15631669 ÷ 470 
The aim is to understand the frequency of 470 in 15631669.

Step 1:
The number 470 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 470

Going ahead to step 2:
15 divided by 470 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 470

On to step 3:
The number 470 fits into 156 0 times, leaving a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 470

Step 4:
The number 470 fits into 1563 3 times, leaving a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1410 from 1563 to get 153.
Fetch the next digit (1) from the dividend, attach it to 153 and continue: 1531 / 470

Advancing to step 5:
The number 470 fits into 1531 3 times, leaving a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 1410 away from 1531, we end up with 121.
Bring next digit (6) of the dividend behind the 121 and repeat the process: 1216 / 470

Advancing to step 6:
When dividing 1216 by 470, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
Deduct 940 from 1216 and we're left with 276.
Include the next digit (6) from the dividend after 276, then repeat: 2766 / 470

Going ahead to step 7:
470 can be fit into 2766 5 times, resulting in a remainder of 416.
Put 5 as the next digit of the answer. 
Result so far: 3325.0
If we subtract 2350 from 2766, we get 416.
Bring next digit (9) of the dividend behind the 416 and repeat the process: 4169 / 470

Advancing to step 8:
470 goes into 4169 8 times with a remainder of 409.
Put 8 as the next digit of the answer. 
Result so far: 33258.0
The remainder is 409 after subtracting 3760 from 4169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 9:
When dividing 4090 by 470, we get 8 with a remainder of 330.
The number 8 becomes the next digit in our result. 
Result so far: 33258.8
Subtracting 3760 from 4090 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
The number 470 fits into 3300 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 33258.87
If we subtract 3290 from 3300, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
470 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 33258.87
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
470 can be fit into 1000 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 33258.8702
If we take 940 away from 1000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
The number 470 fits into 600 1 times, leaving a remainder of 130.
The next digit of our result is 1. 
Result so far: 33258.87021
Deduct 470 from 600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
1300 divided by 470 is 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 33258.870212
If we take 940 away from 1300, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
The number 470 fits into 3600 7 times, leaving a remainder of 310.
The next digit of our result is 7. 
Result so far: 33258.8702127
Deduct 3290 from 3600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 16:
470 can be fit into 3100 6 times, resulting in a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 33258.87021276
Deduct 2820 from 3100 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 33258.87021276, with a leftover of 2.8e-07.
