Let's divide 19912211 by 486
The aim is to understand the frequency of 486 in 19912211.

Going ahead to step 1:
If we divide 1 by 486, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 486

On to step 2:
When dividing 19 by 486, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 486

Moving on to step 3:
199 divided by 486 is 0 with a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 199 leaves us with 199.
Grab the next digit (1) from the dividend, add it to 199, then carry on: 1991 / 486

On to step 4:
If we divide 1991 by 486, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1944 from 1991 leaves us with 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 486

Let's proceed to step 5:
486 can be fit into 472 0 times, resulting in a remainder of 472.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 472, we get 472.
Append the next digit (2) from the dividend to 472 and continue with: 4722 / 486

On to step 6:
The number 486 fits into 4722 9 times, leaving a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 409.0
Subtract 4374 from 4722 to get 348.
Bring next digit (1) of the dividend behind the 348 and repeat the process: 3481 / 486

Going ahead to step 7:
The number 486 fits into 3481 7 times, leaving a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 4097.0
Subtract 3402 from 3481 to get 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 486

Step 8:
The number 486 fits into 791 1 times, leaving a remainder of 305.
The next digit of our result is 1. 
Result so far: 40971.0
The remainder is 305 after subtracting 486 from 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
3050 divided by 486 is 6 with a remainder of 134.
The next digit of our result is 6. 
Result so far: 40971.6
If we subtract 2916 from 3050, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
If we divide 1340 by 486, we get 2 and a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 40971.62
If we take 972 away from 1340, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
The number 486 fits into 3680 7 times, leaving a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 40971.627
Subtract 3402 from 3680 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 12:
The number 486 fits into 2780 5 times, leaving a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 40971.6275
Subtract 2430 from 2780 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
If we divide 3500 by 486, we get 7 and a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 40971.62757
Subtracting 3402 from 3500 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 14:
When dividing 980 by 486, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 40971.627572
If we take 972 away from 980, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
80 divided by 486 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 40971.627572
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
486 can be fit into 800 1 times, resulting in a remainder of 314.
The next digit of our result is 1. 
Result so far: 40971.62757201
If we take 486 away from 800, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

After the division, we end up with 40971.62757201 and a remainder of 3.14e-07.
