We're dividing 13506098 by 77 
The aim is to understand the frequency of 77 in 13506098.

On to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 77

Going ahead to step 2:
If we divide 13 by 77, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 77

Let's proceed to step 3:
When dividing 135 by 77, we get 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 77 from 135 and we're left with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 77

Going ahead to step 4:
The number 77 fits into 580 7 times, leaving a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 539 from 580 and we're left with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 77

Moving on to step 5:
If we divide 416 by 77, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 175.0
If we take 385 away from 416, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 77

Step 6:
If we divide 310 by 77, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 1754.0
The remainder is 2 after subtracting 308 from 310.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 77

Step 7:
The number 77 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 17540.0
The remainder is 29 after subtracting 0 from 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 77

Let's proceed to step 8:
77 goes into 298 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 175403.0
If we take 231 away from 298, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
The number 77 fits into 670 8 times, leaving a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 175403.8
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 175403.87
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
If we divide 10 by 77, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 175403.87
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
77 can be fit into 100 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 175403.8701
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
77 can be fit into 230 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 175403.87012
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
77 goes into 760 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 175403.870129
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 15:
77 goes into 670 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 175403.8701298
Subtract 616 from 670 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 16:
77 goes into 540 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 175403.87012987
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 175403.87012987, and the remainder is 1e-09.
