We divide 21476116 by 287
The aim is to understand the frequency of 287 in 21476116.

Step 1:
If we divide 2 by 287, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 287

Moving on to step 2:
The number 287 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 287

On to step 3:
When dividing 214 by 287, we get 0 with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 287

Step 4:
If we divide 2147 by 287, we get 7 and a remainder of 138.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 138 after subtracting 2009 from 2147.
Include the next digit (6) from the dividend after 138, then repeat: 1386 / 287

Advancing to step 5:
1386 divided by 287 is 4 with a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 1148 from 1386, we get 238.
Grab the next digit (1) from the dividend, add it to 238, then carry on: 2381 / 287

Going ahead to step 6:
If we divide 2381 by 287, we get 8 and a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 748.0
Subtract 2296 from 2381 to get 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 287

Let's proceed to step 7:
287 can be fit into 851 2 times, resulting in a remainder of 277.
The next digit of our result is 2. 
Result so far: 7482.0
Subtract 574 from 851 to get 277.
Include the next digit (6) from the dividend after 277, then repeat: 2776 / 287

On to step 8:
287 can be fit into 2776 9 times, resulting in a remainder of 193.
The next digit of our result is 9. 
Result so far: 74829.0
If we subtract 2583 from 2776, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
When dividing 1930 by 287, we get 6 with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 74829.6
If we take 1722 away from 1930, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
The number 287 fits into 2080 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 74829.67
Subtracting 2009 from 2080 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
The number 287 fits into 710 2 times, leaving a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 74829.672
If we take 574 away from 710, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
If we divide 1360 by 287, we get 4 and a remainder of 212.
The next digit of our result is 4. 
Result so far: 74829.6724
The remainder is 212 after subtracting 1148 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
The number 287 fits into 2120 7 times, leaving a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 74829.67247
If we subtract 2009 from 2120, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 14:
If we divide 1110 by 287, we get 3 and a remainder of 249.
The number 3 becomes the next digit in our result. 
Result so far: 74829.672473
Subtracting 861 from 1110 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 15:
If we divide 2490 by 287, we get 8 and a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 74829.6724738
Deduct 2296 from 2490 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 16:
When dividing 1940 by 287, we get 6 with a remainder of 218.
Record the quotient 6 as the next digit in the result. 
Result so far: 74829.67247386
Deduct 1722 from 1940 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 74829.67247386, with a leftover of 2.18e-07.
