We're dividing 8213002 by 771 
The aim is to understand the frequency of 771 in 8213002.

Moving on to step 1:
771 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 771

On to step 2:
771 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 771

Step 3:
771 goes into 821 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 771 from 821 and we're left with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 771

Moving on to step 4:
771 can be fit into 503 0 times, resulting in a remainder of 503.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 503, we end up with 503.
Grab the next digit (0) from the dividend, add it to 503, then carry on: 5030 / 771

On to step 5:
If we divide 5030 by 771, we get 6 and a remainder of 404.
The next digit of our result is 6. 
Result so far: 106.0
The remainder is 404 after subtracting 4626 from 5030.
Append the next digit (0) from the dividend to 404 and continue with: 4040 / 771

Advancing to step 6:
771 goes into 4040 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 1065.0
Subtract 3855 from 4040 to get 185.
Fetch the next digit (2) from the dividend, attach it to 185 and continue: 1852 / 771

Advancing to step 7:
771 goes into 1852 2 times with a remainder of 310.
Put 2 as the next digit of the answer. 
Result so far: 10652.0
Deduct 1542 from 1852 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 8:
771 goes into 3100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10652.4
If we subtract 3084 from 3100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 771 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 10652.4
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 771 is 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 10652.402
The remainder is 58 after subtracting 1542 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
If we divide 580 by 771, we get 0 and a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 10652.402
Subtract 0 from 580 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 12:
771 can be fit into 5800 7 times, resulting in a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 10652.40207
Deduct 5397 from 5800 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 13:
When dividing 4030 by 771, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 10652.402075
Subtract 3855 from 4030 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 14:
When dividing 1750 by 771, we get 2 with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 10652.4020752
If we subtract 1542 from 1750, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
If we divide 2080 by 771, we get 2 and a remainder of 538.
The number 2 becomes the next digit in our result. 
Result so far: 10652.40207522
Deduct 1542 from 2080 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

After the division, we end up with 10652.40207522 and a remainder of 5.38e-07.
