637534 ÷ 77 
The aim is to understand the frequency of 77 in 637534.

Let's proceed to step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 77

Let's proceed to step 2:
77 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 77

Step 3:
77 goes into 637 8 times with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 616 from 637 leaves us with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 77

Let's proceed to step 4:
77 goes into 215 2 times with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 82.0
If we take 154 away from 215, we end up with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 77

Let's proceed to step 5:
When dividing 613 by 77, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 827.0
Subtract 539 from 613 to get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 77

On to step 6:
77 goes into 744 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 8279.0
Subtract 693 from 744 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
510 divided by 77 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 8279.6
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
77 goes into 480 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8279.66
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 8279.66, and the remainder is 0.018.
