785537 ÷ 77 
The aim is to understand the frequency of 77 in 785537.

Step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 77

Let's proceed to step 2:
77 can be fit into 78 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 78 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 77

Advancing to step 3:
If we divide 15 by 77, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 77

Advancing to step 4:
When dividing 155 by 77, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 1 after subtracting 154 from 155.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 77

Moving on to step 5:
When dividing 13 by 77, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 1020.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 77

Advancing to step 6:
77 goes into 137 1 times with a remainder of 60.
The next digit of our result is 1. 
Result so far: 10201.0
Deduct 77 from 137 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 77 fits into 600 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 10201.7
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
When dividing 610 by 77, we get 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 10201.77
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 10201.77, with a leftover of 0.071.
