We look at the division of 50165515 by 891 
The aim is to understand the frequency of 891 in 50165515.

On to step 1:
The number 891 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 891

Step 2:
The number 891 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 891

Moving on to step 3:
891 goes into 501 0 times with a remainder of 501.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 501 leaves us with 501.
Fetch the next digit (6) from the dividend, attach it to 501 and continue: 5016 / 891

On to step 4:
891 goes into 5016 5 times with a remainder of 561.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4455 from 5016 and we're left with 561.
Take the next digit (5) from the dividend and append it to 561, then repeat: 5615 / 891

Step 5:
When dividing 5615 by 891, we get 6 with a remainder of 269.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 5346 from 5615, we get 269.
Include the next digit (5) from the dividend after 269, then repeat: 2695 / 891

Let's proceed to step 6:
If we divide 2695 by 891, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
Subtract 2673 from 2695 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 891

Going ahead to step 7:
When dividing 221 by 891, we get 0 with a remainder of 221.
The next digit of our result is 0. 
Result so far: 5630.0
The remainder is 221 after subtracting 0 from 221.
Fetch the next digit (5) from the dividend, attach it to 221 and continue: 2215 / 891

Step 8:
If we divide 2215 by 891, we get 2 and a remainder of 433.
Use 2 as the next digit of our solution. 
Result so far: 56302.0
If we subtract 1782 from 2215, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 9:
If we divide 4330 by 891, we get 4 and a remainder of 766.
Put 4 as the next digit of the answer. 
Result so far: 56302.4
If we subtract 3564 from 4330, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Advancing to step 10:
The number 891 fits into 7660 8 times, leaving a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 56302.48
If we subtract 7128 from 7660, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 11:
5320 divided by 891 is 5 with a remainder of 865.
The next digit of our result is 5. 
Result so far: 56302.485
Subtracting 4455 from 5320 leaves us with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Moving on to step 12:
If we divide 8650 by 891, we get 9 and a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 56302.4859
Deduct 8019 from 8650 and we're left with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 13:
6310 divided by 891 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 56302.48597
The remainder is 73 after subtracting 6237 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
If we divide 730 by 891, we get 0 and a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 56302.48597
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 15:
7300 divided by 891 is 8 with a remainder of 172.
The next digit of our result is 8. 
Result so far: 56302.4859708
Deduct 7128 from 7300 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 16:
The number 891 fits into 1720 1 times, leaving a remainder of 829.
Record the quotient 1 as the next digit in the result. 
Result so far: 56302.48597081
If we take 891 away from 1720, we end up with 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Our division results in 56302.48597081 with a remaining 8.29e-07.
