We're dividing 87073897 by 470 
The aim is to understand the frequency of 470 in 87073897.

Going ahead to step 1:
470 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 470

Advancing to step 2:
470 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 470

Moving on to step 3:
The number 470 fits into 870 1 times, leaving a remainder of 400.
The next digit of our result is 1. 
Result so far: 1.0
If we take 470 away from 870, we end up with 400.
Bring next digit (7) of the dividend behind the 400 and repeat the process: 4007 / 470

Moving on to step 4:
470 goes into 4007 8 times with a remainder of 247.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3760 from 4007 and we're left with 247.
Fetch the next digit (3) from the dividend, attach it to 247 and continue: 2473 / 470

On to step 5:
If we divide 2473 by 470, we get 5 and a remainder of 123.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtract 2350 from 2473 to get 123.
Grab the next digit (8) from the dividend, add it to 123, then carry on: 1238 / 470

Advancing to step 6:
When dividing 1238 by 470, we get 2 with a remainder of 298.
Write down 2 as next digit of the result. 
Result so far: 1852.0
Subtracting 940 from 1238 leaves us with 298.
Grab the next digit (9) from the dividend, add it to 298, then carry on: 2989 / 470

Advancing to step 7:
The number 470 fits into 2989 6 times, leaving a remainder of 169.
Write down 6 as next digit of the result. 
Result so far: 18526.0
If we take 2820 away from 2989, we end up with 169.
Take the next digit (7) from the dividend and append it to 169, then repeat: 1697 / 470

Going ahead to step 8:
470 can be fit into 1697 3 times, resulting in a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 185263.0
The remainder is 287 after subtracting 1410 from 1697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 9:
2870 divided by 470 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 185263.6
The remainder is 50 after subtracting 2820 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 470 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 185263.61
Subtract 470 from 500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
470 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 185263.61
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
The number 470 fits into 3000 6 times, leaving a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 185263.6106
If we take 2820 away from 3000, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
When dividing 1800 by 470, we get 3 with a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 185263.61063
Deduct 1410 from 1800 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
470 goes into 3900 8 times with a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 185263.610638
Subtracting 3760 from 3900 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.

Advancing to step 15:
470 can be fit into 1400 2 times, resulting in a remainder of 460.
The next digit of our result is 2. 
Result so far: 185263.6106382
Subtract 940 from 1400 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
When dividing 4600 by 470, we get 9 with a remainder of 370.
The next digit of our result is 9. 
Result so far: 185263.61063829
Subtracting 4230 from 4600 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 185263.61063829, with a leftover of 3.7e-07.
