Let's divide 1786611 by 506
The aim is to understand the frequency of 506 in 1786611.

Step 1:
506 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 506

Let's proceed to step 2:
When dividing 17 by 506, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 506

Going ahead to step 3:
The number 506 fits into 178 0 times, leaving a remainder of 178.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 178, we get 178.
Include the next digit (6) from the dividend after 178, then repeat: 1786 / 506

Let's proceed to step 4:
When dividing 1786 by 506, we get 3 with a remainder of 268.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1518 away from 1786, we end up with 268.
Include the next digit (6) from the dividend after 268, then repeat: 2686 / 506

On to step 5:
If we divide 2686 by 506, we get 5 and a remainder of 156.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 2530 from 2686 and we're left with 156.
Bring next digit (1) of the dividend behind the 156 and repeat the process: 1561 / 506

Step 6:
506 can be fit into 1561 3 times, resulting in a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 353.0
Subtracting 1518 from 1561 leaves us with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 506

Moving on to step 7:
506 can be fit into 431 0 times, resulting in a remainder of 431.
The next digit of our result is 0. 
Result so far: 3530.0
Deduct 0 from 431 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 8:
506 can be fit into 4310 8 times, resulting in a remainder of 262.
The next digit of our result is 8. 
Result so far: 3530.8
Subtracting 4048 from 4310 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 9:
506 goes into 2620 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 3530.85
If we take 2530 away from 2620, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
When dividing 900 by 506, we get 1 with a remainder of 394.
The next digit of our result is 1. 
Result so far: 3530.851
The remainder is 394 after subtracting 506 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 11:
3940 divided by 506 is 7 with a remainder of 398.
Use 7 as the next digit of our solution. 
Result so far: 3530.8517
Subtracting 3542 from 3940 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 12:
When dividing 3980 by 506, we get 7 with a remainder of 438.
Record the quotient 7 as the next digit in the result. 
Result so far: 3530.85177
The remainder is 438 after subtracting 3542 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final outcome is 3530.85177, with a leftover of 0.000438.
