We're dividing 31223051 by 487 
The aim is to understand the frequency of 487 in 31223051.

Advancing to step 1:
3 divided by 487 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 487

Going ahead to step 2:
When dividing 31 by 487, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 487

Let's proceed to step 3:
312 divided by 487 is 0 with a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 312, we get 312.
Append the next digit (2) from the dividend to 312 and continue with: 3122 / 487

Advancing to step 4:
The number 487 fits into 3122 6 times, leaving a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 2922 away from 3122, we end up with 200.
Bring next digit (3) of the dividend behind the 200 and repeat the process: 2003 / 487

Advancing to step 5:
If we divide 2003 by 487, we get 4 and a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 1948 from 2003 leaves us with 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 487

Step 6:
When dividing 550 by 487, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 641.0
If we subtract 487 from 550, we get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 487

Moving on to step 7:
The number 487 fits into 635 1 times, leaving a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 6411.0
The remainder is 148 after subtracting 487 from 635.
Fetch the next digit (1) from the dividend, attach it to 148 and continue: 1481 / 487

Going ahead to step 8:
When dividing 1481 by 487, we get 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 64113.0
Subtract 1461 from 1481 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
487 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 64113.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
The number 487 fits into 2000 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 64113.04
The remainder is 52 after subtracting 1948 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
487 goes into 520 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 64113.041
Subtract 487 from 520 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
If we divide 330 by 487, we get 0 and a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 64113.041
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
487 can be fit into 3300 6 times, resulting in a remainder of 378.
Record the quotient 6 as the next digit in the result. 
Result so far: 64113.04106
If we subtract 2922 from 3300, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 14:
3780 divided by 487 is 7 with a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 64113.041067
If we take 3409 away from 3780, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 15:
The number 487 fits into 3710 7 times, leaving a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 64113.0410677
Subtract 3409 from 3710 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final outcome is 64113.0410677, with a leftover of 3.01e-06.
