Let's divide 80386877 by 913
The aim is to understand the frequency of 913 in 80386877.

Moving on to step 1:
The number 913 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 913

Advancing to step 2:
When dividing 80 by 913, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 913

Let's proceed to step 3:
The number 913 fits into 803 0 times, leaving a remainder of 803.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 803 to get 803.
Include the next digit (8) from the dividend after 803, then repeat: 8038 / 913

Advancing to step 4:
913 goes into 8038 8 times with a remainder of 734.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7304 from 8038 and we're left with 734.
Bring next digit (6) of the dividend behind the 734 and repeat the process: 7346 / 913

Advancing to step 5:
The number 913 fits into 7346 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 7304 from 7346 to get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 913

Moving on to step 6:
913 goes into 428 0 times with a remainder of 428.
The number 0 becomes the next digit in our result. 
Result so far: 880.0
If we take 0 away from 428, we end up with 428.
Take the next digit (7) from the dividend and append it to 428, then repeat: 4287 / 913

Step 7:
913 can be fit into 4287 4 times, resulting in a remainder of 635.
Write down 4 as next digit of the result. 
Result so far: 8804.0
The remainder is 635 after subtracting 3652 from 4287.
Append the next digit (7) from the dividend to 635 and continue with: 6357 / 913

Advancing to step 8:
When dividing 6357 by 913, we get 6 with a remainder of 879.
Write down 6 as next digit of the result. 
Result so far: 88046.0
If we subtract 5478 from 6357, we get 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Going ahead to step 9:
913 can be fit into 8790 9 times, resulting in a remainder of 573.
Put 9 as the next digit of the answer. 
Result so far: 88046.9
Subtracting 8217 from 8790 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 10:
The number 913 fits into 5730 6 times, leaving a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 88046.96
Deduct 5478 from 5730 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
When dividing 2520 by 913, we get 2 with a remainder of 694.
Record the quotient 2 as the next digit in the result. 
Result so far: 88046.962
Deduct 1826 from 2520 and we're left with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Advancing to step 12:
913 can be fit into 6940 7 times, resulting in a remainder of 549.
Record the quotient 7 as the next digit in the result. 
Result so far: 88046.9627
The remainder is 549 after subtracting 6391 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 13:
The number 913 fits into 5490 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 88046.96276
The remainder is 12 after subtracting 5478 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 913, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 88046.96276
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
When dividing 1200 by 913, we get 1 with a remainder of 287.
The next digit of our result is 1. 
Result so far: 88046.9627601
If we subtract 913 from 1200, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 16:
913 can be fit into 2870 3 times, resulting in a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 88046.96276013
Deduct 2739 from 2870 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Our division results in 88046.96276013 with a remaining 1.31e-07.
