We look at the division of 753746 by 77 
The aim is to understand the frequency of 77 in 753746.

Let's proceed to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 77

Moving on to step 2:
75 divided by 77 is 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 77

On to step 3:
77 can be fit into 753 9 times, resulting in a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 693 from 753 to get 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 77

Going ahead to step 4:
The number 77 fits into 607 7 times, leaving a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 539 away from 607, we end up with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 77

Let's proceed to step 5:
When dividing 684 by 77, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 978.0
Deduct 616 from 684 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 77

Going ahead to step 6:
If we divide 686 by 77, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 9788.0
The remainder is 70 after subtracting 616 from 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
700 divided by 77 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 9788.9
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 77 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 9788.9
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
77 goes into 700 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9788.909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
77 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9788.909
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 77, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 9788.90909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
70 divided by 77 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 9788.90909
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9788.9090909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 9788.9090909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 9788.9090909 and a remainder of 7e-08.
