We look at the division of 70808274 by 486 
The aim is to understand the frequency of 486 in 70808274.

Going ahead to step 1:
When dividing 7 by 486, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 486

Going ahead to step 2:
70 divided by 486 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 486

Going ahead to step 3:
486 can be fit into 708 1 times, resulting in a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 486 from 708 leaves us with 222.
Bring next digit (0) of the dividend behind the 222 and repeat the process: 2220 / 486

Step 4:
486 goes into 2220 4 times with a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 1944 from 2220, we get 276.
Take the next digit (8) from the dividend and append it to 276, then repeat: 2768 / 486

Advancing to step 5:
486 can be fit into 2768 5 times, resulting in a remainder of 338.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 2430 away from 2768, we end up with 338.
Grab the next digit (2) from the dividend, add it to 338, then carry on: 3382 / 486

Going ahead to step 6:
3382 divided by 486 is 6 with a remainder of 466.
Put 6 as the next digit of the answer. 
Result so far: 1456.0
Deduct 2916 from 3382 and we're left with 466.
Include the next digit (7) from the dividend after 466, then repeat: 4667 / 486

Step 7:
The number 486 fits into 4667 9 times, leaving a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 14569.0
Deduct 4374 from 4667 and we're left with 293.
Bring next digit (4) of the dividend behind the 293 and repeat the process: 2934 / 486

Step 8:
When dividing 2934 by 486, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 145696.0
If we subtract 2916 from 2934, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
486 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 145696.0
Deduct 0 from 180 and we're left 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.

Going ahead to step 10:
486 goes into 1800 3 times with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 145696.03
Deduct 1458 from 1800 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 11:
When dividing 3420 by 486, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 145696.037
If we take 3402 away from 3420, 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 12:
The number 486 fits into 180 0 times, leaving a remainder of 180.
The next digit of our result is 0. 
Result so far: 145696.037
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
The number 486 fits into 1800 3 times, leaving a remainder of 342.
Record the quotient 3 as the next digit in the result. 
Result so far: 145696.03703
Deduct 1458 from 1800 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
When dividing 3420 by 486, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 145696.037037
The remainder is 18 after subtracting 3402 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
486 goes into 180 0 times with a remainder of 180.
The next digit of our result is 0. 
Result so far: 145696.037037
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
The number 486 fits into 1800 3 times, leaving a remainder of 342.
Put 3 as the next digit of the answer. 
Result so far: 145696.03703703
Deduct 1458 from 1800 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final result is 145696.03703703 with a remainder of 3.42e-07.
