We look at the division of 77310957 by 893 
The aim is to understand the frequency of 893 in 77310957.

On to step 1:
893 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 893

Moving on to step 2:
77 divided by 893 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 893

Advancing to step 3:
The number 893 fits into 773 0 times, leaving a remainder of 773.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 773 to get 773.
Fetch the next digit (1) from the dividend, attach it to 773 and continue: 7731 / 893

On to step 4:
893 goes into 7731 8 times with a remainder of 587.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7144 from 7731, we get 587.
Grab the next digit (0) from the dividend, add it to 587, then carry on: 5870 / 893

Let's proceed to step 5:
893 goes into 5870 6 times with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 5358 from 5870 leaves us with 512.
Grab the next digit (9) from the dividend, add it to 512, then carry on: 5129 / 893

Advancing to step 6:
If we divide 5129 by 893, we get 5 and a remainder of 664.
The next digit of our result is 5. 
Result so far: 865.0
If we subtract 4465 from 5129, we get 664.
Fetch the next digit (5) from the dividend, attach it to 664 and continue: 6645 / 893

Advancing to step 7:
893 can be fit into 6645 7 times, resulting in a remainder of 394.
The next digit of our result is 7. 
Result so far: 8657.0
Deduct 6251 from 6645 and we're left with 394.
Include the next digit (7) from the dividend after 394, then repeat: 3947 / 893

Let's proceed to step 8:
The number 893 fits into 3947 4 times, leaving a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 86574.0
The remainder is 375 after subtracting 3572 from 3947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
3750 divided by 893 is 4 with a remainder of 178.
The next digit of our result is 4. 
Result so far: 86574.4
Subtracting 3572 from 3750 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
893 goes into 1780 1 times with a remainder of 887.
Record the quotient 1 as the next digit in the result. 
Result so far: 86574.41
Subtract 893 from 1780 to get 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Advancing to step 11:
893 goes into 8870 9 times with a remainder of 833.
Put 9 as the next digit of the answer. 
Result so far: 86574.419
Subtracting 8037 from 8870 leaves us with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Advancing to step 12:
If we divide 8330 by 893, we get 9 and a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 86574.4199
Subtract 8037 from 8330 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final outcome is 86574.4199, with a leftover of 0.00293.
