05.
