We look at the division of 71210844 by 677 
The aim is to understand the frequency of 677 in 71210844.

Going ahead to step 1:
677 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 677

Step 2:
If we divide 71 by 677, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 677

Step 3:
When dividing 712 by 677, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 677 from 712 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 677

On to step 4:
If we divide 351 by 677, we get 0 and a remainder of 351.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 351 after subtracting 0 from 351.
Bring next digit (0) of the dividend behind the 351 and repeat the process: 3510 / 677

Going ahead to step 5:
If we divide 3510 by 677, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtracting 3385 from 3510 leaves us with 125.
Grab the next digit (8) from the dividend, add it to 125, then carry on: 1258 / 677

Step 6:
The number 677 fits into 1258 1 times, leaving a remainder of 581.
Use 1 as the next digit of our solution. 
Result so far: 1051.0
Subtract 677 from 1258 to get 581.
Append the next digit (4) from the dividend to 581 and continue with: 5814 / 677

Going ahead to step 7:
677 goes into 5814 8 times with a remainder of 398.
The number 8 becomes the next digit in our result. 
Result so far: 10518.0
Subtracting 5416 from 5814 leaves us with 398.
Append the next digit (4) from the dividend to 398 and continue with: 3984 / 677

Going ahead to step 8:
The number 677 fits into 3984 5 times, leaving a remainder of 599.
Record the quotient 5 as the next digit in the result. 
Result so far: 105185.0
Subtracting 3385 from 3984 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Advancing to step 9:
If we divide 5990 by 677, we get 8 and a remainder of 574.
Put 8 as the next digit of the answer. 
Result so far: 105185.8
Subtracting 5416 from 5990 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 10:
The number 677 fits into 5740 8 times, leaving a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 105185.88
If we subtract 5416 from 5740, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 105185.88 with a remainder of 0.324.
