We look at the division of 15285457 by 893 
The aim is to understand the frequency of 893 in 15285457.

On to step 1:
The number 893 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 893

Let's proceed to step 2:
When dividing 15 by 893, we get 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.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 893

Going ahead to step 3:
The number 893 fits into 152 0 times, leaving a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Bring next digit (8) of the dividend behind the 152 and repeat the process: 1528 / 893

Moving on to step 4:
The number 893 fits into 1528 1 times, leaving a remainder of 635.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 893 from 1528 and we're left with 635.
Fetch the next digit (5) from the dividend, attach it to 635 and continue: 6355 / 893

On to step 5:
If we divide 6355 by 893, we get 7 and a remainder of 104.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 6251 from 6355 and we're left with 104.
Grab the next digit (4) from the dividend, add it to 104, then carry on: 1044 / 893

On to step 6:
1044 divided by 893 is 1 with a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 171.0
If we subtract 893 from 1044, we get 151.
Append the next digit (5) from the dividend to 151 and continue with: 1515 / 893

Going ahead to step 7:
893 goes into 1515 1 times with a remainder of 622.
The number 1 becomes the next digit in our result. 
Result so far: 1711.0
If we subtract 893 from 1515, we get 622.
Fetch the next digit (7) from the dividend, attach it to 622 and continue: 6227 / 893

Moving on to step 8:
893 can be fit into 6227 6 times, resulting in a remainder of 869.
Use 6 as the next digit of our solution. 
Result so far: 17116.0
The remainder is 869 after subtracting 5358 from 6227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

On to step 9:
If we divide 8690 by 893, we get 9 and a remainder of 653.
The next digit of our result is 9. 
Result so far: 17116.9
Subtracting 8037 from 8690 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 10:
893 can be fit into 6530 7 times, resulting in a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 17116.97
Subtracting 6251 from 6530 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 11:
When dividing 2790 by 893, we get 3 with a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 17116.973
The remainder is 111 after subtracting 2679 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 12:
If we divide 1110 by 893, we get 1 and a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 17116.9731
Deduct 893 from 1110 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 13:
When dividing 2170 by 893, we get 2 with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 17116.97312
Subtract 1786 from 2170 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 14:
If we divide 3840 by 893, we get 4 and a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 17116.973124
The remainder is 268 after subtracting 3572 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 15:
The number 893 fits into 2680 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 17116.9731243
If we take 2679 away from 2680, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 16:
10 divided by 893 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 17116.9731243
If we subtract 0 from 10, 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.

The final outcome is 17116.9731243, with a leftover of 1e-08.
