47218802 ÷ 405 
The aim is to understand the frequency of 405 in 47218802.

On to step 1:
405 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 405

Let's proceed to step 2:
405 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 405

Step 3:
The number 405 fits into 472 1 times, leaving a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 67 after subtracting 405 from 472.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 405

Moving on to step 4:
If we divide 671 by 405, we get 1 and a remainder of 266.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 405 from 671 leaves us with 266.
Include the next digit (8) from the dividend after 266, then repeat: 2668 / 405

Step 5:
If we divide 2668 by 405, we get 6 and a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 2430 away from 2668, we end up with 238.
Grab the next digit (8) from the dividend, add it to 238, then carry on: 2388 / 405

Advancing to step 6:
If we divide 2388 by 405, we get 5 and a remainder of 363.
The next digit of our result is 5. 
Result so far: 1165.0
Deduct 2025 from 2388 and we're left with 363.
Take the next digit (0) from the dividend and append it to 363, then repeat: 3630 / 405

Moving on to step 7:
405 goes into 3630 8 times with a remainder of 390.
Record the quotient 8 as the next digit in the result. 
Result so far: 11658.0
Subtracting 3240 from 3630 leaves us with 390.
Grab the next digit (2) from the dividend, add it to 390, then carry on: 3902 / 405

Let's proceed to step 8:
When dividing 3902 by 405, we get 9 with a remainder of 257.
The number 9 becomes the next digit in our result. 
Result so far: 116589.0
Deduct 3645 from 3902 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 9:
405 goes into 2570 6 times with a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 116589.6
Subtracting 2430 from 2570 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
405 can be fit into 1400 3 times, resulting in a remainder of 185.
The next digit of our result is 3. 
Result so far: 116589.63
Subtracting 1215 from 1400 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
The number 405 fits into 1850 4 times, leaving a remainder of 230.
The next digit of our result is 4. 
Result so far: 116589.634
Subtract 1620 from 1850 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 12:
When dividing 2300 by 405, we get 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 116589.6345
Subtracting 2025 from 2300 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 13:
405 can be fit into 2750 6 times, resulting in a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 116589.63456
If we subtract 2430 from 2750, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
If we divide 3200 by 405, we get 7 and a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 116589.634567
Subtracting 2835 from 3200 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 15:
If we divide 3650 by 405, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 116589.6345679
If we take 3645 away from 3650, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 16:
405 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 116589.6345679
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 116589.6345679, and the remainder is 5e-08.
