We look at the division of 83708277 by 798 
The aim is to understand the frequency of 798 in 83708277.

On to step 1:
If we divide 8 by 798, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 798

On to step 2:
798 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 798

Let's proceed to step 3:
The number 798 fits into 837 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 798 from 837 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 798

Going ahead to step 4:
798 can be fit into 390 0 times, resulting in a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 390 to get 390.
Append the next digit (8) from the dividend to 390 and continue with: 3908 / 798

On to step 5:
798 can be fit into 3908 4 times, resulting in a remainder of 716.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 3192 from 3908, we get 716.
Fetch the next digit (2) from the dividend, attach it to 716 and continue: 7162 / 798

On to step 6:
798 can be fit into 7162 8 times, resulting in a remainder of 778.
The number 8 becomes the next digit in our result. 
Result so far: 1048.0
Subtracting 6384 from 7162 leaves us with 778.
Include the next digit (7) from the dividend after 778, then repeat: 7787 / 798

Advancing to step 7:
798 can be fit into 7787 9 times, resulting in a remainder of 605.
The number 9 becomes the next digit in our result. 
Result so far: 10489.0
Subtracting 7182 from 7787 leaves us with 605.
Append the next digit (7) from the dividend to 605 and continue with: 6057 / 798

Going ahead to step 8:
When dividing 6057 by 798, we get 7 with a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 104897.0
Subtract 5586 from 6057 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 9:
The number 798 fits into 4710 5 times, leaving a remainder of 720.
The number 5 becomes the next digit in our result. 
Result so far: 104897.5
If we take 3990 away from 4710, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 10:
When dividing 7200 by 798, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 104897.59
If we take 7182 away from 7200, we end up 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.

Going ahead to step 11:
798 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 104897.59
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
The number 798 fits into 1800 2 times, leaving a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 104897.5902
Subtract 1596 from 1800 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
2040 divided by 798 is 2 with a remainder of 444.
The next digit of our result is 2. 
Result so far: 104897.59022
If we subtract 1596 from 2040, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Our division results in 104897.59022 with a remaining 0.000444.
