13866160 ÷ 471 
The aim is to understand the frequency of 471 in 13866160.

Step 1:
When dividing 1 by 471, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 471

Let's proceed to step 2:
The number 471 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 471

Advancing to step 3:
When dividing 138 by 471, we get 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Append the next digit (6) from the dividend to 138 and continue with: 1386 / 471

Moving on to step 4:
471 can be fit into 1386 2 times, resulting in a remainder of 444.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 942 from 1386 and we're left with 444.
Fetch the next digit (6) from the dividend, attach it to 444 and continue: 4446 / 471

Going ahead to step 5:
471 can be fit into 4446 9 times, resulting in a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 4239 from 4446, we get 207.
Fetch the next digit (1) from the dividend, attach it to 207 and continue: 2071 / 471

Advancing to step 6:
When dividing 2071 by 471, we get 4 with a remainder of 187.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
If we subtract 1884 from 2071, we get 187.
Append the next digit (6) from the dividend to 187 and continue with: 1876 / 471

Going ahead to step 7:
471 goes into 1876 3 times with a remainder of 463.
Put 3 as the next digit of the answer. 
Result so far: 2943.0
If we take 1413 away from 1876, we end up with 463.
Fetch the next digit (0) from the dividend, attach it to 463 and continue: 4630 / 471

On to step 8:
When dividing 4630 by 471, we get 9 with a remainder of 391.
The number 9 becomes the next digit in our result. 
Result so far: 29439.0
If we subtract 4239 from 4630, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Moving on to step 9:
The number 471 fits into 3910 8 times, leaving a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 29439.8
Subtracting 3768 from 3910 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
If we divide 1420 by 471, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 29439.83
Subtract 1413 from 1420 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
471 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 29439.83
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
471 can be fit into 700 1 times, resulting in a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 29439.8301
Deduct 471 from 700 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 13:
471 can be fit into 2290 4 times, resulting in a remainder of 406.
Use 4 as the next digit of our solution. 
Result so far: 29439.83014
If we take 1884 away from 2290, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 14:
471 can be fit into 4060 8 times, resulting in a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 29439.830148
Subtract 3768 from 4060 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 15:
471 can be fit into 2920 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 29439.8301486
If we take 2826 away from 2920, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 16:
471 goes into 940 1 times with a remainder of 469.
Record the quotient 1 as the next digit in the result. 
Result so far: 29439.83014861
Deduct 471 from 940 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

After the division, we end up with 29439.83014861 and a remainder of 4.69e-07.
