We're dividing 7213665 by 470 
The aim is to understand the frequency of 470 in 7213665.

On to step 1:
When dividing 7 by 470, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 470

Moving on to step 2:
470 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 470

Moving on to step 3:
721 divided by 470 is 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 470 from 721 and we're left with 251.
Grab the next digit (3) from the dividend, add it to 251, then carry on: 2513 / 470

Going ahead to step 4:
The number 470 fits into 2513 5 times, leaving a remainder of 163.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2350 from 2513, we get 163.
Include the next digit (6) from the dividend after 163, then repeat: 1636 / 470

Advancing to step 5:
If we divide 1636 by 470, we get 3 and a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 226 after subtracting 1410 from 1636.
Append the next digit (6) from the dividend to 226 and continue with: 2266 / 470

Going ahead to step 6:
If we divide 2266 by 470, we get 4 and a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 1534.0
Subtract 1880 from 2266 to get 386.
Fetch the next digit (5) from the dividend, attach it to 386 and continue: 3865 / 470

Moving on to step 7:
If we divide 3865 by 470, we get 8 and a remainder of 105.
Record the quotient 8 as the next digit in the result. 
Result so far: 15348.0
Deduct 3760 from 3865 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 8:
470 can be fit into 1050 2 times, resulting in a remainder of 110.
The next digit of our result is 2. 
Result so far: 15348.2
If we take 940 away from 1050, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
1100 divided by 470 is 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 15348.22
If we take 940 away from 1100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 15348.22, with a leftover of 0.16.
