We're dividing 783130 by 77 
The aim is to understand the frequency of 77 in 783130.

Moving on to step 1:
7 divided by 77 is 0 with 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 77

Let's proceed to step 2:
If we divide 78 by 77, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 78 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 77

Advancing to step 3:
The number 77 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 77

Going ahead to step 4:
The number 77 fits into 131 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 77 from 131 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 77

Let's proceed to step 5:
77 goes into 543 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 1017.0
Subtracting 539 from 543 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 77

On to step 6:
When dividing 40 by 77, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10170.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
If we divide 400 by 77, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10170.5
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 77, we get 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 10170.51
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
77 goes into 730 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 10170.519
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 10170.5194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10170.51948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
77 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10170.51948
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10170.5194805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
77 goes into 150 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 10170.51948051
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 10170.51948051, and the remainder is 7.3e-08.
